Roundup of Global Volcanic Activity

Bardarbunga (Iceland): No significant changes have occurred at the ongoing fissure eruption in Holuhraun. The lava effusion rate seems to remain stable, according to IMO. Subsidence, or slow caldera collapse, of the Bárdarbunga caldera continues at rates of approx. 50 cm per day. Seismic activity remains elevated. The largest earthquake yesterday and today was a magnitude 5.3 event at 14:21 local time and a magnitude 4.7 this morning. Irregular horizontal displacements of the crust revealed by GPS stations probably indicate that magma movements underground are changing, but it is impossible to predict what the consequences will be.
