Seismic activity in Alaska’s Aleutian Islands heralds a higher chance of volcanic eruptions -
At 5:22 p.m. local time Thursday, the observatory sent out an alert, noting that earthquake activity had increased in the vicinity of the Takawangha volcano over the previous 48 hours. This, scientists said, could presage a volcanic eruption.
As of Thursday night, several small earthquakes were rumbling under Tanaga per minute. The largest seismic event within 24 hours of the AVO alert was a magnitude 3.9 earthquake under Tanaga. If either volcano erupts, the closest community affected would be Adak, 65 miles from the volcanoes. The town of around 170 would experience ashfall.
