Minor Glacial Burst in South Iceland Volcano Katla

A small glacial burst occurred in the volcano Katla, which lies underneath the Mýrdalsjökull icecap in south Iceland, on April 28 and lasted a few days. The activity was registered by seismic monitors and increased conductivity was measured in the river Múlakvísl until May 7.

Last summer a large glacial burst, probably caused by a minor eruption in Katla, caused the river to swell and tear a hole in the Ring Road, right at the height of the tourism season in early July.

Oddur Sigurðsson, a geologist at the Icelandic Meteorological Office, told visir.is that the glacial burst in late April was so insignificant that it couldn’t be detected by the naked eye.
Oddur explained that it was caused by geothermal activity in one of Katla’s craters.
Volcano enthusiast and blogger Jón Frímann Jónsson reported on two events in Katla, on April 28 and May 6 or 7, and considers them to be warning signals: something is happening in the volcano, he predicts.
He also commented on the recent series of earthquakes which hit Herðubreið in the northeastern highlands early this week.

Earthquakes Hit Northeast Iceland

Series of Earthquakes Hit Northeast Iceland

A series of earthquakes began near Mt. Herðubreið in the northeastern highlands at noon yesterday and was still ongoing this morning. The largest quake measured 3.2 points on the Richter scale but most aftershocks, approximately 100, were below two points.

The most seismic activity was noted between 8 and 11 pm last night. A few quakes hit this morning but now the series seems to be subsiding, ruv.is reports.
It is common for series of minor earthquakes to hit the region near Herðubreið and there are no indications of upcoming volcanic eruptions or other activity in the area.
There were some concerns of volcanic activity by the nearby volcano Askja earlier this winter but scientific research concluded that there were no indications of an imminent eruption.
