Earthquake

(redirected from Tectonic earthquake)
Also found in: Dictionary, Thesaurus, Encyclopedia.
A geological event caused by shifting tectonic plates, triggered by a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are recorded with a seismometer, also known as a seismograph. The moment magnitude (or the related and mostly obsolete Richter magnitude) of an earthquake is conventionally reported. Magnitudes of 3 or lower are mostly imperceptible; magnitudes of 7 or more cause serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale
Cause of death Direct trauma due to collapse of buildings, dehydration, shock, crush injury

Thus, it is misleading to compare tectonic earthquakes and induced seismicity without accounting explicitly for variance in loading mechanisms.
Such threats included acts of bioterrorism, nuclear calamities and/or nuclear warfare, overpopulation, asteroid and meteor threats, super volcanoes, mass tectonic earthquakes, rogue self-replicating nano-machines, superintelligent computers and high-energy chain-reactions that could disrupt the fabric of space itself.
