The point inside the crust where the pressure is released is called the focus or Seismic focus.
The point on the Earth's surface above the focus is called the epicenter.
Earthquake energy is released in seismic waves.
Plutonism is the process by which magma rises through the crust and crystallizes as an intrusive igneous rock beneath the Earth's surface.
A tectonic plate (also called a lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
