The term intraplate earthquake refers to a variety of earthquake that occurs within the interior of a tectonic plate; this stands in contrast to an interplate earthquake, which occurs at the boundary of a tectonic plate. Intraplate earthquakes are often called "intraslab earthquakes", especially when occurring in … See more The surface of the Earth is made up of seven primary and eight secondary tectonic plates, plus dozens of tertiary microplates. The large plates move very slowly, owing to convection currents within the See more Examples of intraplate earthquakes include those in Mineral, Virginia in 2011 (estimated magnitude 5.8), Newcastle, New South Wales in 1989, New Madrid in 1811 and 1812 (estimated … See more • New Madrid Seismic Zone – Major seismic zone in the southern and midwestern United States • Wabash Valley Seismic Zone – major sesmic zone in Lower Ohio Valley, … See more • Stein, S., and S. Mazzotti (2007). "Continental Intraplate Earthquakes: Science and Policy Issues", Geological Society of America, Special Paper 425. See more Many cities live with the seismic risk of a rare, large intraplate earthquake. The cause of these earthquakes is often uncertain. In many cases, the causative fault is deeply … See more Scientists continue to search for the causes of these earthquakes, and especially for some indication of how often they recur. The best success has come with detailed micro-seismic monitoring, involving dense arrays of seismometers. In this manner, very … See more • Intraplate Earthquakes: Possible Mechanisms for the New Madrid and Charleston Earthquakes • Symptomatic Features of Intraplate Earthquakes – PDF See more
