Quick Answer
The eruption devastated the north side of Mount St. Helens in Washington, USA. The summit collapsed and a huge lateral blast swept through the surrounding forest.
The Full Story
Mount St. Helens is in southwestern Washington state, in the Cascade Range. On 18 May 1980, a magnitude 5.1 earthquake triggered a massive landslide, followed by a sideways explosion that blew out the volcano’s north flank. The blast flattened forests across a wide area and sent ash across much of North America. The eruption remains one of the best-studied volcanic disasters in modern history.
