Bardarbunga (Iceland): Eruptive activity at the Holuhraun fissure remains stable. The lava flows continue to expand towards the north and particularly to the east, now over a snow-covered landscape as winter conditions set in.
Earthquakes under the intrusive dyke decrease slowly, but remain frequent and strong under the caldera of the central volcano, which subsides at a more or less constant rate of 50 cm per day.
Ontake-san (Honshu): (28 Sep) Yesterday’s eruption might have caused more than 30 fatalities, Japanese press reports. Most of them were apparently killed by heart and respiratory failure after inhaling ash when caught in the outer areas of a pyroclastic flow or ash cloud descending the mountain.
At least 40 people were severely injured and 250 climbers were initially left stranded on the mountain.
AP reported that 7 people were rescued by helicopter. Rescue operations are in full swing on Japan’s second highest mountain.
JMA raised the alert level to 3 and declared a 4 km exclusion zone around the volcano.
