Volcano WARNING: THESE volcanoes are most ‘OVERDUE’ for eruption and pose greatest threat

Matthew Robinson — Tue, 12 Jun 2018 18:02:22 +0000

FOLLOWING the eruption of Volcán de Fuego in Guatemala which has left at least 110 people dead and around 200 missing, and the eruption of Hawaii’s Kilauea volcano which has destroyed hundreds of homes, fears have risen over the status of other “overdue” volcanoes.

Volcanic eruptions are nearly impossible to predict, but scientists are able to estimate which volcanoes are more “overdue” than others based on their eruption history.

Ben Edwards, a professor of earth sciences at Dickinson College, said: “Overdue in human terms is very different than overdue in geologic terms.

“For example, given the observation that Yellowstone has a big eruption about every 600,000 to 700,000 years, it is probable that it will have another large eruption in the next 100,000.

“That seems like a lot of time to humans, but from the perspective of a planet that is 4.5billion years old, a hundred thousand years in the future is relatively soon.”

He warned an eruption at the Yellowstone Caldera would be devastating, with lava flows extending between 50 and 65km.

Tracy K.P. Gregg, a geologist at the University at Buffalo, also noted studying volcanic history provides scientists with some indication of which volcanoes are more “overdue” than others.

She said: “We learn about a volcano’s likely future behaviour by examining its past behaviour: We look at how often it has erupted in the past, and how big those eruptions were.

“The simplest thing to do is to assume that the volcano will continue to behave in the same way it always has.”

Mount Rainier poses a serious threat to the 3.7m residents in the Seattle area

However she warned little is known about the majority of the 550 active land volcanoes, and only those located near densely populated areas in first-world countries are regularly monitored.

She said: “Remember how Pinatubo erupted in the Philippines in 1991?

“Until that volcano began showing signs of unrest – typically small earthquakes that are caused by magma moving beneath the volcano – no one had conducted a detailed geologic investigation of the volcano’s past, so we didn’t know what the volcano had done before.

“There simply isn’t the time, people and money to monitor and study every active volcano.”

She also warned many of the volcanoes which pose the greatest threat are those receiving the least monitoring, including Iwo Jima near Japan and Mount Tambora in Indonesia.

In addition, Ms Gregg is concerned about Mount Rainier in Washington State, due to a large amount of glacial ice and the threat it poses to the 3.7million residents in the Seattle area and the Puyallup River valley.

She said: ”It seems to have experienced potentially damaging eruptions every couple of thousands of years and its last hazardous eruption was about 2,200 years ago.

“However, even a small eruption of Rainier could cause significant damage to property.”

Yet Mr Edwards expressed his concern about Etna in Sicily, Veniaminof in Alaska, Klyuchevskoy in Russia, Villarrica and Llaima in Chile, and Katla and Hekla in Iceland.

He said: “These are all snow/ice-covered volcanoes that have a reasonable probability of erupting in the next 10 to 50 years.

“You can bet that if any do erupt, I will do my best to head their way to study volcano-ice interactions!”

Despite the challenges scientists face in predicting volcanic eruptions, the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) Decade Volcano Programme has identified the volcanoes which pose the greatest threat.

Their list is based not simply on which volcanoes are most likely to erupt, but rather on which volcanoes are located within highly populated regions and also capable of producing lethal volcanic eruptions including lava flows, pyroclastic flows, lahars and ash falls.

