WebFeb 11, 2024 · There are three types of tectonic plate boundaries: Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; At a convergent plate boundary, one plate dives (“subducts”) beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate; Transform plate ...

WebVolcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones, although only the Aleutian Trench and the Java Trench appear on the map in Figure above.

(Modified from Lillie, 2005.)
