The ShakeAlert system, which has taken ten years to develop, would give a minute's warning of a major quake

 

The ShakeAlert system, which has taken ten years to develop, would give a minute's warning of a major quake

  • System will use 2,000 sensors already in place to look for 'p-waves', precursors to earthquakes
  • Will provide 60 second warning, giving residents 'critical seconds' to prepare
  • U.S. Geological Survey predicts a 99 percent chance of a magnitude-6.7 earthquake or larger in the next 30 years in California

Plans for an £50 million ($80m) Earthquake early warning system for California have been unveiled.

The ShakeAlert system, which has taken ten years to develop, would give a minute's warning of a major quake.

Experts say this would give residents critical time for residents to 'duck and cover' and for utilities to power down.

A simulation of a major earthquake along the an Andreas Fault, from the Salton Sea to downtown Los Angeles. Researchers today launched a bill for $80m of funding for an early warning system for the whole of Californai, which would use 2,000 sensors already in place to look for waves that signal the start of a fault line rupturing.

HOW SOPHISTICATED SHAKEALERT COULD SAVE LIVES

The system is based on a highly sophisticated algorithm that can send out a signal from any one of the 2,000 quake-detecting instruments already in place up and down the state.

An alert would go out whenever the system senses a temblor's first pulse of short shock waves - known as P waves - that speed through the ground just as a seismic fault starts to rupture.

Those waves cause no damage, but they are followed by the longer and more destructive pulses known as S-waves.

The ShakeAlert system instantly predicts the quake's magnitude and also calculates the time in seconds when the damaging shock waves will reach any region in California where people are equipped to receive the signal.

The warning time will depend on the distance between a quake's epicenter and the location where the S-waves will arrive.

For example, the researchers said, in one test of the ShakeAlert system last year, a very small quake hit near the epicenter of the deadly 1989 Loma Prieta temblor.

The system correctly predicted that its magnitude would be only 3.5 and warned San Francisco locations that its shock waves would reach there exactly 25 seconds after the quake ruptured near Santa Cruz.

It uses a network of 2,000 quake-detecting instruments now in place up and down the state.

Its backers say it could warn emergency workers and the public as much as a full minute before a big quake ruptures the ground along any of the faults in the state.

There is a 99 percent chance of a magnitude-6.7 earthquake or larger in the next 30 years in California because of the number of fault lines in the region, the biggest of which is the 810 mile San Andreas Fault that forms the tectonic boundary between the Pacific Plate and the North American Plate.

Using the new system, an alert would go out whenever the system senses the first pulse of short shock waves - known as P waves - that speed through the ground just as a seismic fault starts to rupture.

California senator Alex Padilla, said his bill, SB135, is based on recent advances in preparing the California warning system to operate.

Padilla, an MIT-trained engineer from the San Fernando Valley and a former space systems software specialist,  said it could provide 'critical seconds for teachers to get their pupils to duck and cover, for drivers to pull to the side of the road, for trains to stop, and for utilities to power down.'

The plans, unveiled at a news conference at the California Institute of Technology, are have been under development for a decade, and include studies of other early warning systems in Japan, Mexico and other quake-prone nations.

Padilla estimated it would take $80 million to develop a statewide version of ShakeAlert through the California Emergency Management Agency, and $20 million more in annual operating costs.

'But an investment like that is a no-brainer,' he said.

'If you think about the lives we can save, the injuries we can reduce, and the billions upon billions of damages associated with every large earthquake, the system would more than pay for itself.'

The researchers say the scheme is now ready.

'We're ready to build it up right now,' said Richard M. Allen, director of the UC Berkeley Seismological Laboratory.

'It's ready for prime time.'

The system's test phases have proved so successful that BART trains in San Francisco are already equipped to stop instantly whenever the system flashes a hazard warning for the are, Allen said. Lucy Jones, senior adviser for risk reduction for the U.S. Geological Survey (USGS), one of the monitoring network partners, said a lot of the technology needed for the system is already in place.

'If we were building it from scratch, it would cost $650 million,' she said.

It would take from one to three years to fully launch the new system, Jones said.

The system is based on a highly sophisticated algorithm that can send out a signal from any one of the 2,000 quake-detecting instruments now in place up and down the state.

An alert would go out whenever the system senses a temblor's first pulse of short shock waves - known as P waves - that speed through the ground just as a seismic fault starts to rupture.

