At 8:32 Sunday morning, May 18, 1980, Mount
St. Helens erupted.
Shaken by an earthquake measuring 5.1 on the Richter scale, the north
face of this tall symmetrical mountain collapsed in a massive rock debris
avalanche. Nearly 230 square miles of forest was blown over or left dead and
standing. At the same time a mushroom-shaped column of ash rose thousands of
feet skyward and drifted downwind, turning day into night as dark, gray ash
fell over eastern Washington and beyond. The eruption lasted 9 hours, but
Mount St. Helens and the surrounding landscape were dramatically changed
within moments.
In 1982 the President and Congress created the 110,000-acre National
Volcanic Monument for research, recreation, and education. Inside the
Monument, the environment is left to respond naturally to the disturbance.
