Lebanon: Specter of civil conflict looms as economic meltdown gives way to violence

In Lebanon, fistfights break out in supermarkets on a nearly daily basis. Long lines snake out of the few gas stations that remain open. Pharmacies have threatened to shutter. Gunfights inexplicably erupt in various parts of the capital. Angry demonstrators have blocked roads around the country, tightening an already stifling economic stranglehold

The infernal scenes threaten to take a turn for the worse.

Increasingly, Lebanon's officials and politicians raise the specter of internal conflict. This comes just 31 years after the end of the country's gruesome 15-year civil war. That black chapter was drawn to a close by a modus vivendi that critics say systematized government corruption, culminating in a financial meltdown that has brought Lebanon, once again, to the brink.

In a statement to CNN this week, Lebanon's caretaker interior minister Mohammed Fahmi said there was a heightened probability of "security breaches such as explosions and assassination attempts" in the country.

That fear is echoed by many high-profile politicians who cite conversations with intelligence agents. In a televised speech on Wednesday, Iran-backed Hezbollah's secretary general Hassan Nasrallah also warned of civil war, drawing a bleak prognosis of the security situation, and calling on the country's fractured political class to band together to stymy the financial tailspin.

But on Lebanon's streets, that same political elite is overwhelmingly unpopular. Even ardent supporters of mainstream parties call for an overhaul of the country's confessional power sharing system, which allots seats by sectarian group. MPs publicly admit their failures, and some of them say that they, too, ought to step down. Leftist groups, such as the communist party, have called for an "escalation" in the country's popular uprising, which began in October 2019 with the aim of overthrowing the ruling class.

But there is little to no agreement about the future of governance in the country. A cabinet formation process has been in deadlock for four months over disputes between Prime Minister-designate Saad Hariri and President Michel Aoun. Hariri has promised that his future government would stop Lebanon's collapse and reengage with the International Monetary Fund (IMF), which last year stopped negotiations with the government over a bailout.

But Hariri faces the grueling task of ushering in stinging economic reforms at a time when his popular mandate has greatly diminished. The fledgling parties that have cropped up in recent years in a bid to replace the elite also appear to lack the political clout needed to dislodge the status quo.

That crisis of leadership has exacerbated Lebanon's financial woes on a spectacular scale. In its Fall 2020 report, the World Bank described Lebanon's economic depression as "deliberate."

The report details exactly what that means: A rapid deceleration of economic growth, a tanking currency, small depositors bearing the lion's share of economic losses, a stunning depletion of the country's resources including its human capital, and a poverty rate surpassing 50% in 2021.

The catastrophe could have been largely avoided, the World Bank says. Lebanon's leaders have -- to the shock of even some of the most cynical observers -- steered clear of enacting policies that could mitigate the financial decline.

The state has done little to nothing to alleviate poverty. Formal capital controls have not been implemented, nearly a year and a half after banks began to limit cash withdrawals to depositors on a discretionary basis. That practice that prompted the capital flight of the super-rich, while the working and middle classes helplessly watched their deposits lost most of their real value.

The country also does not have an official exchange rate platform, leaving the plummeting lira at the mercy of shadowy black markets and the ever-present possibility of currency manipulation.

The economic outlook gets bleaker on a nearly daily basis. The country's currency on the black market has now lost 90% of its October 2019 value. As Lebanon burns through its foreign reserves, caretaker energy minister Raymond Ghajar raised the possibility of 24/7 power cuts during a presser this month, immersing the country in "total darkness."

The food, fuel, and medicine subsidies that served as the country's lifeboat may also soon disappear. This week, caretaker prime minister Hassan Diab said Lebanon would scale back those subsidies and added that most of them could only be maintained until June.

The loss of subsidies could be the watershed moment that threatens to tip Lebanon over to Venezuela-like scenarios, exacerbating the existing food, fuel and medical shortages.

Families living on a minimum wage -- now less than $50 a month -- will be unable to afford basic food staples as inflation skyrockets. Already strained security forces, which must contend with the frustrations of its newly pauperized rank and file, will have to deal with growing crime rates and the possibility of long-simmering political tensions coming to a head.

