Aftermath of Mount St. Helens
Many agricultural crops, such as wheat, apples, potatoes, and alfalfa, were destroyed.
The ash fall created temporary but major problems with transportation, sewage disposal, and water treatment systems.

Mount St. Helens After May 18, 1980
St. Helens produced five more explosive eruptions between May and October 1980.
Through the early 1990, a total of at least 21 periods of eruptive activity had occurred.
The volcano remains active, with smaller, dome- building eruptions continuing into 2008.
After the 1980 eruption, Congress funded the USGS Cascades Volcano Observatory to monitor volcanoes in the Cascade range. The budget for monitoring volcanoes went from $2 million in 1980 to $21 million today, and the USGS now has close to 120 volcanologists on staff.
