Plate tectonics causes most volcanoes and earthquakes. When plates converge, diverge, or slip along another plate, volcanoes and earthquakes occur. There are other forms of volcanoes such as the Hawaiian Islands where volcanoes are formed over a hot spot in the mantel, and we have small earthquakes here in Wisconsin called rebound earthquakes where the land is actually still rising from the last ice age when it was depressed by the weight of the glaciers. There are other geophysical events that can create earthquakes too such as fracking.
