Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other. Earthquakes are most common along fault lines ...
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
This zone of intense earthquake activity is located deep within the interior of the North American plate. An intraplate earthquake occurs in the interior of a tectonic plate, in contrast to an interplate earthquake on the boundary of a tectonic plate. [1] [2] They are relatively rare compared to the more familiar interplate earthquakes.
The topmost, brittle part of the Earth's crust, and the cool slabs of the tectonic plates that are descending into the hot mantle, are the only parts of our planet that can store elastic energy and release it in fault ruptures. Rocks hotter than about 300 °C (572 °F) flow in response to stress; they do not rupture in earthquakes.

Movement of tectonic plates against each other sends seismic waves rippling across earth’s surface
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (M w) that can exceed 9.0.
While earthquakes are most common along the fault lines of tectonic plates—of which there are seven major ones in the world—the seismic quakes can actually hit anywhere, at any time, according ...