The only glimmer of hope is the possibility of an imminent political resolution which in turn produces an efficient an

Anti-coup protesters defy Myanmar junta's campaign of fear

Protesters took to the streets across Myanmar again on Saturday, defying the junta which has increasingly sought to crush the uprising with a campaign of violence and fear.

The country has been in turmoil since the military ousted civilian leader Aung San Suu Kyi from power in a February 1 coup, triggering a nationwide uprising as protesters call for a return to democracy.

So far, more than 230 people have been killed in anti-coup unrest, according to a local monitoring group, as security forces have deployed tear gas, rubber bullets and live rounds against anti-coup protesters.

But the movement has pushed ahead -- albeit in smaller numbers.

Local media showed protesters in gas masks gathering in northern Shan state, while in the southern coastal city of Dawei, motorists hoisted posters of Suu Kyi and signs that said "end the dictatorship".

The protesters in Shan state hoisted home-made shields that said "protect unarmed civilians".




Outside of protests, crackdowns by security forces continue on the streets and residential areas across Myanmar, said the Assistance Association for Political Prisoners monitoring group.

"Casualties and unprovoked shootings are increasing day by day," it said.

In the central ruby-producing city of Mogok, local media Myanmar Now reported that a small quarter's night guards were shot overnight.

"One died on the spot last night while two others are in critical condition in the hospital," a rescue team member confirmed to AFP, declining to give more details.

Commercial hub Yangon has emerged as a hotspot for unrest, as security forces armed with guns continue to root out protesters wielding homemade protection gear.

But the resistance movement remains defiant.

"Who says we have to give up because of unequal weapons? We are born for victory," tweeted prominent activist Ei Thinzar Maung, with the hashtag #SpringRevolution.

Tom Andrews, UN special rapporteur on the human rights situation in Myanmar, said the junta could not defeat a population "united in peaceful opposition" against its rule.

"Desperate, it launches ruthless attacks to provoke a violent response to try and justify even more violence," he tweeted Saturday.

"It's not working. The world must respond by cutting their access to money & weapons. Now."

Myanmar garment workers urge global brands to denounce coup

3/19/2021

NEW YORK — Tin Tin Wei used to toil 11 hours a day, six days week sewing jackets at a factory in Myanmar. But she hasn't stitched a single garment since a coup in February.

Instead, the 26-year-old union organizer has been protesting in the streets — and trying to bring international pressure to bear on the newly installed junta.

Her union, the Federation of Garment Workers in Myanmar, and others have been staging general strikes to protest the coup and are urging major international brands like H&M and Mango, which source some of their products in Myanmar, to denounce the takeover and put more pressure on factories to protect workers from being fired or harassed — or worse arrested and killed for participating in the protests.

“If we go back to work and if we work for the system, our future is in the darkness, and we will lose our labour rights and even our human rights,” said Tin Tin Wei, who has been a clothing factory worker since age 13.

The response from companies so far has been mixed. Only a few have said they would curtail their business in Myanmar. Most others have put out statements that stop short of taking action, saying that while they denounce the coup, they want to support the workers by providing them with jobs.

Tin Tin Wei's union and the Confederation of Trade Unions in Myanmar have also been demanding comprehensive international sanctions — not the targeted sanctions some have imposed — to bring down the junta that ousted the civilian government of Aung San Suu Kyi.

As international sanctions were dropped in the mid-2010s when Myanmar began shifting toward democracy after decades of military rule and started to set some labour standards, Western brands looking to diversify their sourcing were attracted to the country's cheap labour. Broad sanctions now would cripple that burgeoning clothing industry, which has been growing rapidly in recent years before the coronavirus pandemic cut orders and eliminated jobs.

Comprehensive sanctions could wreck the livelihoods of more than 600,000 garment workers, but some union leaders say they would rather see massive layoffs than endure military oppression.

“I need to do some sort of sacrifice in the short term for the long term for our next generation," said Tin Tin Wei, who is the sole breadwinner in her family and has been receiving food donations.

The civil disobedience movement, or CDM as it is known, has included railway workers, truck drivers, hospital, bank employees and many others determined to stifle the economy.

