North American Plate
Mount Shasta is inside the western end of the North American continental plate, west of it under the Pacific ocean the Pacific oceanic plate is subducting under the North American continental plate. Deep under the North American continental plate friction with the descending Pacific oceanic plate, melts rock in the contact zone which feeds the magma supply of Mount Shasta. As the magma surfaces trapped ocean water flashes to steam producing explosive lava.
Mount Shasta is on the North American Plate.
Mount Etna is an active volcano in Sicily, Italy that constantly erupts. Mount Etna is a continental plate as it is created by the earth's crust's movements
HOW MOUNT SHASTA WAS FORMED...It was built from repeated eruptions throughout the years,Mt. Shasta is in Sacramento and it a composite volcano.
The Juan de Fuca plate, which is subducting under the North American plate. Mount Shasta is at the southern end of the same Cascade volcanic range that includes Mount St. Helens and extends northward into British Columbia, Canada.
Mount Vesuvius is located on a continental plate, specifically the Eurasian Plate. It is within the boundaries of the subduction zone where the African Plate is being subducted beneath the Eurasian Plate, leading to volcanic activity in the region.
Mount Merapi is not a plate. However, it was formed by the convergence of a oceanic plate and a continental plate. The oceanic Indo-Australian plate subducted under the continetal Eurasian plate causing a line of volcanoes.
Mount Shasta formed as a result of subduction, where the Juan de Fuca tectonic plate dives beneath the North American plate, causing magma to rise and create the volcano. It is a prominent feature in the Cascade Range due to its explosive past eruptions and steep slopes.
Mount Fuji is located on the boundary of the Pacific Plate and the Eurasian Plate. Specifically, it is situated near the junction where the Philippine Sea Plate also interacts with these plates. This tectonic setting contributes to the volcanic activity associated with Mount Fuji.
Mount Meakan is located on the Eurasian Plate.
Lassen Peak and Mount Shasta are both located in the Cascade Range in California and are associated with the subduction of the Gorda Plate beneath the North American Plate. The intense heat and pressure from the subduction process cause melting in the mantle, leading to the formation of magma chambers beneath these volcanoes. The volcanic activity at Lassen Peak and Mount Shasta is a result of this magma rising to the surface and erupting.
these volcanoes are the southernmost volcanoes of the cascade volcanic chain.
