About the Mount St. Helens 1980 Eruption & Aftermath
On the morning of May 18, 1980, a magnitude 5.1 earthquake triggered the collapse of the summit and north flank of Mount St. Helens and formed the largest landslide in recorded history. In 1982 Congress designated the 110,000-acre Mount St. Helens National Volcanic Monument. The following decades have offered insight into the biological recovery of ravaged landscapes.