The aim is “no participation with the junta at all," Sein Htay, a migrant labour organizer who returned to Myanmar from Thailand said in an emailed comment. “We believe that CDM is really working. So we are motivated to continue."

But violent crackdowns by Myanmar security forces against protesters including garment workers are escalating. Troops shot and killed at least 38 people Sunday in an industrial suburb of Yangon — an area dominated by clothing factories — after Chinese-owned factories were set on fire. Tens of thousands of workers and their families were seen fleeing the area in the days that followed.

The garment industry plays a key role in Myanmar’s economy, particularly the export sector. Roughly a third of Myanmar's total merchandising exports come from textiles and apparel, worth $4.59 billion in 2018. That's up from 9%, or $900 million, in 2012 as international sanctions were dropped, according to the latest data from the European Chamber of Commerce in Myanmar.

Myanmar’s apparel exports mostly go to the European Union, Japan and South Korea because of favourable trade agreements. The U.S. accounts for 5.5% of Myanmar's exports, with clothing, footwear and luggage representing the bulk of that, according to garment trade expert Sheng Lu.

But Myanmar still accounts for a tiny share — less than 0.1% — in U.S. and European Union fashion companies’ total sourcing networks. And there are plenty of other alternatives for brands.

Despite this, many are taking a wait-and-see stance when it comes to any long-term decisions. Experts note it’s not easy to shift products to a different country, nor is it easy to return to Myanmar once companies leave. Furthermore, some argue Western companies play a role in reducing poverty by giving workers in Myanmar opportunities to earn an income while also helping to improve labour standards there.

Factory working conditions were already poor before the February coup, but the labour unions had made some inroads and gave workers hope. And while the National League for Democracy, the party that was ousted in the takeover, wasn’t proactively protecting unions, it didn’t persecute or crack down on them, says Andrew Tillett-Saks, a labour organizer in Southeast Asia who previously was based in Myanmar.

Asian brands have so far remained quiet about the turmoil. The American Apparel & Footwear Association joined other groups like the Fair Labor Association in condemning the coup while urging members to honour existing financial contracts with factories there.

L.L. Bean CEO Steve Smith said he was saddened by the situation in Myanmar, which he visited in 2019. Bean uses several factories and suppliers for three product lines.

Smith said there’s backup production elsewhere, but it’s important not to abandon the country.

Other companies have been more forceful in their response. For instance, Hennes & Mauritz and The Benetton Group have suspended all new orders from factories in Myanmar.

“Although we refrain from taking any immediate action regarding our long-term presence in the country, we have at this point paused placing new orders with our suppliers,? H&M said in a statement. “This is due to our concern for the safety of people and an unpredictable situation limiting our ability to operate in the country.”

Spanish brand Mango said it would work with its trade and union partners, globally and locally in Myanmar, to ensure there’s no retaliation against any factory worker or union leader exercising their civil or union rights.

Moe Sandar Myint, chairwoman of the Federation of Garment Workers in Myanmar who organized small strikes on factory floors that later moved to the streets, said brands aren't doing enough to help workers. She wants to see “concrete action."

Nearly 70% of the garment factories in Myanmar are owned by foreigners, according to the European Chamber of Commerce in Myanmar, and a good chunk of them are Chinese-owned. International brands using the factories don’t directly hire the workers, often depending on a web of contractors and sub-contractors to produce goods for them.

But companies have “an enormous amount of influence in the industry," Tillett-Saks said. “They hold all the power over the supplier."

Tin Tin Wei says escalating intimidation by the military is scaring some employees at her factory. Located in the Hlaing Thayar industrial zone, it unionized five years ago. Out of 900 workers employed at the factory, 700 initially joined the protests but that number dropped to 500 by early March, she said.

Moe Sandar Myint, who’s in hiding and moving from one safe house to another after the police raided her home in early February, said she will keep fighting.

“I cannot allow my generation and my next generation to live through another military leadership,” she said. “This is unacceptable.”

As endangered birds lose their songs, they can't find mate
s

3/17/2021

WASHINGTON — Male songbirds usually learn their tunes from adult mentors. But when aspiring crooners lack proper role models, they hit all the wrong notes — and have less success attracting mates.

