May 18, 1980: Mount St. Helens volcano erupts

At 8:32 a.m. on May 18th, 1980, a 5.2 magnitude earthquake struck below the north face of Washington's Mount St. Helens.
Vulcanologist David Johnston was camping only a few miles north of the volcano, and radioed the USGS base in Vancouver, Washington: "Vancouver, Vancouver, this is it!"