CALIFORNIA - A STATE BLIGHTED BY EARTHQUAKES

California has suffered a number of major earthquakes, with a 1906 quake reducing much of the centre of San Francisco to rubble in what is considered the worst natural disaster in U.S. history.

The subsequent fire that engulfed the city left more than 3,000 dead and thousands more injured.

The Great Earthquake measured 7.9 on the Richter Scale as was felt as far away as Orgeon, Los Angeles and Nevada.

Around 227,000 and 300,000 people were left homeless out of a population of about 410,000 and lead to refugee camps set up along the coast, which were still operational two years after the quake.

The cost of the damage from the earthquake was estimated at the time to be around $400million, which is around $9.5 billion in today’s money.

Los Angeles has also been hit in recent years.

On January 17, 1994, the Northridge earthquake hit Reseda, a neighborhood in Los Angeles, California, lasting for about 10–20 seconds, causing major damage to building, and freeways to collapse, with strong ground motion felt as far away as Las Vegas, Nevada, about 220 miles (360 km) from the epicenter.

Could 'hover homes' protect California from the big one? Firm reveals plans to raise houses on giant magnets in event of quake

  • System will be connected to ShakeAlert early warning system
  • Homes will rise up from ground moments before quake hits
  • System will use powerful magnets to raise homes above the ground
  • Firm is also developing a hoverboard for personal use

Researchers have revealed plans for a 'hover home' than can simply rise up off the ground in the event of an earthquake.

It would use giant magnets to lift homes for the duration of a quake, avoiding damage.

The firm behind the project is also developing a hoverboard - and said it hopes to apply the same technology to houses.

Homes are built on a 'cushion' that can be filled with a water or gas to raise them in the event of an earthquake, causing them to hover while the buffer material takes the brunt of the quake. a new version will use powerful magnets to do the same job, the firm said.

Homes are built on a 'cushion' that can be filled with a water or gas to raise them in the event of an earthquake, causing them to hover while the buffer material takes the brunt of the quake. a new version will use powerful magnets to do the same job, the firm said.

SHAKEALERT EARLY WARNING

With funding from the U.S. Geological Survey (USGS) and a grant from the Gordon and Betty Moore Foundation, a consortium of universities developed ShakeAlert to rapidly detect earthquakes and send secure alerts.

ShakeAlert uses the geophysical networks operated by University of California Berkeley, California Institute of Technology, University of Washington, and the USGS, which has successfully detected California earthquakes and predicted the shaking before it could be felt.

Greg Henderson, co-founder and CEO at Arx Pax told Business Insider that although the firm has patents for a system using water or gas to raise homes, a new version would use magnets instead of liquid.

'Our goal is to eliminate structural movement by pinpointing the exact time an object or building's 'landing gear' should retract and activate the hover engines.' he said.

To hover a three-story house for the average earthquake length of 90 seconds, it would use the energy of five car batteries, or cost around $13 using PG&E's rates, Henderson calculated.

Instead of building large water-filled bases and foundations, Arx Pax's new vision would require installation of the hover engines and an earthquake-proof base.

'When we receive warning of an earthquake, the computer turns on the hover engines,' Henderson explained.

'All of that happens at the speed of light.'

The original project was described as a 'patented three-part foundation system, a more cost effective means of decoupling an object or building from the earth to provide real protection against earthquakes, floods and sea-level rise.'

It consists of a containment vessel, a buffer medium and a construction platform.

The construction platform rests on the buffer medium which rests on the containment vessel.

A building can then be built on the construction platform, according to the patent.

The buffer medium can be a fluid, a gas or a liquefiable solid.

'In the case of a liquid buffer medium, the construction platform can be designed to displace enough of the buffer medium such that the platform and any building constructed on the platform 'float' on the buffer medium.

'The buffer medium can be selected such that seismic forces, and in particular lateral forces which are known to be most damaging to building an earthquake, are not greatly transmitted through the medium.

'Water is one an example of a potential buffer medium that has this property.'

The firm's hoverboard uses four electromagnets to push against the floor, making the board float an inch off the ground, but will only work over metal surfaces - for now

HOW DOES IT WORK?

The Hendo Hoverboard uses four 'hover engines' which emit magnetic fields that push against each other.

The magnets only work as long as metal conductor is used in the surface underneath. So the board underneath the Hendo can be aluminum and copper to work, for instance.

The innovation here is in the efficiency of the induction process and the ability to control the movements of the hovering objects.

