Earthquakes recorded near Alaska volcano dormant 800 years

Published

on


ANCHORAGE, Alaska — Lots of of small earthquakes have been reported close to a volcano in southeast Alaska believed to have been dormant for no less than 800 years.

The reason for the quakes below Mount Edgecumbe, a volcano close to Sitka that resembles Mount Fuji in Japan, usually are not recognized. Nonetheless, they will not be a sign of volcanic exercise, stated Dave Schneider, a analysis geophysicist with the U.S. Geological Survey on the Alaska Volcano Observatory in Anchorage.

Mount Edgecumbe is a 3,200-foot (976-meter) stratovolcano positioned on Kruzof Island, about 15 miles (24 kilometers) west of Sitka. The volcano is a component of a bigger underwater volcanic subject of lava domes and craters.

The quakes are considerably uncommon since temblors within the space are often tectonic, not volcanic, he stated.

“These aren’t essentially associated to volcanic exercise, they might be a tectonic in nature or a mixture of tectonics and the volcano,” he stated. “We actually can’t inform the distinction at this level.”

Proper now, there is no such thing as a want for an enormous quantity of concern, Schneider stated.

“Volcanoes do have swarms of earthquakes that don’t result in eruption,” he stated.

The earthquakes, most of which had been too small to be noticed on a number of seismic stations, continued Wednesday though the frequency has declined.

“I don’t suppose anyone was even conscious that these occurred,” stated Zach Mayville who answered the cellphone at Home of Liquor in Sitka.

He stated there’s been no injury from the quakes.

“We didn’t really feel something,” Mayville stated. “We’ve heard nothing from anyone, so we’re all good.”

The volcano observatory did a retrospective evaluation of earthquake information close to Mount Edgecumbe, which confirmed a small variety of earthquakes began occurring in 2020.

There’s been about 40 quakes that had been positioned within the space within the final two years, about one or two a month, far lower than what’s been recorded this week.

“You’d anticipate many, many earthquakes to be noticed previous to any eruptive exercise if it had been to happen,” Schneider stated. “Earthquake exercise is our greatest indicator of what’s occurring there, and that’s one thing that we’ll be watching intently.”

Alaska has about 90 volcanoes which have been lively within the final 10,000 years, he stated. Most are distant and never often close to a inhabitants heart like Sitka, which has about 8,500 residents.

There’s no written document of Mount Edgecumbe erupting, however he stated there may be Tlingit oral historical past about small eruptions about 800 years in the past.

The final Mount Edgecumbe eruption preserved within the geologic document was about 4,500 years in the past.

There’s additionally proof of a big eruption 13,000 to 14,500 years in the past the place as much as 3 ft (1 meter) of ash was deposited on what’s now Sitka, whereas 98 ft (30 meters) fell on Kruzof Island.

Alaska hopes to recoup losses from canceled oil and gas leases

Alaska hopes to recoup losses from canceled oil and gas leases


FAIRBANKS, Alaska (KTVF) – The State of Alaska has filed suit hoping to recoup losses in revenues stemming from federal cancellation of oil and gas leases on the Arctic National Wildlife Refuge (ANWR).

In a press release Tuesday, the Alaska Attorney General’s office announced the suit, which was filed in the United States Court of Federal Claims. The release mentions nine cancellations on ANWR’s Coastal Plain.

Calling it an effort to hold the U.S. government accountable for the economic impacts of its environmental policies, Attorney General Treg Taylor alleges the federal government is undermining Alaska’s ability to be economically independent.

“The Biden administration’s decisions since day one have been aimed at making the State of Alaska off limits to any resource development to the detriment of Alaska and Alaskans seeking to provide for their families,” said Alaska Attorney General Treg Taylor. “As the rest of the nation celebrates the Fourth of July, the federal government has systematically undermined the State’s ability to maintain its economic independence. This was not what was promised Alaskans at statehood, and why the State must continue to fight.”

“We know these resources can be developed safely and responsibly, and with the support and involvement of the local communities that live within the 1002 Area,” said John Boyle, Commissioner of the Alaska Department of Natural Resources. “The only obstacle is the radical environmentalist agenda of the Biden Administration.”

The release claims Alaska was promised the ability to use resource development to build its economy.

