Mount St. Helens Erupts in Washington State
On the morning of May 18, 1980, Mount St. Helens in Washington State erupted in the most destructive volcanic event in modern U.S. history. A massive earthquake triggered a lateral collapse of the volcano's north face, unleashing a pyroclastic surge that flattened 230 square miles of forest in minutes. The eruption killed 57 people, including volcanologist David Johnston and innkeeper Harry R. Truman who had refused to evacuate. Ash fell across eleven states, and the eruption column rose 15 miles into the sky. The blast reduced the mountain's height by more than 1,300 feet and left a crater a mile wide. It fundamentally changed scientists' understanding of volcanic hazards and became one of the most closely studied geological events in history.
