Mount St. Helens was created due to the subduction of the Juan de Fuca plate below the North American plate. This subduction caused partial melting of material in the mantle which formed magma. This magma was more buoyant than the surrounding material so migrated towards Earth's surface, resulting in the formation of volcanoes in the Cascades mountain range, including Mt. St. Helens.
