Roundup of Global Volcanic Activity

Bardarbunga (Iceland): A new eruptive phase has started at the same fissure that had been briefly active Friday morning. The new eruption seems to be bigger than the previous one and located slightly north of the Friday fissure vent. The active fissure was estimated to be 1.5 km long and is located approx. 9 km north of the Dyngjujökull glacier in the Holuhraun lava plain. At the same time, intense seismic activity continues. More than 200 earthquakes have been detected since midnight, both under the active intrusion under and north of the rim of the glacier NE of the volcano as well as under the caldera of Bárdarbunga itself. The stringest were 7 quakes with magnitudes between 3.0 and 3.8. According to IMO, "the new eruption started in Holuhraun shortly after 04 AM, on the same volcanic fissure, which erupted earlier this week. The fissure is estimated to be 1,5 km long. "...Fewer earthquakes seem to follow the event than in the previous eruption, but more lava is being extruded. At 07 AM the lava flow was around 1 km wide and 3 km long towards northeast. The thickness was estimated a few meters, the flow about 1000 m3 pr second. Approximately 500 earthquakes were detected in the area and smaller than before. The strongest earthquake, M3.8 was in the Bárðarbunga caldera. Poor weather conditions prevail in the area, which makes detection of smaller earthquakes difficult.
