No significant changes have been observed regarding the seismic activity in and around Bárðarbunga volcano under Vatnajökull glacier and in the dike intrusion connecting it with the eruption in Holuhraun since the Icelandic Met Office’s last report, yesterday morning.
The strongest earthquakes in the Bárðarbunga caldera were recorded last night, magnitude 4.9 at 8:46 pm on the northwestern rim and magnitude 4.8 at 11:08 pm on the northern rim. Eight additional events were larger than magnitude 4.0 and 21 in the range magnitude 3.0-3.9. In total around 70 events were detected around the caldera, the Met Office’s latest update states.
Activity in the dike intrusion is low. None of the approximately 15 detected earthquakes in the dike exceeded magnitude 1.5. Most of them were located in the northern part of the dike and a few further to the south under Dyngjujökull outlet glacier. Minor activity has been detected around Herðubreið mountain and east of Askja volcano in the vicinity.
The eruption in Holuhraun in the northeastern highlands continues at stable levels. Camera observations are limited due to weather, but were occasionally possible yesterday in the late afternoon. No changes were seen on the camera or reported by scientists in the field.
