Alaska Volcano Spreads Ash 106 Miles Away

Alaska's Mount Redoubt erupted continuously during the end of March and into April, spewing ash nearly 65,000 feet in the air, according to the U.S. Geological Survey (USGS). Trace amounts of ash were found up to 106 miles away in Anchorage.

 

The ash, which consisted of tiny rock fragments with jagged edges, threatened national and international aviation as it entered the North Pacific flight path between North America and Asia.

The USGS said Redoubt is one of the nation's most threatening volcanoes, and is monitored 24 hours a day by scientists at the Alaska Volcano Observatory.
