WebVolcanoes form where the subducting oceanic plate gets hot enough to “sweat” fluids and initiate melting. (Modified from Lillie, 2005.) Subduction zones produce volcanic arcs, curving chains of steep-sided volcanoes, for example the Aleutian Islands in Alaska.
WebAreas where volcanoes that form on land away from tectonic plate boundaries are known as hotspots. These volcanoes are formed when hot magma rises through intrusions in the crust known as mantle plumes. Hotspots form above stationary regions of extremely hot magma under the earth’s crust.

WebSep 27, 2024 · As the volcano moves farther from the hot spot, it goes extinct and e ventually erodes back into the ocean. A new and active volcano develops over the hot spot, creating a continuous cycle of volcanism—and a string of volcanic islands tracing the tectonic plate ’s movement over time. WebVolcanic hot spots are plumes of molten rock which rise from the mantle and cause the crust to melt, creating magma resulting in volcanic activity.
