The blowdown zone of Mount St. Helens, following its catastrophic eruption on May 18, 1980, extended approximately 230 square miles (600 square kilometers). The force of the eruption produced a lateral blast that knocked down millions of trees and flattened vegetation in the surrounding area. This devastation was primarily concentrated in the north and northeast directions, where the effects of the blast were most severe. The event significantly altered the landscape and ecosystem of the region.
