Volcanic eruptions, even deadly ones can sometimes be directly triggered by a large nearby earthquake. This most famously occurred at Mount Ararat in 1840, Mount Fuji in 1707, and Kilauea in 1975. Today's video explains the scientific reasoning on why, under a very specific set of circumstances one disaster can potentially cause another. Numerous examples are given, although I want to stress that an earthquake triggering a volcanic eruption is still quite rare.
