Intraplate earthquake

Common card · No. 430828

An intraplate earthquake is an earthquake which occurs in the interior of a tectonic plate. They are relatively rare compared to the more familiar interplate earthquakes, which occur on the boundaries of tectonic plates. An earthquake that occurs within a subducting plate is known as an intraslab earthquake. Because buildings far from plate boundaries are rarely protected with seismic retrofitting, large intraplate earthquakes can inflict heavy damage. Examples of damaging intraplate earthquakes are the devastating 2001 Gujarat earthquake, the 2011 Christchurch earthquake, the 2012 Indian Ocean earthquakes, the 2017 Puebla earthquake, the 1811–1812 New Madrid earthquakes, and the 1886 Charleston earthquake.
