Katla Update

Katla (Southern Iceland): An increased number of small earthquakes, up to magnitude 2.7, has been occurring near the surface or at very shallow depths under Katla’s ice cap since yesterday.

These quakes are most likely related to weight adjustments of the thick ice cap during the ongoing seasonal melting and unlikely to represent a true seismic swarm caused by (internal) volcanic activity.

In the meanwhile, the alert (uncertainty level) for the areas around rivers from the Mýrdalsjökull glacier has been cancelled by Iceland authorities.

“Uncertainty Level” for Katla Volcano

The government of Iceland has raised the level of concern for Katla after swarm of earthquakes.

Katla Swarm


Is Katla Ready To Blow?

Haraldur Sigurdsson charts the skyrocketing number of quakes (at Katla in Iceland) since 1990 and thinks “…it is unlikely that the quakes are related to melting of ice due to the glacier. Hence, he says that possibly the quakes are related to geothermal heat under the ice. Haraldur Sigurdsson concludes by saying that Katla continues to cause nervousness among all.”

In 2010 the eruption of Eyjafjallajökull in Iceland closed the airspace of Europe. Katla is immensely bigger. It could be devastating!

UPDATE: The Three Rivers quake is on the south shore line of Pauline Lake.

Paulina Lake is one of the twin crater lakes (the other being East Lake), located 6,350 feet (1,940 m) above sea level in Newberry Crater within the caldera of Newberry Volcano, about 25 miles south of Bend, Oregon.


Katla Becoming Active, Again!

Katla Erupts? No!

The National, the Abu Dhabi Media company’s first English-language publication, has set a new standard of quality English-language journalism in the Middle East claims this as new, but it’s not current and not Katla! It’s probably an eruption at Grímsvötn volcano at approximately 17:30 UTC, May 21st 2011.

Iceland: Katla Rumbling?

Seismologists are nervously watching rumblings beneath Katla, a volcano on the southern edge of the north Atlantic island nation, which could mean an eruption is imminent.

Katla’s Activity Worrying Scientists

“Katla has now been receiving international attention, as rumbles in the area – and the potential magnitude of its pending eruption – could prove even more disruptive than Eyjafjallajökull.”

Indeed!

We Are Monitoring Katla

Quake-hit Iceland volcano Katla shows strengthening signs of eruption. Katla registered a 3.2 quake yesterday amid increasing signs that a full-scale eruption is near.

The latest quake follows a week of increasing activity with official reports of harmonic tremors and earthquake swarms.


Activity Up In Katla!