For five years, ecologist Ross Crates has tracked the singing ability and breeding success of critically endangered regent honeyeaters. These distinctive black and yellow birds were once common across Australia, but habitat loss since the 1950s has shrunk their population to only about 300 or 400 wild birds today.

While male birds once formed large winter flocks, now they are sparsely distributed across the landscape, so many fly solo. That means fewer honeyeater mentors are nearby during young birds’ impressionable first year.

“Song learning in many birds is a process similar to humans learning languages — they learn by listening to other individuals,” said Crates, who is based at Australian National University.

“If you can’t listen to other individuals, you don’t know what you should be learning.”

The researchers found that a significant portion of male birds appear to be learning tunes exclusively from other species they encounter. About 12% of male regent honeyeaters wind up producing mangled versions of songs typically sung by noisy friarbirds and black-faced cuckooshrikes, among other species.

In some species, such as mockingbirds, song mimicry adds flourish to love songs. But the female regent honeyeaters aren’t impressed.

Unconventional male singers were less successful in wooing mates, the scientists found in research published Tuesday in the journal Proceedings of the Royal Society B. “We think the females are avoiding breeding and nesting with males that sing unusual songs,” Crates said.

For a population already on the brink of extinction, that’s worrisome.

“This research suggests that the loss of a song language once the population reaches a very small size could accelerate their decline,” said Peter Marra, a conservation biologist at Georgetown University who was not involved in the paper.

The precise reason females remained aloof was not clear.

“When male birds sing, it’s like putting out an ad saying, ‘I’m over here, I’m species X, I’m Bob, and I’m really interested in finding a partner,'” said Scott Ramsay, a behavioural ecologist at Wilfrid Laurier University in Ontario, who was not involved in the research.

It could be that female honeyeaters aren’t even recognizing these unconventional singers as potential partners, and so they’re not approaching them, he said. Or it could be that they approach, “but then things go wrong if the males get courtship signals wrong.”

Most male birds spend several months in their first year learning and refining the songs they’ll recite for the rest of their lives. Some birds learn from their fathers, but regent honeyeaters leave the nest before they learn to sing, so the males need to find other mentors.

“We need to be aware of the importance of preserving song culture in birds — it’s possible to have a population that's still genetically viable, but isn’t viable in terms of passing on cultural knowledge,” said Carl Safina, an ecologist at Stony Brook University who was not involved in the research.

“Some elements of what these birds need to do to survive isn’t instinctive, it has to be learned,” he said.

Crates’ team has begun putting their findings into action. To help young birds in captive breeding programs learn their notes, they’ve started playing male song recordings and also housed capable male singers next to young learners. The hope is that these veteran vocalists can pass on their songs to the next generation.

Climate scientist Katharine Hayhoe has book out in September

3/18/2021

NEW YORK — The new chief scientist at the Nature Conservancy, Katharine Hayhoe, has written a book about climate change.

One Signal Publishers announced Wednesday that Hayhoe's “Saving Us” will be released Sept. 21. Hayhoe will combine research and personal stories as she attempts to unite readers, including those who deny the overwhelming evidence of climate change, and motivate them toward action.

“So why aren’t we taking climate change seriously? The missing piece of the puzzle is communication,” Hayhoe said in a statement. “Because it’s so scary and so contentious, we don’t talk about it. And if we don’t talk about it, why would we care? In this book, I want to give people the tools to have constructive conversations about why these issues are relevant to all of us, and how we can work together for change.”

The Nature Conservancy is an international environmental organization founded in 1951. Hayhoe, a climate scientist who teaches public policy and public law at Texas Tech University, hosts the PBS digital series “Global Weirding” and was named a “Champion of the Earth” by the United Nations in 2019.

Pre-embryos made in lab could /SHOULD/ WILL spur research, ethics debates

3/18/2021

WASHINGTON — For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of restrictions on using real embryos
.

Two papers published Wednesday in the journal Nature detail how two teams of scientists independently made such structures.

They stressed that their work is only for research, not reproduction, but it likely will pose new ethical questions.