The system claims to be able to carry 40lbs (18kg) and has a battery that lasts for around seven minutes.

Arx Pax, creator of the Hendo Hoverboard also said that it is integrating the ShakeAlert earthquake early-warning software into its plan.

'The ShakeAlert program aligns well with our long-term vision,'

'Weaving ShakeAlert into our MFA seismic isolation solution provides a valuable new tool to architects, engineers, and developers who are looking for a better way to build in areas affected by earthquakes.

ShakeAlert uses the geophysical networks operated by University of California Berkeley, California Institute of Technology, University of Washington, and the USGS, which has successfully detected California earthquakes and predicted the shaking before it could be felt.

'Arx Pax's new MFA base isolation technology combined with the ShakeAlert early-warning system will allow state-of-the-art seismic protection and vibration control for buildings, operating rooms, highly calibrated instruments and much more,' said Dr. Jennifer Strauss, external relations officer at Berkeley Seismological Laboratory.

'We are excited by the collaboration and vision Arx Pax has to offer.'

Just how realistic IS California earthquake disaster movie San Andreas? Seismologist reveals all

  • In San Andreas film,Southern California is rocked by a powerful magnitude-9.1 quake followed by even stronger magnitude-9.6 in Northern California
  • U.S. Geological Survey seismologist said earthquakes this large are near impossible because San Andreas fault is not long or deep enough
  • Seismologist Susan Hough said that earthquake-prediction technology hasn't advanced as far as it shows in the film
  • Hough said though a tsunami hits in the film, that wouldn't happen in reality - but added that the fault will break again without warning

The San Andreas Fault awakens, unleashing back-to-back jolts that leave a trail of misery from Los Angeles to San Francisco. Skyscrapers crumble. Fires erupt. The letters of the Hollywood sign topple. Tsunami waves swamp the Golden Gate Bridge.

Hollywood's favorite geologic bad guy is back in 'San Andreas' - a fantastical look at one of the world's real seismic threats.

But film viewers might ask as they watch the film, just how accurate is it?

THE SAN ANDREAS FAULT

The San Andreas system in Northern California consists of five major branches with an overall length of about 1,25O miles.

Experts say there is a 99 percent chance of a magnitude-6.7 earthquake or larger in the next 30 years in California because of the number of fault lines in the region.

The San Andreas Fault that forms the tectonic boundary between the Pacific Plate and the North American Plate is the biggest.

The San Andreas has long been considered one of the most dangerous earthquake faults because of its length.

At nearly 800 miles long, it cuts through California like a scar and is responsible for some of the largest shakers in state history.

In the film, opening this Friday, a previously unknown fault near the Hoover Dam in Nevada ruptures and jiggles the San Andreas.

Southern California is rocked by a powerful magnitude-9.1 quake followed by an even stronger magnitude-9.6 in Northern California.

The San Andreas is notorious for producing big ones, but a magnitude-9 or larger is virtually impossible because the fault is not long or deep enough, U.S. Geological Survey seismologist Susan Hough told the Associated Press.

Despite the implausible plot, however, she said the San Andreas will indeed break again, and without warning

The most powerful tremors in recorded history have struck along offshore subduction zones where one massive tectonic plate dives beneath another.

The 1960 magnitude-9.5 quake off Chile is the current world record holder.

In 2008, the USGS led a team of 300 experts that wrote a script detailing what would happen if a magnitude-7.8 hit the southern San Andreas. They wanted to create a science-based crisis scenario that can be used for preparedness drills.

But, Hough added, when it does break again, it will not be like the film, where multiple magnitude-9 earthquakes hit across California and can be fest from as far as the East Coast

The lesson: It doesn't take a magnitude-9 or greater to wreak havoc. Researchers calculated a magnitude-7.8 would cause 1,800 deaths and 50,000 injuries.

Hundreds of old brick buildings and concrete structures and a few high-rise steel buildings would collapse.

Computer models show the San Andreas is capable of producing a magnitude-8.3 quake, but anything larger is dubious.

In the film, Lawrence Hayes, a fictional seismologist at California Institute of Technology, notices spikes in 'magnetic pulses' that light up California like a Christmas tree, heralding a monster quake.

Despite a century of research, in reality earthquake prediction remains elusive. Scientists can't predict when a jolt is coming and are generally pessimistic about ever having that ability.

