An earthquake is an effect of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground

An earthquake is an effect of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.

The earthquake focus of an earthquake is the point where the rocks break. Directly above the focus on the Earth's surface is the earthquake epicenter. Check out Myrna Martin's award winning textbooks, e-books, videos and rock sets

The earthquake focus of an earthquake is the point where the rocks break. The epicenter is the point on the surface of the Earth above an earthquake. Earthquake waves start at the focus and travel outward in all directions. Earthquake waves DO NOT originate at the epicenter. News stories about earthquakes.

A deep-focus earthquake in seismology (also called a plutonic earthquake) is an earthquake with a hypocenter depth exceeding 300 km. They occur almost exclusively at convergent boundaries in association with subducted oceanic lithosphere. They occur along a dipping tabular zone beneath the subduction zone known as the Wadati–Benioff zone. Preliminary evidence for the existence of deep-focus earthquakes was first brought to the attention of the scientific community in 1922 by Herbert Hall Turner
