Not one but two volcanoes on the same island in Alaska’s Aleutian chain were showing signs of unrest on Friday, rocked by seismic activity

Not one but two volcanoes on the same island in Alaska are showing signs of unrest. A swarm of earthquakes occurring since late February 2023 has intensified, a possible indication of an impending 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., the middle of three volcanoes on Tanaga Island, located about 1,250 miles southwest of Anchorage, the state's major population area.a volcano about 5 miles to the east of Tanaga.
However, an ash cloud could pose threats to aircraft, potentially disrupting air travel between North America and Asia, and health problems for communities farther away. Volcanic ash is angular and sharp and has been used as an industrial abrasive. The powdered rock can cause a jet engine to shut down., 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.
Some of the areas active in 2005 are where scientists are seeing a lot of earthquake activity now. “Where and how this activity will come to an end, whether or not it will lead to an eruption is an open question," Power said.Having two volcanoes this close and both in a state of unrest is very unusual in Alaska, Power said, even though there are such occurrences elsewhere in the world.