Every warning sign scrutinized - animal behavior, weather patterns, electromagnetic signals, atmospheric observations, levels of radon gas in soil or groundwater - has failed.

'We wish it were as simple as the movie portrays. It isn't. Researchers have scoured every imaginable signal trying to find reliable precursors, but nothing has panned out,' Hough said.

The latest focus has been on creating early warning systems that give residents and businesses a few seconds heads up after a quake hits, but before strong shaking is felt.

Japan has the most advanced seismic alert system in the world while the United States is currently testing a prototype.

And, unlike the film, the San Andreas can't spawn tsunamis.

Most tsunamis are triggered by underwater quakes, but they can also be caused by landslides, volcanoes and even meteor impacts.

Giant tsunami waves are formed when the Earth's crust violently shifts, displacing huge amounts of seawater.

The larger the magnitude, the more these waves can race across the ocean without losing energy.

The San Andreas is strike-slip fault, in which opposing blocks of rocks slide past each other horizontally.

THE 1906 EARTHQUAKE

The M 7.8 San Francisco earthquake of 1906 struck the coast at 5.12 am on 18 April 18. Devastating fires lasting several days broke out in the city.

As a result about 3,000 people died and over 80 percent of San Francisco was destroyed.

The earthquake and resulting fire are remembered as one of the worst natural disasters in the history of the US alongside the Galveston Hurricane of 1900 and Hurricane Katrina in 2005.

A big San Andreas quake can spark fires and other mayhem, but it can't displace water and flood San Francisco.

Hough said the movie got one aspect right: The tide suddenly ebbing out signals a tsunami is coming.

More than 80 - mostly small - tsunamis have been observed along California's coast in the past, triggered mainly by faraway quakes.

In the movie, the scientist warned that shaking would be felt on the East Coast.

But even the largest possible San Andreas quake won't rattle the East Coast.

While seismic waves from great quakes can make the Earth reverberate like a bell, the ringing can only be detected by sensitive instruments because it's so low.

Historical accounts show shaking from the 1906 San Andreas quake was barely felt in western Nevada and southern Oregon, Hough said.

When the ground starts to shake, in the film, the seismologist played by Paul Giamatti makes the ideal public service announcement: 'Drop, cover and hold on.'

+8

Hough did say, however, that having Paul Giamatti and Dwayne Johnson (pictured) accurately tell people how to take cover during an earthquake is 'one heck of a PSA'

Since 2008, millions of people in California and elsewhere have participated in yearly disaster drills in which they practice diving under a table and learn other preparedness tips.

If you're outdoors when the ground moves, experts recommend bracing against a wall, similar to what search-and-rescue helicopter pilot Ray Gaines, played by Dwayne 'The Rock' Johnson, told scared survivors in the movie

Stunning pictures of Amazon 'Lost World' the size of Wales - home to uncontacted tribes and undiscovered animals - that will finally be protected from loggers after nine year battle

  • The 5.9 million acre Sierra del Divisor stretches for 600 miles along Peru's border with Brazil in the Amazon
  • It is home to hundreds of species of plant and wildlife, as well as at least one ancient South American tribe
  • But it was under threat from loggers and miners desperate to tap the natural resources it hides within
  • Peruvian government about to  make it a national park, which will protect the Sierra del Divisor for years to come

A stunning rainforest paradise the size of Wales which hides uncontacted tribes and undiscovered animals amongst its soaring green canopies is expected to be saved from almost certain ruin this week, as environmentalists win a nine-year battle to protect this jewel of the Amazon from logger and miners.

The 5.9million acre Sierra del Divisor, which climbs out from an immense plain of unbroken rainforest, is expected to be turned into the Amazon's newest national park, stretching for 600 miles along the Peruvian border with Brazil.

It comes after years of fighting between environmentalists and those who want to exploit its vast natural resources - including the trees, oil and significant mineral deposits.

Those fighting for the protection of the Sierra del Divisor have warned greed risks destroying the earthly paradise, which, like something from Sir Arthur Conan Doyle's the Lost World, is largely unexplored and people with tribes believed to have never come into contact with other people.

The vast wilderness, 20 hours by boat from the nearest town, is also home to 3,500 plant species and 760 animal species, including Jaguar and South American Tapir.

Its lush forests contain plunging waterfalls, hidden lakes and soaring conical dormant volcanoes - the only ones in the Amazonian rainforest - and is known locally as 'sina jonibaon manan,' or 'Land of the fierce people,' a nod to the indigenous Iskanawa tribe who retreated into the area when European settlers landed in Peru in the 16th century.

