Blast oleh Jeffrey H. Ryan

On May 18, 1980, Mount St. Helens erupted with fury. Triggered by the largest landslide ever recorded, a devastating lateral blast blew off the entire northern side of the volcano. Searing hot gasses, traveling at 650 miles per hour, scorched trees nearly twenty miles away. The mountain instantly lost 1300 in elevation. A slurry of mud, ash and melting ice inundated the landscape, which was then buried in 540 million tons of ash, and fifty-seven people lost their lives.