It also says the government’s action cancelling the Coastal Plain leases, which had been approved in 2017 under the Trump Administration, constitutes a breach of contract.

Amid Alaskan Glaciers, a Possible ‘Death Spiral’

Amid Alaskan Glaciers, a Possible ‘Death Spiral’


Since the late 1700s, the Juneau Ice Field, interconnected glaciers that stretch across 1,500 square miles of Alaska and British Columbia, has lost about a quarter of its volume. But it’s an “incredibly worrying” phenomenon that took place between 2010 and 2020 that has scientists especially concerned: The remote swath, which features the famous Mendenhall Glacier, dropped 1.4 cubic miles of ice annually during that decade-long period, double the rate of ice melt before 2010, reports the New York Times. In their study published Tuesday in Nature Communications, researchers add that rates of “area shrinkage” were five times faster from 2015 to 2019 than they were from 1979 to 1990.

The team led by Newcastle University glaciologist Bethan Davies pulled together decades of glacial measurements using aerial views, surveys, maps, and satellite imagery, supplementing that with in-the-field verification and research into tree rings and peat to try to figure out previous environments in the ice field. What they found was that every single one of the area’s 1,050 glaciers receded between 1770 and 2019, with 108 glaciers vanishing altogether; dozens of new lakes formed as a result. Scientists say the melt is affected by tourism; soot from wildfires that lands on the ice and expedites melting; and the wide, flat surface of thinning ice that further exposes it to warming air, among other factors.

Just because Alaska is a far-flung spot for most of the planet’s inhabitants, the glacial melt there matters “tremendously,” per the Times, which notes that “in no other region of the planet are melting glaciers predicted to contribute more to global sea-level rise this century.” Plus, scientists fear that ice fields elsewhere, including in Greenland, Norway, and other Arctic-adjacent locations, could meet the same fate, per Reuters. Global warming will likely continue to further exacerbate the situation, with one climatologist warning of a possible “death spiral” for the glaciers, per the AP. “If we reduce carbon, then we have more hope of retaining these wonderful ice masses,” Davies tells the Times. “The more carbon we put in, the more we risk irreversible, complete removal of them.” (More glacial melt stories.)

What 6 degrees of warming means for a community built on ice

What 6 degrees of warming means for a community built on ice


This story is the first feature in a new Vox special project, Changing With Our Climate, a limited series exploring Indigenous solutions to extreme weather rooted in history — and the future.

When Priscilla Frankson thinks about home, she thinks about ice — thick sea ice stretching out toward the horizon.

Frankson, an Iñupiaq masters student in Tribal Leadership and Governance at Arizona State University, is from Point Hope (Tikiġaq), Alaska, a small city about 125 miles above the Arctic Circle and one of the northernmost communities in the United States.

“For us, the ice is a part of land, even though every single year it changes and it’s always different,” she said. “I think of the way that my boots kind of crackle over the ice, or the different sounds that it makes when there’s a very thin kind of sheet of snow on the top, and how it’s a little bit softer.”

In Point Hope, where summer temperatures rarely break 60 degrees, ice and cold are a part of life. Thick, reliable sea ice is essential for harvesting whales, a key part of the subsistence diets, a lifestyle built around harvesting wild foods for personal and community use, of Point Hope’s Iñupiaq residents.

Growing up, even when temperatures reached 40 below zero, Frankson would bundle up to go play outside in the snow or go hunting on the ice, while whales passed by. And on cold, cloudless nights, the northern lights would be spectacularly clear, flashing and dancing across the sky. It was a sight that Frankson said still seems too incredible to be real — even after years of observing it.

But climate change is threatening all of this.

Alaska is warming up to three times faster than the rest of the world, and the Arctic is warming nearly double that. Alaska’s North Slope, where Point Hope is located, saw an average annual temperature increase of 6 degrees since 1971. Since 1970, the US as a whole has warmed by 2.6 degrees.

Although the difference between, say, a day that is 0 degrees and one that is 5 degrees may seem like no big deal, the impact of these rising averages is immense.

Sea ice is forming later in the year than usual and is not as predictable as it used to be. As the permafrost thaws, siġlauqs — the traditional ice cellars carved into the land — are caving in or flooding. The animals that people rely on for food and goods — whales, fish, caribou — are also growing harder to find.

