A look back 35 years after Mount St. Helens’ deadly eruption

Associated Press  

SEATTLE — Thirty-five years ago, Mount St. Helens in southwest Washington state erupted, killing 57 people, blasting more than 1,300 feet off the top and raining volcanic ash for miles around. ____ THE DAY IT BLEW Within minutes of a 5.1 earthquake that hit at 8:32 a.m. on May 18, 1980, the volcano’s north flank collapsed, triggering the largest landslide in recorded history. A lava dome began to rise in the volcano’s crater, building slowly over three years during the eruption period that lasted from 2004 to 2008. ___ THE NEXT BIG ONE Scientists say Mount St. Helens is the most active volcano in the Cascades and the most likely to erupt again, perhaps in this generation, but they can’t predict years in advance when or how big it will be.
