The models capture the frequency and magnitude of "tail" scenarios—infrequent events that cause large losses—as well as low loss periods, both of which contribute to estimates of average annual loss. An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities.
