There are a number of causes. In some cases the magma beneath a volcano cools until it is too viscous to erupt, and can even solidify completely if given enough time. A new injection of magma from the mantle can cause activity to resume. Sometimes the ultimate source of magma is removed as the plate moves away from a hot spot, or is consumer by subduction.
