An earthquake is when the Earth shakes, caused by tectonic activity in an area after the release of stored energy from the rock. Earthquakes most commonly occur on tectonic plate boundaries, and also occur along faults where previous movement has occurred. There are currently 500,000 detectable earthquakes in the world each year.
Earthquakes are a significant natural hazard to populations living in areas prone to them, and emergency responses to the hazard vary with economic development. The most powerful and destructive earthquakes occur at tectonic plate boundaries like the San Andreas Fault.
The severity of earthquakes is measured using the Moment Magnitude scale, which replaced the Richter scale with the largest quake ever recorded being 9.5 which struck Chile in 1960[1]. The Mercalli scale has also been used to measure earthquakes.
Liberals conceal the fact that severe earthquakes double every 40 years, as it is another Counterexample to an Old Earth
