Katla volcano (Iceland): small earthquake swarm, but not likely indicator of activity in the near future

Tuesday May 29, 2012 10:09 AM | BY: T

Small earthquake swarm at Katla volcano during 28-29 May 2012 (Icelandic Met Office)
Small earthquake swarm at Katla volcano during 28-29 May 2012 (Icelandic Met Office)
A swarm of 14 small to very small mostly very shallow quakes occurred at Katla volcano yesterday and today. Epicenter depths were reported between 0.1 and 12.2 km. Judging from the depth and magnitude of the quakes, the most likely cause for the seismic swarm are adjustments of the hydrothermal system under the icecap, and probably not magmatic intrusions (which would be possible indicators of a future new eruption).

Recommendation:
A very interesting article about the unrest (which is almost normal for volcanoes as active as Katla) at the Icelandic volcano was published at volcanocafe under the title What's going on at Katla.