“Studying early human development is really difficult. It’s basically a black box,” said Jun Wu, a stem cell biologist at the University of Texas, Southwestern Medical Center.

“We believe our model can open up this field,” he said, if “you can test your hypothesis without using human embryos.”

Wu’s team used embryonic stem cells and the second team used reprogrammed skin cells to produce balls of cells that resemble one of the earliest stages of human development.

These balls, called blastocysts, form a few days after an egg has been fertilized but before the cells attach to the uterus to become an embryo. To differentiate their models from blastocysts created through fertilization, the researchers refer to the structures as “iBlastoids” and “human blastoids.”

“They shouldn’t be considered as equal to a blastocyst, although they are an excellent model for some aspects of biology,” said Jose Polo, an epigeneticist at Monash University in Australia who led the second research team.

Both groups stressed that the structures they made were not the same as naturally occurring embryos, and it’s unclear whether they could develop into viable embryos.

“The blastoids are less efficient in terms of generating structures mimicking later stage human embryos,” said Wu, whose team stopped growing the structure in a culture after four days.

Scientists previously generated similar structures of mouse cells in a lab, but this is the first time they have been made from human cells. The new models correspond to about three to 10 days after fertilization, Wu said. Last year, researchers unveiled structures that model cells 18 to 21 days after fertilization.

Research involving human embryos and blastocysts is currently ineligible for federal funding in the U.S., and several states prohibit it outright.

Some scientists now use blastocysts donated from fertility clinics for research into the causes of infertility and congenital diseases. The new work should allow them to do such research at much larger scales, Polo said.

“This capacity to work at scale will revolutionize our understanding of these early stages of human development,” said Polo.

The scientists stressed that their creations were not intended to be used for human reproduction.

“There is no implantation,” said Amander Clark, a stem cell biologist at the University of California, Los Angeles who co-authored the paper with Polo. “These structures are not transferred to a uterus or uterus-like structure,” she said. “There is no pregnancy.”

The distinction between blastocysts derived from fertilization and the structures created in a lab may not be so clear-cut, said Shoukhrat Mitalipov, a human embryologist at Oregon Health and Science University who was not involved in the research.

“Both groups show how closely they resemble real embryos,” he said. “If they are really as good as embryos, should they be treated as embryos?”

“This brings new ethical issues,” he said. “Are they going to be covered as human embryos? Should restrictions apply?”

Scientists previously tried to turn the lab-generated mouse cell structures into embryos, but they were not successful.

The optimal scenario for research is to “get as close to a real embryo as possible so you can learn from it, but not a real embryo so you don’t get into debates about the moral status of embryos,” said Alta Charo, a professor emerita of law and bioethics at University of Wisconsin who was not involved in the papers.

Research from N.S. prof suggests sperm whales taught each other how to avoid whalers

HALIFAX — New research from a team including a Dalhousie University biologist suggests sperm whales taught each other to avoid whalers in the 18th and 19th centuries
.
© Provided by The Canadian Press

A research paper published in the journal Biology Letters Wednesday indicates that in the North Pacific the whales — the same species hunted in Herman Melville’s "Moby Dick" — quickly changed their habits to avoid open-boat whalers.

“What seems to have been going on is that the whales had been learning techniques to avoid this new threat that appeared, these guys in their boats,” Dalhousie University professor Hal Whitehead said in an interview. “They learned very quickly and they learned, it seems, from each other.”

During the 18th and 19th centuries, whalers from Europe and North America searched the world's waters to find new species to exploit, the paper says.

After discovering sperm whales, they searched for the mammals in large, sail-powered whaling ships, and once whales were sighted, hunters would go out in row boats and attempt to strike them with hand-thrown harpoons. If the trip was successful, the bodies were towed back to the ship for oil processing.

Whitehead, co-author of the study, said log books from American whalers in the North Pacific show that successful harpoon strikes fell by about 58 per cent over the first few years of hunting in a region.

“I didn't expect it to be that clear, frankly,” he said of the results. “I was pretty amazed when I looked at it.”

The Halifax university professor said the large mammals may have learned to adopt defensive measures from others in their close social units.

