When a kind of energy held inside the Earth's crust is abruptly released, typically when masses of rock rubbing up against one another unexpectedly crack and "slide," seismic waves are created. Geologic faults, which are confined areas where rock masses can move in relation to one another, are where earthquakes happen most frequently. The largest tectonic plates that make up the crust of the Earth are where the majority of  the world's major fault lines are found.
