Glacier Peak has produced large explosive eruptions that have dispersed major tephra deposits over broad distances and has been frequently active during the past 5,500 years. Its eruptions were accompanied by lava dome growth, pyroclastic flows, and lahars that traveled to lowland areas far from the volcano.
