Mount St. Helens, in Washington State (Northwest U.S.), erupted on May 18, 1980. It was extremely intense, spewing out around 2.9 cubic kilometres of material.

The eruption itself was preceded by two months of earthquakes and steam jets caused by the infiltration of magma at shallow depth below the mountain.

This magma provoked a network of fractures and deformations in the north side of the volcano; on May 18, 1980 at 8:32 am, an earthquake triggered a massive landslide on the north face. In less than twenty seconds, the magma erupted in the form of a pyroclastic flow.
