Do they expect it to happen again?


Answer by  patti (29325)

Mt. St. Helens erupted May 18th, 1980. The volcano is closely monitored. It is an active volcano and will eventually erupt again.

Mount Saint Helens erupted most famously on May 18, in 1980. It then stayed active until roughly 1991, then remained dormant until 2004. It stayed active until 2008, and is likely to become active again a number of times in the near future before returning to dormancy.
