point to the northernmost. It is the second most active volcanic
system in the country with 26 known eruptions during the last 1100 years. Most
eruptions are explosive basaltic eruptions but large effusive eruptions are
known, such as the Þjórsárhraun that was formed ~8600 years ago and flowed 130
km following river channels.Holuhraun, October 2014. Photo: Morten S. Riishuus.For more

Seismic activity in Bardarbunga continues to be strong. The strongest earthquake since noon on Wednesday, 10.
December, was magnitude M4,6 yesterday at 12:40 on the northern rim of the caldera. About 15 earthquakes larger
then M4,0 were detected since Wednesday and about 20 earthquakes between M3,0-4,0. In total about 130
earthquakes were detected

activity in Bardarbunga continues to be strong. Five earthquakes between M4.0-4.6 were detected since the
last meeting of the Advisory Board on Friday. The strongest one was measured M4.6 yesterday at 21:35. About 10
earthquakes between magnitudes M3.0-3.9 were detected over the period. In total around 130 earthquakes were
detected around the caldera since last Friday, or between 20 and 30 per day

Very few smaller earthquakes were detected in the dyke and at the eruption site in Holuhraun.
An earthquake swarm was detected in Tungnafellsjokll glacier yesterday. The biggest earthquake was at 10:07 of
magnitude M2,8.

Yesterday, a group walked towards the eruptive site. Surveillance revealed much ash west and south of Grímsvötn. A few measurements, at locations where the ice was completely covered, gave ash thicknesses varying from 10 to 130 cm. Photo by Vilhjálmur Kjartansson, 25. maí 2011:
