Definition

The plate tectonics revolution of the mid-twentieth century provided Earth scientists with the fundamental framework to understand why most earthquakes occur within geographically limited active belts around the world along the plate boundaries. However, large devastating continental earthquakes do also occur in the plate interior far away from plate boundaries, which are known as intraplate earthquakes.

Mechanism of Intraplate Earthquakes

Moderate to large size devastating continental intraplate earthquakes have occurred at many locations in the world, e.g., 1811–1812 New Madrid (USA); 2008 Wenchuan (China); 2016 Christchurch (New Zealand); 1988 Tennant Creek (Australia); 1989 Ungava (Canada) and 2001 Kachchh, Koyna; and 1993 Latur, India. The occurrences of these earthquakes account for only 0.5% of the average annual global energy release by earthquakes (Johnston and Kanter 1990). The locations and mechanisms of M≥6 intraplate...
