Roundup of Global Volcanic Activity

Bárdarbunga (Iceland):The seismic crisis in Bárðarbunga and Dyngjujökull continues strongly. Today alone, more than 400 quakes of magnitudes up to 4 were detected, mostly at the N end of the active intrusion that has been going on. The location of the quakes indicating the front of the magma intrusion (dyke) continues to advance northwards. Its tip is now outside the glacier and approaching the Askja caldera. In case of an eruption, it is now more likely that at least some of it occurs on land (and not under the glacier).

Popocatépetl volcano (Mexico): The volcano had a phase of stronger activity this morning, but overall this remains similar to the past months. A discrete explosion ejected an ash plume approx 1 km high and a phase of strong steaming, possibly with some ash emissions, occurred this morning.

Tungurahua volcano (Ecuador) activity update Intermittent explosive activity of moderate size continues at the volcano. An ash emission to flight level 280, i.e. 28,000 ft (8 km) altitude and drifting west was reported today.
