Mount St.Helens is still showing signs of activity

Washington's Mount St. Helens continues to erupt after rumbling to life three years ago following an 18-year lull.

"It's been an amazing run," said Seth Moran, a seismologist with the U.S. Geological Survey's Cascades Volcano Observatory.

Mount St. Helens' seismic activity has slowed since hundreds of small earthquakes signaled its return to life three years ago Sunday, but it shows no sign of stopping any time soon, Moran told the Portland Oregonian in a story published Monday.

Moran and other scientists are monitoring nearby Mount Rainier and other potentially dangerous Cascade volcanoes as they apply lessons learned from Mount St. Helens.

"We have to be prepared for what these volcanoes can do," Moran said. "You want to be ahead of the game by being able to detect even small changes."

On May 18, 1980, St. Helens erupted in a blast that killed 57 people and blew 1,314 feet off its top.