The Iskonowa, a tribe with just 300 to 400 men, women and children, live in voluntary isolation but have moved deeper and deeper in to the rainforest in recent years to escape illegal miners and loggers who began to encroach on the rainforest in recent years.

But they aren't the only human's living amongst the trees: expeditions to the interior have seen footprints and charred fires which are believed to belong to further, uncontacted, tribes eking out a near primitive existence in the forest.

But all this was at serious risk. 

Until now, the Sierra del Divisor was a reserved zone and enjoyed little legal protection, and over the last few years, there has been in increase in mining, logging and oil exploration, with bands of informal loggers and gold miners threatening the forests' unique nature.

Unchecked, experts fear such activity would destroy the area within years.

But this week, after previous governments procrastinated for years over offering the protection the area needs, President Ollanta Humala is expected to rubber stamp the local environment ministry's categorisation of the area as a national park.

Fantasy island!

  • The Island of Dominica is a natural wonder, with two thirds of its 289 square miles covered in lush rainforest
  • The 2015 Dominica Film Challenge enlisted six teams of filmmakers to capture the beauty of the island
  • Each team of two was given an all-expenses paid week on the island to explore its natural wonders
  • While some entrants focussed on action and adventure, others highlights local people and their food

With two thirds of its 289 square miles covered by tropical rainforest, adventure isn't hard to come by on the island of Dominica - unspoiled beauty and natural wonder are its obvious and indisputable calling cards.

The 70,000 locals know this though. To get the word out to the world, the Discover Dominica Authority invited emerging filmmakers from all around the world to enjoy the island for themselves and give their own unique perspective as part of the 2015 Dominica Film Challenge.

Six pairs of adventurous storytellers were chosen after a worldwide search to take an all-expenses paid expedition around the West Indian island. They would explore for a week, interact with the locals and report back with their unique view in the form of a short film.

Some filmmakers chose to go swimming with horses in the ocean and take in the classic natural tourism sites and attractions, such as the American duo of presenter Alison Teal and photographer Sarah Lee.

Teal, who describes the island as a 'real-life Disneyland' and a 'true fantasy island', takes in beaches, waterfalls and goes horse-riding - while always wearing a bikini.

Others chose to take inspiration from a local writer and the island's wild expanse, such as Vancouver-based creative company Union Production.

Beautiful landscapes from boats and the banks of streams inspire some of the artists while action sports and the smiling faces of locals inspire others.

Divers and hikers alike adore Dominica, which is home to 1,200 plant species along with secluded beaches, hot geothermal springs and waterfalls - there's good reason it's known as 'The Nature Island'.

Not to be confused with the Spanish-speaking Dominican Republic, which neighbours Haiti, the tiny island of Dominica sits between Guadeloupe and Martinique on the Eastern Caribbean archipelago.

Forgotten for centuries, it's a saga, told in a new book, of shipwreck, mutiny and murder that scandalised Britain...

  • HMS Wager set out from England in September 1740 to harass the Spanish
  • Also tasked with capturing enemy warships off coast of South America
  • Crew shipwrecked in storm off the coast of South America in May 1741
  • New book reveals how the sailors turned into mutineers and cannibals

Ragged and emaciated, some blind with malnutrition, others wild-eyed with drink, they roamed the island — cutlasses and pistols at the ready.

Since their ship had foundered on rocks off this desolate spot, the men’s exasperated captain had been unable to control them.

Some had formed their own camp away from the main party, returning only to try to pilfer from the paltry food supplies that the captain kept under armed guard.

Once, the hoodlums even attempted to blow him up, laying a trail of gunpowder to his tent, which was discovered just in time.

Doomed: HMS Wager got caught in heavy seas after setting sail from England in 1740

Such mayhem might have been expected from pirates, but these were sailors in His Majesty’s Royal Navy, shipwrecked off the coast of South America.

Yet in a matter of weeks they had turned into mutineers and cannibals, eating chunks of human flesh from corpses washed ashore from the wreck or from those lying unburied on the island.

Shockingly, a cabin boy was found trying to eat the liver of a dead shipmate.

Captain David Cheap, who had been in command of the ship, HMS Wager, was woefully ill-equipped to prevent the descent into chaos. Inexperienced, insecure and hot-tempered, he strove to assert his authority by brutally punishing transgressions, whipping those caught stealing, then leaving them in the open to die of their wounds.