The IAVCEI Decade Volcano Programme’s top 16 volcanoes are as follows:

Avachinsky-Koryaksky in Kamchatka, Russia
Colima in Jalisco, Mexico
Galeras in Nariño, Colombia
Mauna Loa in Hawaii, United States
Mount Etna in Sicily, Italy
Mount Merapi in Central Java, Indonesia
Mount Nyiragongo in North Kivu, Democratic Republic of the Congo
Mount Rainier, in Washington, United States
Mount Vesuvius in Campania, Italy
Mount Unzen in Nagasaki/Kumamoto, Japan
Sakurajima, in Kagoshima, Japan
Santa María in Quetzaltenango, Guatemala
Santorini in the South Aegean, Greece
Taal Volcano in Calabarzon, Philippines
Teide in Canary Islands, Spain
Ulawun in East New Britain/West New Britain, Papua New Guinea

‘Yellowstone is RUMBLING again!’ Super volcano eruption fears grow as mini quakes hit

Sean Martin — Tue, 13 Mar 2018 09:03:10 +0000

YELLOWSTONE is showing signs of activity once more as earthquakes beneath the potentially catastrophic volcano continue to strike.

In the last week, there have been four tremors in and around the Yellowstone volcano.

Minor earthquakes occur in the Yellowstone area around 50 times a week.

The most recent quake came on March 11 when a small 1.5 tremor took place beneath the surface.

The strongest one, a 1.8 magnitude earthquake, came just hours before this, and people are concerned that Yellowstone could be about to blow.

Worried social media users took to Twitter to voice their fears.

One person wrote on Twitter: “Pray to Yellowstone caldera. We can end it all.”

Joey Brooklyn said: “Yellowstone is rumbling again”.

RyGuy said on the social media site: “Yellowstone’s gonna blow up and get us all”.

Yellowstone will erupt one day

Meteorologist Tom Skilling moved to calm any nerves, and said this is actually an unusually quiet week for the supervolcano.

He wrote on the WGN news website: “Minor earthquakes occur in the Yellowstone area 50 or more times per week, but a major eruption is not expected in the foreseeable future.”

The Yellowstone Caldera supervolcano last erupted 700,000 years ago but experts say it should blow every one million years or so.

If the Wyoming volcano were to erupt an estimated 87,000 people would be killed immediately and two-thirds of the USA would immediately be made uninhabitable.

The large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter”.

The massive eruption could be a staggering 6,000 times as powerful as the one from Washington’s Mount St Helens in 1980 which killed 57 people and deposited ash in 11 different states and five Canadian provinces.

If the volcano explodes, a climate shift would ensue as the volcano would spew massive amounts of sulphur dioxide into the atmosphere, which can form a sulphur aerosol that reflects and absorbs sunlight.

Fears Yellowstone volcano ‘IS going to blow’ as earthquakes strike near crater

Sean Martin — Thu, 08 Feb 2018 11:08:21 +0000

A SPATE of earthquakes near to the Yellowstone caldera in the last few days has sparked fears the potentially catastrophic volcano is about to blow.

Three earthquakes in the last seven days around the Yellowstone Caldera has triggered concern that the volcano could erupt.

A 1.6 magnitude quake five days ago was quickly followed by a tremor of the same magnitude on the same day.

Two days later, another 1.6 magnitude tremor struck the region, taking the total to 11 earthquakes in the last month.

Typically, when there are tremors around a volcano, it is a sign the magma is recharging and could lead to an explosion.

Earthquakes have rocked the Yellowstone Caldera Residents near to the volcano have taken to social media to voice their concerns that the volcano could blow.

Mary Faith Suarez said: “It’s getting a bit unnerving.”

Catalina Tucker said: “All I can say is if I lived anywhere near this monster I would definitely be moving somewhere else. This volcano is so dangerous and it IS gonna blow.”

An eruption at Yellowstone could wipe out America.

However, experts say an earthquake swarm is not necessarily an indication that a volcano will erupt.

Jamie Farrell at the University of Utah in Salt Lake City has said: “Earthquake swarms are fairly common in Yellowstone.

“There is no indication that this swarm is related to magma moving through the shallow crust.”

The Yellowstone Caldera supervolcano last erupted 70,000 years ago.

If the volcano were to erupt it would kill an estimated 87,000 people immediately and make two-thirds of the USA immediately uninhabitable.

The large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter”.
