Roundup of Global Volcanic Activity

Bardarbunga (Iceland): The eruption continues with most activity (lava fountains and lava flow emission) now occurring from the central vent on the Holuhraun fissure. Seismic activity remains elevated, mostly under the northern rim of the caldera of the central Bárdarbunga volcano, but also under Herðubreið and the northern part of the intrusion. A slight increase in earthquake activity under the caldera can be seen over the past days. The 4 strongest events today so far were between magnitude 3.4 and 4.8, all under the Bárdarbunga caldera, which continues to subside.

Semeru volcano (East Java, Indonesia) activity update: Our recent tour group on Java observed mild ongoing strombolian activity in the volcano's summit crater. A flat lava dome is growing there and extruding a viscous lava flow into the open ravine to the south flank.
