Katla Update: 2 Earthquakes In 3 Hour

The earthquakes at the Katla volcano site appear to possibly be increasing in frequency, according to a report at the Modern Survival Blog.  The two most recent earthquakes occurred within 3 hours of each other on 21 May, the report says.

“It may be a precursor warning that an eruption is about to happen.”

“The earthquakes at the Katla volcano site appear to possibly be increasing in frequency as of this moment (time will tell however). Since May 17 there have been four earthquakes at or very near Katla, while a 5th just on the edge of the Myrdalsjokull glacier,” the post says.

“Although 4 or 5 earthquakes at the volcano site in 4 days does not indicate a drastic change in pattern, the interesting notation at the moment is the fact that the two most recent earthquakes occurred within 3 hours of each other on 21 May, 2010, at depths of 5km and 13km. That in itself is an increase in occurrence. It may be an anomaly, but it justifies keeping one eye on Katla, the big sister of Eyjafjallajokull.”

“One type of volcanic earthquake may indicate that changes are occurring due to magma moving in to an area of the rock which changes the pressure around it. At some point, the rock will break or move. If this type of earthquake becomes frequent, and a lot of earthquakes begin occurring or swarming (Earthquake swarms are when we suddenly start seeing clusters of earthquakes in the same general area over a relatively short period of time), it may be a precursor warning that an eruption is about to happen.”

“What we are seeing at Katla, in my opinion is NOT cause for immediate alarm, but it is noteworthy to observe this recent activity and to stay up to date with what is happening there.”
