Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history.

By the first half of the 20th century, earthquake detection and monitoring had advanced to the point that the magnitude of a given earthquake could be measured quantitatively, first using the Richter scale (ML) and later using the moment magnitude (Mw) scale.

6 days ago · Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.

The most widely felt earthquakes in the recorded history of North America were a series that occurred in 1811-1812 near New Madrid, Missouri. A great earthquake, whose magnitude is estimated to be about 8, occurred on the morning of December 16, 1811.

A major deep-focus earthquake occurs under Japan on January 21. A Great earthquake occurs in Columbia and Ecuador on January 31. The Great 1906 San Francisco earthquake occurs on April 18, with a great extent of strike-slip faulting. A re-triangulation survey leads to elastic-rebound theory of earthquakes (see 1910).
