Mýrdalsjökull Ice Cap: Iceland's Katla Volcano is 'due a big eruption'

After and before shot shows how ice cap has changed.
A volcano sitting beneath Iceland's Mýrdalsjökull ice cap is due for a "big" eruption, Nasa has said. Satellite images showing Mýrdalsjökull reveal the ice cap has shrunk dramatically over the last 30 years, and experts believe this is a result of recent volcanic episodes.


Comment: Well, it's nice to see the 'experts' didn't blame the shrinkage on 'global warming'.


The images, from Nasa's Earth Observatory, show before and after photos of the ice cap - the first from September 2014, the second from September 1986.

More than half of Iceland's ice caps and glaciers sit either directly above or near active volcanoes, meaning fire and ice often unite.

New eruption has begun at Alaska's Pavlof Volcano

Alaska's most active volcano is spitting lava into the air and producing an ash cloud at low elevations. But unlike Kilauea Volcano on Hawaii's Big Island, where there's been spectacular images of lava encroaching on a community and burning a home, there's no property at risk in Alaska because of the eruption of Pavlof Volcano.

The 8,262-foot Pavlof Volcano is located in a relatively uninhabited area about 625 miles southwest of Anchorage on the Alaska Peninsula. The closest community is about 40 miles away.

Observers from that community, Cold Bay, reported seeing dark snow on the surface of the volcano Wednesday, indicating an eruption has started. The eruption intensified that afternoon and continued through the week, David Schneider, a geophysicist with the U.S. Geological Survey and the Alaska Volcano Observatory, said Friday.

Among the observations by volcanologists conducting weekend inspections in the area around Costa Rica's Turrialba Volcano were craters in the earth measuring up to one meter in diameter - the result of rocks shooting out from the volcano.

Experts from the National Seismological Network (RSN) and the Volcanological and Seismological Observatory of Costa Rica (OVSICORI) conducted the inspections in light of significant activity at the volcano that started last week.

RSN volcanologist Gino González Ilama said the areas of impact are located on the south side of the volcano and cover 80 percent of the slope up to 400 meters from the volcano's crater.

"We observed the impact of volcanic rock that had caused several craters on the ground. We believe the rocks were shot out of the volcano at speeds greater than 100 kilometers per hour, and this proves there is strong activity inside," González said.

Steam and ash spews from a vent inside the crater of the Turrialba volcano in Costa Rica.
The biggest eruption in a century at a volcano in Costa Rica has rained ash over the Central American country and prompted authorities to evacuate some communities.

Emergency services and scientists remained on high alert on Friday after the overnight explosion at the Turrialba volcano, close to the capital San Jose.

Volcanologist Gino Gonzalez said that the volcano had been rumbling and producing seismic activity since Wednesday evening.

He said the explosion caused the side of the crater to collapse, and ashfall was recorded in four provinces.

Idiocracy: Japan reacts to Fukishima disaster by re-opening nuclear plant right next to active volcano

D'oh!

Scientists warned that an earthquake could take out Fukushima. The Japanese ignored the warning ... and even tore down the natural seawall which protected Fukushima from tidal waves.

Fukushima is getting worse. And see this and this.

Have the Japanese learned their lesson? Are they decommissioning nuclear plants which are built in dangerous environments?

Of course not!

Instead, they're re-starting a nuclear plant near a volcano which is about to blow ...

A month ago, there was an eruption at Mt. Ontake:

Lava stream threatening homes and inching closer to road on Hawaii's Big Island

In this Oct. 22, 2014 photo provided by the U.S. Geological Survey, geologists walk over the surface of the flow to track surface breakouts along a portion of the flow margin, about a kilometer upslope of the flow front. A 13-mile finger of lava from Kilauea Volcano has started to again move quickly, and could hit a secondary road sometime Friday, Oct. 24, 2014. Officials on Hawaii's Big Island won't start evacuating people until the lava flow is within three to five days of affecting Pahoa residents.
A growing lava stream threatening homes and inching closer to a rural road on Hawaii's Big Island oozed forward in fits and starts this week, frustrating some residents but giving officials a window of time to prepare. The narrow, leading edge of the lava flow is now just 250 yards from the one-lane country road, which has been closed. Crews are working on an alternate route for remote communities in the Puna district in case the lava crosses a major thoroughfare.

