Roundup of Global Volcanic Activity
Bárdarbunga (Iceland): The intense seismic crisis caused by a significant laterally migrating magma intrusion continues to evolve with little changes.
Earthquake activity has been a bit weaker yesterday, only to pick up again today. Two more magnitude 5+ quakes occurred after midnight near the caldera of the Bardarbunga central volcano.
The intrusion is now 45 km long and roughly 20 km deep, but so far remains mostly below 5 km depth. Horizontal spreading between the Dyngjuháls (DYNC) and Kverkfjöll (Gengissig, GSIG) GPS stations approaches 50 cm.
