This year marks the 30th anniversary of the moment, at 8:32 a.m. on May 18, when a magnitude-5 eruption triggered the biggest landslide in recorded history. The bulging north face of the mountain gave way, uncorking a gas-charged reservoir of magma in an event that leveled 150 square miles of forest, killed 57 people and jetted a 15-mile-high plume of ash that circled the globe.
