Mount St. Helens landslide (1980)

The Mount St. Helens landslide in 1980 was a massive natural event triggered by a volcanic eruption. Underground magma movements caused the volcano's northern side to weaken and collapse in a gigantic landslide, removing the upper part of the mountain. This sudden movement of earth and rock released pressure beneath the surface, leading to a violent eruption that ejected ash and gases high into the atmosphere. The landslide was one of the largest in recorded history, drastically reshaping the landscape, destroying forests, and impacting local ecosystems. It provided valuable insights into volcanic behavior and landslide dynamics.
