New Factsheet | February 24, 2015

New factsheet here.

For the last few days there has been very poor visibility of the eruption in Holuhraun due to bad weather.

  • Seismic activity in Bárðarbunga continues to diminish although it can still be considered strong. The strongest earthquake since Friday was measured M3.7 on Saturday, 21st of February, at 15:20. Two other earthquakes stronger then magnitudes M3.0 were detected over the period. In total around 60 earthquakes were detected around the caldera since last Friday. Two deep earthquakes were detected 18 km southeast of Bárðarbunga. The former on 20th of February at 02:50 on 19 km depth, and the later on 21st of February at 21:55 on 16 km depth. No earthquake over M5.0 has been detected in Bárðarbunga since 8. January.

  • Around 90 earthquakes were detected in the dyke during the same period. The strongest ones were measured M1.6. It is worth to mention that bad weather does affect the number of small earthquakes detected.

  • The rate of the subsidence in Bárðarbunga caldera is now less than 2 cm a day. Ice is subsiding into the caldera does effecting that the data coming from the GPS station in the caldera.

  • GPS measurements near Vatnajökull glacier show continuing slow deflation towards Bárðarbunga, indicating a flow of magma from under the volcano.

  • Two earthquakes were detected around Tungnafellsjökul glacier, both smaller then M2.0. About 40 earthquakes were detected around Askja and Herðubreið since last Friday. All of them smaller than M2.0.
