Stages of an Earthquake

1. Elastic Buildup. The elastic rebound theory is based on the concept that the earthquakes result from forces nowhere near the actual earthquake. …
2. Dilatancy. Stage two occurs when the rocks in the Earth are packed together as closely as possible. …
3. Influx of Water. …

What are the events of an earthquake?

An earthquake is the ground shaking caused by a sudden slip on a fault. Stresses in the earth's outer layer push the sides of the fault together. Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the earth's crust and cause the shaking that we feel during an earthquake.

What are the 4 parts of an earthquake?

It's these waves that you feel during an earthquake.

• Fault: A fracture in the rocks that make up the Earth's crust.
• Epicenter: The point at the surface of the Earth above the focus.
• Plates: Massive rocks that make up the outer layer of the Earth's surface and whose movement along faults triggers earthquakes.

What are the 5 steps of an earthquake?

What is the sequence of events in an earthquake cycle?

By increasing the amplitude of the fluctuations in the spatial distribution of these stresses, the type of earthquake sequence can be varied progressively from an 'isolated earthquake', to a sequence with foreshocks, main shock and aftershocks, and finally, to an earthquake swarm.

Where does earthquake happen?

The Earth's crust (the outer layer of the planet) is made up of several pieces called tectonic plates and most earthquakes occur along their edges. The plates under the oceans are called oceanic plates. Plates that are not under the ocean are continental plates.

What are the 3 main parts of an earthquake?

There are three main parts to an earthquake: the focus, or origin of the event; the seismic waves; and the fault along which the earthquake occurs.

Which of the following events causes an earthquake?

An earthquake is a sudden shaking or trembling of the earth which lasts for a very short time. Most earthquakes are caused by the movement of earth's plates. Tremors on the earth can also be caused when a volcano erupts, or a meteor hits the earth, or an underground nuclear explosion occurs.

What are the 3 main causes of an earthquake?

Causes of Earthquakes in General

• Induced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
• Volcanic Earthquakes. Volcanic quakes are associated with active volcanism. …
• Collapse Earthquakes.

Why do earthquake happens?

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.