Not surprisingly, such harshness simply alienated more men.

Three weeks after the shipwreck, he intervened in a row between a drunken young midshipman, Henry Cozens, and the ship’s purser, who had fired a pistol at Cozens — though he missed.

Rather than waiting to discover the details, Captain Cheap shot Cozens — whom he disliked — through the cheek.

Then he cruelly refused to let a surgeon tend the injured man, insisting he be left out in the cold to die an agonising death . . . another corpse to add to those littering the island. Worse was to follow.

The disaster of HMS Wager in 1741 is little known today, overshadowed by the more famous mutiny on the Bounty half a century later.

But the horrifying saga of shipwreck, murder and betrayal reveals human nature at its best and worst.

The survivors’ stories became best-selling books in Georgian Britain, with rival and contradictory accounts lapped up by a grimly fascinated public.

Now naval historian Rear Admiral C. H. Layman has used these accounts, together with a never before published letter by Captain Cheap, to reveal what happened when bureaucratic penny-pinching, poor leadership and an abundance of alcohol combined to create a terrifying cocktail on the high seas.

HMS Wager’s voyage had been dogged by ill luck from the start. She was one of six ships that had set out from England in September 1740 to harass the Spanish, with whom Britain was at war, and capture enemy warships off the west coast of South America.

The men lying below decks were drowned 

A rickety former store ship, she had been hastily converted to a fighting role with 28 guns and a crew of 160 men. She was carrying supplies — including, fatefully, large amounts of liquor — for the rest of the ships.

Wager was totally unsuited for the world’s most hostile seas, and so was her crew.

Recruitment difficulties meant that many were old men or invalids with missing limbs, dragged unwillingly from Chelsea Hospital. Some were so crippled they had to be hoisted aboard. A few weeks out to sea, HMS Wager’s first captain fell ill and died. David Cheap, the lieutenant of another vessel, was hastily promoted to the role.

Due to a muddle at the naval dockyards, the ships had not been ready to sail on time and therefore reached Cape Horn, at the tip of South America, when the seas were at their roughest.

One of HMS Wager’s masts snapped off and she became separated from the rest of the ships.

Not long afterwards, Captain Cheap fell down a hatchway and broke his collarbone. The surgeon gave him opiates — though Cheap complained later that he had been drugged without his knowledge. He was still heavily sedated when the boat was hit by a storm.

When she struck the rocks at 4.30am on May 14, 1741, a few men who had been lying below decks sick with scurvy were drowned.

Some of the crew did their utmost to right the ship, but others panicked wildly.

Sixteen-year-old midshipman John Byron, grandfather of the poet Lord Byron, saw one man run amok with a cutlass. Others lay in terror on the deck, ‘bereaved of all sense, like inanimate logs, and were bandied to and fro by the jerks and rolls of the ship’, Byron later wrote.

Another contingent at first refused to leave the ship, which was stuck on the rocks, but hadn’t broken up.

While the others rowed ashore, the remaining sailors smashed open the casks of brandy and wine, dressed themselves in clothes stolen from the officers’ cabins and spent the next few days drinking and brawling.

Eventually, a boat rowed out to the wreck and brought the mutineers ashore, where a furious Captain Cheap knocked the boatswain unconscious.

Now, most of the men had made it to land — only to find they were on an uninhabited island off the coast of what is now Chile, with no shelter and little to eat but wild celery.

Fear and lethargy prevailed. Captain Cheap seemed incapable of formulating a feasible plan for escape from an island that was rapidly becoming a mass grave as starvation and hypothermia took their toll.

By the end of June, 40 men had died of the 140 who had survived the wreck. John Byron, the teenage midshipman, tamed a wild dog and was devastated when his hungry shipmates killed and ate it.

They were like skeletons, mad with hunger 

But a few weeks later he found its rotting paws and, desperate with hunger, ate them raw.

At one point, a party of Indians, as the indigenous people were known, arrived on the island in canoes and shared their shellfish and meat with the crew.

But when some of the sailors made advances on their wives, they left.

A cabal of men, led by the chief gunner John Bulkeley, wanted to sail south and seek help on the Argentine coast. But Captain Cheap insisted on heading north by boat to rejoin the rest of the squadron and capture Spanish ships, despite the men lacking a vessel of their own.

