Roundup of Global Volcanic Activity
Bardarbunga (Iceland): The eruption continues with little changes. Fountaining is now limited to the central vent on the main fissure. The southernmost vent, still active on Friday, stopped erupting yesterday. Earthquake activity has been stable compared to recent days. Approx. 140 events were detected since midnight (until 18:50 local time). The quakes concentrate in the northernmost part of the dyke intrusion, from the eruption site to about 6 km into Dyngjujökull glacier. Earthquakes in the intrusion hardly exceed magnitude 2: as the magma has an open way to the surface now, no new fractures need to be broken, and earthquake activity has dropped as a result.
