Harmonic tremors appear to be increasing under Katla

27 Jul 11 - A swarm of earthquakes struck the 9-mile wide volcano, a week after geophysicists warned of an “imminent danger” of an eruption on the island.

The volcano is capable of producing four times the ash of Iceland’s last eruption in May.

Earthquake activity around Katla has been steadily gaining strength over the past five weeks, and observers believe ‘unusual’ magma movement deep beneath Katla could signal the early stages of activity that could lead to a huge explosion.

Last year's eruption of Eyjafjallajökull triggered the mass closure of European air space as the resulting ash cloud was thought to pose a danger to aircraft engines.

In the past 1,000 years, all three known eruptions of Eyjafjallajökull have triggered subsequent Katla eruptions.

"I've watched this page ( ) ever since last year's eruption of it's neighbor, when the Icelandic government warned of Katla's eminent eruption - "not if, but when." says Thomas.

"I think I am as much concerned with the lack of news about this activity as I am about listening to someone referred to as "the science guy" on a network saying that the geology of Venus can be applied to the geology of the Earth in explaining "global warming." 

"If that is science, it wasn't taught when I was in school, and you can't get there by extrapolating what I was taught."
