We have been hearing some news that Karangetang, one of the more active volcanoes in the Indonesian arc, might erupt again soon – and sure enough, today it did. The details of the eruption are scant (beyond its likely coincidental timing just after the Japanese earthquake), but it seems that it was significant enough to prompt Indonesia officials to evacuate people living near the volcano.
