Earthquake Information

An earthquake also known as a quake or a tremor is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are measured with a seismometer. The highest magnitude of an earthquake is 10.00. Earthquakes being mostly unpredictable and they can get up to magnitude 10.00 causing serious damage over large areas.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquake is located offshore it sometimes leads to cause a tsunami. The shaking in earthquakes can also cause landslides and occasionally volcanic activity.

Over time, stresses build beneath the earth's surface. Occasionally, stress is released resulting in the sudden, and sometimes disastrous shaking we call an earthquake. The shaking could last seconds or minutes, and there may be several earthquakes over a period ranging from hours to weeks called fore shocks and aftershocks,the latter decreasing in mag magnitude with time.

Most earthquake casualties result not from ground movement but from failing objects and debris
