On May 18, 1980 in Washington State, an ash-cloud covered a hilltop. A landslip caused by an earthquake on Mount St. Helens North Slope removed the summit of the mountain and set off a volcanic eruption that killed 57 people, destroyed river basins, and uprooted enough plants to build 300,000 homes.

This Thursday, 18 May 2023, the Mount St. Helens explosion from 1980 will be remembered for the 43rd consecutive time. The 1980 Mount St. Helens explosion was the most deadly eruption in American history. It killed 57 people and released 520 million tonnes of ash across the country.
