How does elastic rebound cause earthquakes

Which of the following is an aspect of the elastic rebound theory? Energy built up when plates try to get past each other is released when plates break free. An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. Stick-slip displacement on a fault radiates energy in the form of seismic waves, creating an earthquake.

The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus. Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Most tsunami damage and destruction is caused by flooding, wave impacts, erosion, strong currents, and floating debris e. The water can be just as dangerous, if not more so, as it returns to the sea, taking debris and people with it. The largest is the mainshock.

Aftershocks,… they are just earthquakes. Below this, where rocks are hotter, the material properties and behaviour of continental crust are still uncertain.

This is something that we are investigating. This site uses cookies: Find out more. Okay, thank you. This theory is known as the "elastic rebound theory. The following animation shows a bird's eye view of a country road that cuts through an orchard. Passing right down the middle of the orchard, and across the road, is a fault zone. The animation shows how the earth is gradually distorted about the fault, in response to distant forces, eventually leading to sudden slip or displacement along the fault--what we call an earthquake.