Some of the evasive methods noted in the log books by whalers during the 19th century included swimming upwind to evade the hunters' row boats and getting close enough to attack the vessels.

The biggest change noted in the logs, however, was that the whales abandoned the characteristic defensive behaviour they had adopted against what was previously their main predator: killer whales.

Whitehead said sperm whales gather their young and create a barrier around them while fending off killer whales using their jaws and tails.

"This is exactly the wrong thing when you're faced with Captain Ahab," Whitehead said in reference to the "Moby Dick" skipper, "because to gather in a tight group, it's a lovely, big target for someone throwing a harpoon."

The research paper said fleeing whales possibly made themselves more visible from a distance "by blowing hard and showing their bodies forcefully, so increasing the number of sightings with groups that were not easily struck."

The research also indicated sperm whales could likely sense and co-ordinate behaviour over several kilometres. Sperm whales are highly communicative, Whitehead added, using their massive nose to make powerful sounds.

It's likely a group of sperm whales that had experienced whalers before and figured out how to deal with them communicated their strategy to other pods in the region, he added.

"Since the sperm whales are so social and communal, it makes sense that they do this socially and communally," Whitehead said.

Sharks, Turtles, and Penguins Are All Swimming in Circles. No One Knows Why.

Caroline Delbert 
3/19/2021
© Narazaki et al., Similar circling movements observed across marine megafauna taxa, iScience (2021) Sharrks, turtles, and penguins are all swimming in circles. No one knows why. Could it have something to do with Earth's magnetic field?

A new study shows marine animals swim in circles, and scientists are baffled.

Some circles are likely navigational, while others are for feeding.

Animals studied range from whales to sharks to penguins, making this a widespread behavior.

Scientists have discovered a confounding pattern in nature: Many marine animals are strangely swimming in circles.

The researchers modeled the animals’ behavior using a variety of math ideas and the navigational concept of dead reckoning. In a variety of animals, including turtles, penguins, and a solitary whale shark, the scientists spotted the behavior because of the advent of true 3D sensing of movement.

Why is this happening? No one is exactly sure.
➡ You think science is bad***. So do we. Let’s nerd out over it together.

Lead study author Tomoko Narazaki, of the University of Tokyo, first noticed the circles in a group of turtles she was studying, according to Vice. She and her team moved the turtles specifically to monitor how they would navigate back to their home waters, and even with a destination in mind, they still often swam in circles. Surprised, Narazaki encouraged her colleagues who studied different animals to look at their sensor data as well.

“Examining high-resolution 3D movements of sharks, sea turtles, penguins, and marine mammals, we report the discovery of circling events where animals consecutively circled more than twice at relatively constant angular speeds,” Narazaki and her coauthors write in their study, which appears in iScience.

The scientists gathered the data while the animals—located everywhere from the Cape Verde Islands to Okinawa, Japan—were foraging, swimming home, and returning after nesting. The circles ranged from just a few to dozens in a row. The scientists saw most of the recorded circles during foraging, especially among the sharks:
“For example, a total of 272 circling events were observed in four tiger sharks tagged off Hawaii. Sharks circled 2–30 times at wide-ranging depths but maintained relatively constant depth during each circling event. In addition, circling behaviors previously reported in bottom-feeding sandbar sharks occurred primarily close to the sea floor, suggesting a role in foraging.”

But feeding isn’t the only possible explanation for circling behaviors.“[M]any circling events appear unrelated to foraging,” the researchers report.“For example, a shark-mounted video showed a male tiger shark circling to approach a female for courtship.” And seals circled during the day when their primary foraging time was at night.

The study team suspects the circling of many animals has to do with navigating using the Earth’s magnetic field. The researchers explain:
“Animals might also be able to improve measurement accuracy by taking multiple samples by circling several times. Animals might circle to derive directional/positional cues from the geomagnetic field, especially in navigationally challenging situations.”

In the study, some animals were equipped with sensors and GPS tags, while the scientists themselves observed others. The technology to monitor animals this way, and humanely, is still very new and growing. The scientists say the ideal next step is to record a lot more data and analyze it in a simultaneous way to help identify patterns.