The lava sped up over the past few days, advancing nearly 460 yards from Thursday morning to Friday, but it slowed again Friday morning, officials said. The flow's fitful nature is taking a toll on some Big Island residents, who got a brief reprieve from the advancing molten stream only to have to raise their guard again.

"This stop-and-go - it's going to be very frustrating for our residents," said Darryl Oliveira, director of Hawaii County Civil Defense. "It raises the anxiety level. It raises the concern."

Restive Mayon volcano showing new signs of activity with quakes and rock fall


Mayon
Restive Mayon Volcano showed new signs of activity with four volcanic quakes and one rockfall in the last 24 hours, the Philippine Institute of Volcanology and Seismology said Friday. In its 8 a.m. update, Phivolcs also observed a moderate emission of white steam plumes drifting southwest. However, it said there was no crater glow observed Thursday night.

These activities show Mayon remains "in a state of unrest due to the movement of potentially eruptible magma," it added. Phivolcs said Mayon's alert level remains at "3," meaning "magma is at the crater and that hazardous eruption is possible within weeks."

More than 12,000 families living in Mayon's danger zone had been evacuated since Phivolcs raised the alert level at the volcano in mid-September.

Japan warns of possible Mt. Ioyama eruption near nuclear plant

Mt. Ioyama
Japan warned today that a volcano in southern Japan located roughly 64 km (40 miles) from a nuclear plant was showing signs of increased activity that could possibly lead to a small-scale eruption and warned people to stay away from the summit.

The warning comes nearly a month after another volcano, Mt Ontake, erupted suddenly when crowded with hikers, killing 57 people in Japan's worst volcanic disaster in nearly 90 years. Ioyama, a mountain on the southwestern island of Kyushu, has been shaken by small tremors and other signs of rising volcanic activity recently, including a tremor lasting as long as seven minutes, an official at the Japan Meteorological Agency's volcano division said.

"There is an increase in activity that under certain circumstances could even lead to a small scale eruption, but it is not in danger of an imminent, major eruption," the official said.

The warning level on the mountain has been raised from the lowest possible level, normal, to the second lowest, which means that the area around the crater is dangerous, he added.

Ioyama lies in the volcanically active Kirishima mountain range and is roughly 64 km from the Sendai nuclear plant run by Kyushu Electric Power Co, which the Japanese government wants to restart even though the public remains opposed to nuclear power following the Fukushima crisis.

Colombia-Ecuador border earthquake sparking concern of possible imminent volcanic eruption

Authorities in southwestern Colombia have raised alert levels on Tuesday after a 5.6M earthquake hit the border region, raising concerns that two nearby volcanoes might erupt in a matter of days. Colombia's Geological Service have changed the alert level of two volcanoes from yellow to orange. The two volcanoes are Cerro Negro and Chiles, both active on Colombia's southern border with Ecuador.

The orange alert level is defined by the Geological Service as "probable eruption in term of days to weeks." The earthquake that hit the border region caused a scare on both side of the border.

Officials in the Colombian town of Cumbal, near the quake's epicenter, were quoted as saying by The Associated Press that they formed an emergency committee to survey possible damage. But so far, there were no reports of injuries in the town of 36,000 residents, the majority of them members of an indigenous tribe.

"It was really strong, every house" felt it, Jose Diomedes Juezpesan, the town's top official, told AP. If the volcanoes are to erupt, it will mostly affect the state Nariño. Local state government have started to take security measures in order prevent tragedies.

Colombia orders evacuation of around 12,000 people amid fears of volcanic eruptions

Authorities in southwest Colombia ordered the evacuation of around 12,000 people living near the Chiles and Cerro Negro volcanoes on the border with Ecuador, amid fears that recent volcanic activity may result in an eruption.

On Tuesday, Colombia's Geological Service have changed the alert level of two volcanoes from yellow to orange.

48 hours later, it was followed up by the National Disaster Risk Management Unit's (UNGRD) decision to evacuate more than 3,500 families belonging to indigenous reserves of Chiles , Panam and Mayasquer.

According to Carlos Ivan Marquez, the director of the UNGRD, the authorities set up an incident command post in the town of Cumbal where they have delivered 3,000 tents for the people in temporary shelters.

"In accord with the forecast given to us by the Geological Service, the change of alert level from yellow to orange means anticipated eruptions in the coming days or weeks," Marquez told the media.

If the volcanoes are to erupt, it will mostly affect the state Nariño. Local state government have started to take security measures in order prevent tragedies.