Despite the challenges, Frankson, who researches the social impact of declining caribou populations, says that Iñupiaq people are not going to change their entire way of life, but instead are making small adjustments to changing conditions. “We’re not scared enough to stop hunting, we’re not scared enough to stop going out on the ice, we’re not scared enough to do any of this,” she said. “We’re just learning how to adapt, as we always have.”

To adapt to the warming climate, Indigenous people in Alaska are relying on their deep understanding and respect for the land, a kind of humility developed over countless generations. “You can’t really change the Arctic,” Frankson said. “You can only change with the Arctic.”

Yes, daily life in Alaska — with its northern lights, its dependence on ice and the movement of caribou — may feel unrelatable. But this way of living in tune with the environment and gracefully adapting to a changing climate is becoming increasingly essential for the rest of the country. The strategies that Indigenous people in Alaska are developing show that sometimes the best forms of climate adaptation are achievable, local solutions.

Generations of extreme conditions have equipped Alaska Natives with the willingness and ability to embrace this kind of adaptation. As the impacts of climate change grow increasingly severe in the rest of the country, we could all learn from that.

Swimming may not seem like an adaptation to global warming. But in Alaska, it is.

Hundreds of miles south of Point Hope, in Bethel, Alaska, the Kuskokwim River is the heart of the community, providing food, transportation, employment, and community throughout the year.

The only way to get to Bethel is by plane, which can be very expensive, or by the river. In the winter, snow machines zip through town, heading up and down the frozen river to the dozens of villages that depend on Bethel for food, supplies, health care, and much more. In the summer, people travel by boat to spend days at their fish camps on the river, smoking salmon to eat throughout the rest of the year. In between, when the ice is forming or beginning to break up, the river can be dangerous: too frozen for boats, but too unstable for snow machines and cars.

“You can’t really change the Arctic. You can only change with the Arctic.”

Lately, those shoulder seasons have been shifting, extending, and becoming terrifyingly unpredictable.

Every year, flooding and erosion get worse, fish are dying, and the winter ice is becoming more dangerous. Kevin Whitworth, the executive director of the Kuskokwim River Inter-Tribal Fish Commission, says declining salmon populations are especially concerning. “It’s hard times,” he said. “Our people are subsistence-based people. They’re not economy-based people. They rely on the river as their grocery store. Their life is the river.”

According to the Federal Subsistence Management Program, rural Alaskans harvest 295 pounds of wild food per person, more than the 255 pounds of domestic meat, fish, and poultry that the average American consumes per year. Fifty-six percent of the statewide subsistence harvest is made up of fish. Beyond its cultural and community importance, subsistence is crucial for Alaska Natives because of the high cost of groceries. In a study of 261 urban communities across the country, the Council for Community and Economic Research found that the three most expensive places for groceries were Juneau, Fairbanks, and Anchorage. Prices in more remote communities like Bethel are often even higher.

Salmon’s drastic decline can be attributed to a number of causes, including warming waters and increased offshore trawling. Every year, ocean trawlers fishing primarily for pollock catch, kill, and discard about 141 million pounds of salmon, halibut, and other species, an extraordinarily wasteful practice that Indigenous people and other groups in Alaska have been rallying against. Meanwhile, communities upriver are severely limited in the number of salmon they can take from the river. “Right now, the salmon are crashing and we’re seeing big changes with the climate,” Whitworth says.

Bethel Vice Mayor Sophie Swope, who also sits on the Orutsararmiut Native tribal council, says that river conditions have become more dangerous for fishing and travel. “It used to be pretty dependable that you could just go drive out during the winter and it would be fine and safe,” Swope said. “Now, you have to keep an ear out for what the river conditions are.”

Whitworth, who is Athabascan from McGrath, says that because of salmon’s increasing scarcity, people are taking greater risks to get fish even though the river ice forms later in the season and is less reliable, leading to accidents and drownings.

So, facing declining salmon populations and a dangerous river, Indigenous people in the region are shifting their norms, too. While chinook and chum salmon are restricted, sockeye salmon, a less traditionally popular and available fish, has become an increasingly viable alternative.

