The Grímsvötn is located in a remote area of central Iceland.
Iceland has raised its eruption alert level for the country's most active volcano, Grímsvötn, after several recent earthquakes.

Authorities said on Monday that one of the nearby quakes was recorded at a magnitude of 3.6.

But although seismic activity had increased, officials say they have not detected any tremors that have caused a surge in underground magma.

The volcano last erupted in 2011, generating a major ash cloud that partially disrupted air traffic across Europe and cancelled 900 flights.

Comment: On the 4th December, Volcano Discovery reported on the glacial flooding at Grimsvötn:
The meltwater rate has been increasing since the last update. The IMO's hydrologists measured 1600 cubic meters per second at 10:15 and 12:20 local time today in Gígjukvísl.

The latest measurements confirm estimated forecasts and if continue to be in line with them, the glacial flood will likely reach its peak on Sunday. Based on the latest data, the maximum discharge rate is expected to be about 4000 m3/s.

The ice sheet has continued to drop and reached already about 27 m in total subsidence.

Higher-than-usual gas emissions levels have been detected at the glacier rim of the volcano.

Recent eruptions at the volcano occurred every 5-10 years and based on current measurements and observations, volcanologists agree that an impending eruption is highly expected.
The following tweets, translated by Twitter, show the flooding, deformation, and melt at Grimsvötn volcano:
'The water that was under the glacier that covers the volcano Grímsvötn , began to come out. A Jökulhlaup began to be created that rose more than 4 m, it is a matter of days before we begin to see columns of steam and ash in the main crater.'


1st Tweet: 'The last flyby of the ice cap at Vatnajökull shows that part of the ice sheet covering the volcano's craters Grímsvötn is collapsing. The volcanic danger traffic light has been raised to orange due to the recent earthquakes and collapses.'

2nd post: 'The boiler limits of Grímsvötn also show shear and collapse effects. After the water comes out, the volcanic system is losing pressure which may generate an eruption in the next few days, creating plumes of steam and ash.'


Whilst Grímsvötn volcano may be considered to erupt with some regularity, this comes amidst an uptick of seismic and volcanic activity elsewhere in Iceland, as well as across much of the planet: Also check out SOTT radio's: As well as SOTTs monthly documentary SOTT Earth Changes Summary - October 2021: Extreme Weather, Planetary Upheaval, Meteor Fireballs

Residents flee massive ash cloud from erupting Semeru volcano in Indonesia - At least 22 dead (UPDATE)

Mount Semeru: Indonesia volcano erupts sending ash '40,000ft into sky' as locals flee

Mount Semeru: Indonesia volcano erupts sending ash '40,000ft into sky' as locals flee
A volcano erupted on the Indonesian island of Java on Saturday, reportedly obscuring the sun with a massive cloud of ash, and sending locals into a panic.

A clip on social media has captured people, who live at the foot of Semeru volcano, fleeing in fear ahead of a cloud of black ash descending from the 3,676-meter-tall mountain.

The author of the footage is heard shouting "Allahu Akbar" (God is great) in face of this truly apocalyptic sight.


Comment: Update: TASS reported on December 6:
At least 22 people died and 20 more are reported missing after Mount Semeru, a volcano on Indonesia's Java island, erupted, a spokesman for the local emergencies agencies told the DetikNews portal on Monday.

"Rescuers found more dead bodies, so, the overall death toll has reached 22," he said, adding that five bodies have not yet been identified.


The local authorities said earlier that at least 27 local residents were reported missing after the volcano spewed ash on December 4. More than 50 people were injured.

Semeru, the highest mount on Java, is one of Indonesia's nearly 130 active volcanoes.

Scientists with the Canary Islands' volcanology institute, Involcan, inspect as the lava flows from a volcano on the Canary island of La Palma, Spain, Saturday, Oct. 30, 2021.
As a volcano continues to spew hot lava on a little island in Spain, scientists from around the world are racing to the area to study and learn about the rare eruption.

The Cumbre Vieja volcano has been erupting since September on La Palma, a small island in the Canary Islands of Spain. So far, nearly 1,150 buildings and surrounding land has been destroyed, according to Reuters.

