What is the origin of an earthquake called?
The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.
What are the two origin of an earthquake?
There are two types of earthquakes: tectonic and volcanic earthquakes. Tectonic earthquakes are produced by sudden movement along faults and plate boundaries. Earthquakes induced by rising lava or magma beneath active volcanoes is called volcanic earthquakes.
What are the 3 main causes of earthquakes?
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.
What are the 4 types of earthquakes?
There are four different types of earthquakes: tectonic, volcanic, collapse and explosion. A tectonic earthquake is one that occurs when the earth's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.
What’s the main cause of most earthquakes?
Earthquakes are caused by a sudden release of stress along faults in the earth's crust. The continuous motion of tectonic plates causes a steady build-up of pressure in the rock strata on both sides of a fault until the stress is sufficiently great that it is released in a sudden, jerky movement.

Three Kinds of Earthquakes
- Shallow fault earthquakes. A fault is a break in the rock beneath our feet. …
- Subduction zone earthquakes. The largest earthquakes ever recorded are subduction zone earthquakes. …
- Deep earthquakes. Deep earthquakes occur in the subducting ocean slab, deep beneath the continental crust.
What are the 4 main causes of earthquakes?
Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. The energy can be released by elastic strain, gravity, chemical reactions, or even the motion of massive bodies.

What faults cause earthquakes?
Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on reverse or thrust faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
