What is a convergent earthquake?

A convergent earthquake happens when two techtonic plates are moving toward each other and one is submerging under the other. Think of a car accident between a Mazda and a Humvee. The Mazda would be the submerging plate in this example....and because they're coming toward each other (the plates), it is more destructive. When tectonic plates slide along each other, its a transform border....more like a side swipe instead of a head on collision.