Long dormant volcano comes to life in southwestern Iceland

REYKJAVIK, Iceland — A long dormant volcano on the Reykjanes Peninsula in southwestern Iceland flared to life Friday night, spilling lava down two sides in that area's first volcanic eruption in nearly 800 years.

Initial aerial footage, posted on the Facebook page of the Icelandic Meteorological Office, showed a relatively small eruption so far, with two streams of lava running in opposite directions. The glow from the lava could be seen from the outskirts of Iceland’s capital, Reykjavík, which is about 32 kilometres (20 miles) away.

The Department of Emergency Management said it was not anticipating evacuations because the volcano is in a remote valley, about 2.5 kilometres (1.5 miles) from the nearest road.

Melting glaciers are triggering earthquakes
 in Alaska, study finds


Stacy Liberatore For Dailymail.com

Alaska's melting glaciers may have set the stage for a magnitude 7.8 earthquake in 1958 that triggered a massive avalanche of about 90 million tons of rock down into the narrow inlet of Lituya Bay.

A new study from the University of Alaska Fairbanks Geophysical Institute found ice loss has influenced the timing and location of earthquakes with a magnitude of 5.0 or greater in the area during the past century.

Alaska is home to some of the largest glaciers in the world that weigh thousands of pounds that sink the land beneath.

When these giant glaciers start to melt, the once sunken land quickly rebounds and tectonic plates grind pass each other that results in a seismic event.

Scientists have long feared Alaska's melting glacier could trigger catastrophic natural disasters, such as massive avalanches and landslides, but few have thought about earthquakes.

However, it has been known that ice loss has caused the events in otherwise tectonically stable regions, such as Canada's interior and Scandinavia.

In Alaska, this pattern has been harder to detect, as earthquakes are common in the southern part of the state.

This region is home to massive glaciers, with some thousands of feet thick that cover hundreds of square miles

And with so much weight on top, the land beneath sinks.

When the ice slowly disappear, due to warmer than usual temperatures, the ground springs back like a sponge – moving the entire mantle.

Chris Rollins, the study's lead author who conducted the research while at the Geophysical Institute, said: 'There are two components to the uplift.'

'There's what's called the 'elastic effect,' which is when the earth instantly springs back up after an ice mass is removed.'

'Then there's the prolonged effect from the mantle flowing back upwards under the vacated space.'

The team determined there is a link between the expanding movements of the mantle with massive earthquakes across Southeast Alaska, where glaciers have been melting for more than 200 years.

Southern Alaska sits at the boundary between the continental North American plate and the Pacific Plate, which has lost more than 1,200 cubic miles of ice.

Researchers found the plates grind past each other at about two inches per year -roughly twice the rate of the San Andreas fault in California - resulting in frequent earthquakes.

The disappearance of glaciers, however, has also caused Southeast Alaska's land to rise at about 1.5 inches per year.

Rollins ran models of earth movement and ice loss since 1770, finding a subtle but unmistakable correlation between earthquakes and earth rebound.

When they combined their maps of ice loss and shear stress with seismic records back to 1920, they found that most large quakes were correlated with the stress from long-term earth rebound.

Unexpectedly, the greatest amount of stress from ice loss occurred near the exact epicenter of the 1958 quake that caused the Lituya Bay tsunami.

While the melting of glaciers is not the direct cause of earthquakes, it likely modulates both the timing and severity of seismic events.

When the earth rebounds following a glacier's retreat, it does so much like bread rising in an oven, spreading in all directions.

This effectively unclamps strike-slip faults, such as the Fairweather in Southeast Alaska, and makes it easier for the two sides to slip past one another.

In the case of the 1958 quake, the postglacial rebound torqued the crust around the fault in a way that increased stress near the epicenter as well.

Both this and the unclamping effect brought the fault closer to failure.

'The movement of plates is the main driver of seismicity, uplift and deformation in the area,' said Rollins.

'But postglacial rebound adds to it, sort of like the de-icing on the cake. It makes it more likely for faults that are in the red zone to hit their stress limit and slip in an earthquake.'
