Difference between 1980 eruption of Mount St. Helens and Volcanic landslide

1980 eruption of Mount St. Helens vs. Volcanic landslide

On March27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A volcanic landslide or volcanogenic landslide is a type of mass wasting that takes place at volcanoes.

Pyroclastic flow

A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of but is capable of reaching speeds up to.

Volcano

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
