Two volcanos on the same island in Alaska's Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption.
ANCHORAGE -- Not one but two volcanos on the same island in Alaska's Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption.
"We're still getting earthquakes up above magnitude 3 going on quite regularly," said John Power, a research geophysicist with the U.S. Geological Survey stationed at the Alaska Volcano Observatory in Anchorage. "We've seen actually earthquake activity building beneath both epicenters and in between them, which is causing us quite a bit of concern about what's going on," Power said."It's a very energetic sequence."
An interagency volcanic ash response plan, developed in 2011, details how state, federal and local agencies should respond to a volcanic eruption in the region that can cast ash throughout the area. It calls for the Alaska Volcano Observatory to take the lead in confirming an eruption and notify other agencies, which would then alert pilots, mariners and local communities.
