Why is Mt St Helens active?

Scientists from the U.S. Geological Survey Oregon State University and the University of Canterbury in New Zealand found that the mountain is sitting right on top of the spot where two tectonic plates were welded together millions of years ago. That created a weak point where magma can rise up through the crust.

Why did Mt St Helens erupt?

The landslide exposed the dacite magma in St. Helens’ neck to much lower pressure causing the gas-charged partially molten rock and high-pressure steam above it to explode a few seconds after the landslide started. Explosions burst through the trailing part of the landslide blasting rock debris northward.
