Up to several earthquakes per minute are occurring under Tanaga Island, where two volcanoes are located, officials said.
The island is about 1,250 miles southwest of Anchorage. There are no communities there, but Adak, a city of about 170 people on another island, is about 65 miles away and could see ashfall.
If one of the volcanoes were to erupt, it could be a problem for aircraft. The Aleutians are below the routes that jets fly between North America and Asia. Volcanic ash is angular and sharp and can cause airplane engines to shut down. Past eruptions had both ash clouds and viscous lava that moves slowly, much like what happened at Mount St. Helens in Washington state in 1980.
No historical eruptions are known from Takawangha but field work shows recent eruptions have occurred and it's possible historic eruptions attributed to Tanaga may instead have come from Takawangha, according to scientists.Former accountant Mario David García Mansilla gets up at 5 a.m. every day and heads to Pacaya, an active volcano near Guatemala City, Guatemala. There, Mansilla continues at the craft he has worked to hone for years: making the perfect pizza in a volcanic oven.