According to an analysis by The Associated Press, volcanic eruptions to this degree are incredibly rare, occurring once, or at most twice, in a generation in the Canary Islands. Parts of the Canary Islands are actually still growing, as magma accumulates underneath and, as is happening in La Palma, lava peninsulas are forming beyond the coastline.

The Smithsonian Institution estimates there are currently 48 volcanoes currently in "continuing eruption status" worldwide.

In order to help ease the devastation the Cumbre Vieja volcano continues to cause, scientists are flocking to La Palma to study the eruption up close. They're hoping to learn how volcanoes form, develop and how and when they stop erupting.

FILE - The crater lake formed after Mt. Pinatubo erupted in 1991, shown in this file photo, has become a major attraction for outdoor enthusiasts, with trails opened in Tarlac and Zambales provinces.
A "weak explosion" was recorded at Mt. Pinatubo on Tuesday, said the Philippine Institute of Volcanology and Seismology.

In its latest bulletin, Phivolcs said the explosion was recorded between 12:09 p.m. and 12:13 p.m.

"The event produced a plume that was detected by the Himawari-8 Satellite and reported to Phivolcs by the Tokyo Volcanic Ash Advisory Center," said Phivolcs.

'Volcanic winter' likely contributed to ecological catastrophe 250 million years ago

A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago.Its analysis of minerals in southern China indicate that volcano eruptions produced a "volcanic winter" that drastically lowered earth's temperatures--a change that added to the environmental effects resulting from other phenomena at the time.

The research, which appears in the journal Science Advances, examined the end-Permian mass extinction (EPME), which was the most severe extinction event in the past 500 million years, wiping out 80 to 90 percent of species on land and in the sea.

"As we look closer at the geologic record at the time of the great extinction, we are finding that the end-Permian global environmental disaster may have had multiple causes among marine and non-marine species," says Michael Rampino, a professor in New York University's Department of Biology and one of the authors of the paper.

For decades, scientists have investigated what could have caused this global ecological catastrophe, with many pointing to the spread of vast floods of lava across what is known as the Siberian Traps--a large region of volcanic rock in the Russian province of Siberia. These eruptions caused environmental stresses, including severe global warming from volcanic releases of carbon dioxide and related reduction in oxygenation of ocean waters--the latter causing the suffocation of marine life.

Climate doom pantomime at Glasgow

Think of Glasgow as a costume party for the Uber rich and it all makes sense.

Everyone gets to hobnob, dress up in a Superhero prophet-of-doom outfit and pretend to save the world.

When the richest people in the world turn up, with PM's and Presidents, and even the Royals do live photo tweets — you know the dry UN science conference has turned into the unmissable Olympics of Social Events. Just being there is the fashion statement of the year.

The biggest underwater volcanic eruption Japan has seen since the end of WWII has left shores covered in pumice stone. In one video, stones are seen covering the waves, while images show fishing ports inundated with volcanic rock.

The volcano, Fukutoku-Okanoba, is situated on the Ogasawara island chain, about 800 miles from Tokyo. It sits about 25 meters below the surface of the sea.

It exploded on August 13, with images showing a huge plume of gas rising out of the sea, into the air. Satellite images from NASA showed a huge bright plume streaming from the vent, stretching for miles.

In a NASA statement, Andrew Tupper, a meteorologist with Natural Hazards Consulting, said: "What was remarkable about this eruption is that it went straight from being a submarine event to an eruption cloud reaching the lower boundary of the stratosphere. That is not very common for this type of volcano. We normally see lower-level plumes from submarine eruptions."

Mud volcano Shugo erupts in Krasnodar Krai, Russia

erupts
Not far from the village of Varenikovskaya, the active mud volcano Shugo began to erupt. Its height reaches 163 meters. It is the largest in the Kerch-Taman volcanic region.

The volcano is very dangerous. Hot mud flies out of its craters, which scatters several tens of meters. But now the craters are inactive: rare and unstable ejections can be observed.

According to the head of the Crimean region, Sergei Les, the volcano has been active for many years. His incessant work is associated with the growth of the Caucasian mountain system.

Volcanic mud, which contains bromine and iodine, is regularly replenished. Now Shugo is under protection and will be closed for tourists for the time being for safety reasons.
