What was the evacuation plan for mt st helens?

Answer 1

The evacuation plan for Mount St. Helens, particularly during the 1980 eruption, involved a series of warnings and zones established by the U.S. Forest Service and other agencies. Residents living within a designated evacuation zone, especially within a five-mile radius of the volcano, were encouraged to leave as the threat increased. Authorities implemented roadblocks and provided information to facilitate safe evacuations, while public education campaigns informed locals about the signs of volcanic activity. Ultimately, the plan helped minimize casualties when the volcano erupted on May 18, 1980.
