Alaska's Mount Redoubt Erupts Six Times

Alaska's Mount Redoubt volcano erupted six times, sending an ash plume more than 9 miles into the air in the volcano's first emissions in nearly 20 years. Ash from Alaska's volcanos is like a rock fragment with jagged edges and has been used as an industrial abrasive. It can injure skin, eyes and breathing passages. The young, the elderly and people with respiratory problems are especially susceptible to ash-related health problems. Ash can also cause damage engines in planes, cars and other vehicles. Alaska Airlines on Monday canceled 19 flights because of the ash. In-state carrier Era Aviation canceled four, and Elmendorf Air Force Base in Anchorage kept 60 planes, including fighter jets, cargo aircraft and a 747 commercial plane, in shelters...Fox News
