Related to seismic activity: Volcanic activity
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
