Approximately 70 earthquakes occurred on the Bárðarbunga caldera rim in the last 24 hours reports the Iceland Met Office this morning. The strongest quakes were of the magnitude of 4.8 yesterday at 13:21 and at 4.6 at 01:36. Seven earthquakes altogether exceeded the magnitude of 4, and 15 earthquakes were in the magnitude range of 3-3.9. Subsidence of the caldera is continuous.
According to the Iceland Met Office, no significant changes are observed in the seismic activity around the Bárðarbunga volcanic system.
Around 30 events have been detected in the northern part of the dyke intrusion, between northern Dyngjujökull and the eruption site in Holuhraun. The strongest ones were both of the magnitude 1.4 yesterday at 10:07 and 13:33.
An earthquake of 3.0 occurred southeast of mount Herðubreið yesterday afternoon at 17:04 and around 10 smaller quakes followed. The region around mount Herðubreið and Herðubreiðartögl has been moderately active in recent days. Although this activity might be a response to increased stress due to the dyke intrusion south-southwest, the region has been frequently active in the past and a direkt link between the intrusion and the present activity is not obvious. No activity was observed under Tungnafellsjökull.
