Intraplate earthquake - Wikipedia
An intraplate earthquake is an earthquake that occurs in the interior of a tectonic plate, in contrast to an interplate earthquake on the boundary of a tectonic plate. Learn about the causes, characteristics, examples and prediction of intraplate earthquakes, and how they differ from interplate earthquakes.