His plan never got off the ground. In October 1741, five months after the wreck, John Bulkeley and his men used Cozens’s murder as an excuse to arrest Captain Cheap, seizing him in his tent and tying him up.

Taking possession of the ship’s longboat — the biggest vessel to survive the wreck — and two other small boats, they set out to sea.

Captain Cheap, the surgeon and one lieutenant were left behind on Wager Island, as it was now known.

Soon they were joined by midshipman John Byron and seven other men who had changed their minds and rowed back in one of the small boats.

Out on the waves, gunner John Bulkeley and his 72 men had only 12 days’ worth of rations between them, no chart and — after their smaller vessel sank — just one overcrowded, open boat.

Surviving on a small handful of flour a day, they grew sick and weak. Eleven men asked to be put ashore on the wild, jungle-fringed coast — and were never seen again.

The remaining mariners became living skeletons, delirious with hunger. A teenage sailor died. Then Thomas Capel, aged just 12, who was accompanied by a man appointed as his guardian, began to fade.

The poor boy tearfully begged his guardian for the 20 guineas that he held for him, so he could buy food from the other sailors to save his life, but the man refused.

Thomas died slowly, whimpering in misery. ‘Hunger is destitute of compassion,’ one of his companions later wrote. After six weeks at sea, most of them were more dead than alive.

Then, a little way up the Atlantic coast of South America, a few men managed to swim ashore at a desolate beach and kill some game. But, in a brutal act of self-preservation — fewer mouths would improve the chances of survival for those on board — once the meat was hoisted on board, the boat sailed off, abandoning eight men on shore.

Their betrayers made it to Rio Grande in southern Brazil and were taken in by the Spanish.

Only 30 men, including their leader John Bulkeley, had survived the 2,500-mile odyssey. In January 1743, John Bulkeley arrived back in England, where he wrote his version of events, a best-selling tale of heroic endurance.

He downplayed suggestions of mutiny or marooning, claiming that he had reluctantly taken on the role of leader.

Bulkeley must have reckoned the only people who could challenge his story were probably dead.

In fact, back on Wager Island, Captain Cheap and his companions were still alive, albeit reduced to eating seaweed and their sealskin shoes.

After many months of procrastination by the Captain and more deaths, they began a long and torturous journey north by sea.

Again, disaster and betrayal beset the party. One of their two small boats, salvaged from the wreck, soon sank, and the men put ashore.

As his men died from hunger, Captain Cheap hoarded food, cruelly eating meat in front of the others.

Some muttered that they should maroon him — then six men made off with the group’s only remaining boat. No more was heard of them.

The five left onshore, Captain Cheap and the young John Byron among them, seemed doomed — until some Indians took them inland in their canoes, forcing them to row though they were weak.

Aged just 12, the boy sailor died whimpering 

The ship’s surgeon died of exhaustion, but after months of canoeing, they reached the island of Chiloe off what is now Chile.

Here, Captain Cheap and his few remaining men recuperated, John Byron even flirting with Spanish ladies, until they were sent to Santiago by the Spanish and eventually put on a ship for England.

Byron’s family had given him up for dead. When he arrived at their London home in 1746, more than five years after he had left, the porter at first tried to shut the door in his face — before a joyous family reunion.

Their homecoming was not the only surprise for John Bulkeley’s crew. Against the odds, some of the game-hunters they had abandoned on the Brazilian coast also made it back. The surviving sailors had been taken prisoner by other Indians and sold on to the Spanish.

They were enslaved for several years on the Spanish warships, before their eventual release and journey home.

The returning men’s saga of betrayals and maroonings flatly contradicted John Bulkeley’s account and gripped the public.

Who was telling the truth? Who were the villains? Who, if any, were the heroes?

A court martial ensued, presided over by the Admiralty Board. After hearing of Captain Cheap’s callous and incendiary behaviour, the Board decided not to press charges of mutiny, preferring to portray the story as one of epic survival.

However, Captain Cheap was excused the loss of his ship and promoted, and the teenage midshipman John Byron eventually became an admiral and returned to the stormy waters off South America, claiming the Falkland Islands for Britain.

In 2006, a team of Chilean and Royal Navy explorers discovered the wreck of HMS Wager.

Lying in shallow waters, the ill-fated ship remains a monument to one of the most barbarous episodes in maritime history, in which the urge for self-preservation prevailed all too often over decency and compassion.
