This is a common movie eruption style, a mix of explosive (big ash plumes, pyroclastic flows) and effusive (runny lava flows). It makes for good movie scenes. Webmajor reference. In volcano: Subduction volcanoes. As an oceanic plate is subducted beneath a continental plate, seafloor sediments rich in water and carbon dioxide are carried beneath the overriding plate. These compounds may act as fluxes, reducing the melting temperature of magma. Although the process is not clearly understood,…. Read More.

WebIn geology, a hotspot is an area of the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust. Samoa is composed of a linear chain of volcanic islands situated atop the Pacific tectonic … WebA hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms.