Chinook has been a staple of Indigenous subsistence diets for generations, but people are doing what they must to use what is available now. Traditional salmon fishing techniques make it hard to separate different species of salmon, so Whitworth and the Kuskokwim River Inter-Tribal Fish Commission have been encouraging local fishers to use dip nets, large circular nets that allow people to target sockeye.

In the commission’s 2023 end-of-season report, sockeye made up about 40 percent of the estimated total salmon harvest on the lower Kuskokwim, a number that Whitworth says is much higher than it used to be.

As warming continues to impact the river, the local community has also been taking steps to protect its people.

In 2014, Yup’ik elder Beverly Hoffman and others finally succeeded in a decades-long effort to build a community pool in Bethel, which is now a resource for people throughout the region to learn how to swim, preparing them for an increasingly unpredictable river. Hoffman and others recognize that they cannot control the river, but they can help prepare the community to survive its dangers.

Swimming lessons and dip nets might sound like tiny changes in the face of global climate trends, but these are the kinds of local adaptations that will help communities thrive in a warming world. Outside of Alaska, planting trees to create more shade in urban heat islands or hiring more lifeguards for public pools could have a similar impact.

But these solutions are within reach and meaningful; they literally save lives.

Such approachable adaptations mean understanding that although we have a limited ability to change the climate, there are many more options to change our own behavior.

“This is what Indigenous knowledge is

As temperatures continue to rise, Alaska Natives are turning to intergenerational knowledge and community observations to build a wealth of data that they hope will urge non-Indigenous decision-makers to listen to what they have to say.

In Unalaska, the largest city in the Aleutian Chain, the Qawalangin Tribe is gathering community feedback on climate change and what the people are experiencing. The tribe will then use these observations to help develop its climate resilience plans, which include culture camps with traditional dances and classes on kayak making, traditional food nights, and water quality testing programs.

Vera Metcalf is the executive director of the Eskimo Walrus Commission, which represents 19 coastal communities. Metcalf says that Indigenous walrus hunters have adapted to climate change by participating in research projects led by agencies like the US Fish and Wildlife Service. “In the past, we were largely ignored in research occurring in our homeland and waters,” she said. “When you combine the two ways of thinking, it really becomes a rich resource of information.”

Changing With Our Climate: A limited series exploring Indigenous solutions to extreme weather rooted in history — and the future

There’s no easy fix for the planet, but Indigenous people have simple solutions rooted in the depth of their knowledge. This story is the first installment of a new Vox series exploring frameworks for responding to extreme weather and the climate crisis. Every month through October, we’ll be publishing a new feature that centers an Indigenous community responding to various aspects of climate disasters, from major storms like hurricanes and typhoons, to extreme heat, rising seas, wildfires, and spreading aridity.

Roberta Tuurraq Glenn-Borade, Iñupiaq from Utqiaġvik, is the project coordinator and community liaison at the Alaska Arctic Observatory and Knowledge Hub, where she works with observers from four communities in the Alaskan Arctic.

Community observers share details like air temperature, wind speed, ice conditions, and animal observations, sometimes sending in photos of animals being harvested. Glenn-Borade and her team then take this data and share it with agencies like the US National Weather Service, which releases forecasts for the region. Glenn-Borade says that, historically, these forecasts prioritized larger ships offshore rather than Indigenous people living on the coast and hopes that using local observations will lead to better forecasts for Indigenous communities. “That kind of foresight of what the conditions will be can really make a difference between life or death,” she said.

Glenn-Borade also says this kind of local observation provides invaluable historical context about how the coast and the ice have changed over the years, what is within normal ranges, and what is unexpected.

“That’s what Indigenous knowledge is,” she said. “It is constant tracking and understanding and monitoring what’s going on and being prepared to respond on the fly.”

As the world warms, these examples from Alaska offer a warning that we can’t simply do everything the way we used to. Saudi Arabia, for example, can no longer ignore the deadly impacts heat is having on Hajj. Places like the Pacific Northwest can no longer count on mild summers and will save lives by investing in cooling infrastructure. But they also offer hope that if we can shift away from trying to change the environment to suit us, instead of the other way around, there may be a chance of finding creative, unexpected ways of changing with our climate.

When I spoke with Glenn-Borade recently, she told me she and her people are proud “that we’re still here. We’re not going to die off. Our languages aren’t going to die off. We will adapt. We’ll continue to adapt our lifestyles as the environment changes.”
