Alaska’s Volcano Erruptions Could Last For Months

April 3, 2009

Alaska’s Redoubt Volcano eruptions, which to date have included 18 explosions and the non-stop emission of gases and ash, could last for several months, according to the U.S. Geological Survey. Scientists at the Alaska Volcano Observatory monitor the volcano 24 hours a day (using seismometers, satellites, radar, cameras, and pressure sensors) to identify activity that cause hazardous conditions for air travel and produce mudflows and distant ash falls affecting air quality.

Anchorage, the most populous city in Alaska, has already been dusted with ash on one occasion, closing the airport for 20 hours, USGS said.
