Where is the epicenter of an earthquake located?

Answer 1

Earthquakes most commonly occur at or near the boundaries of tectonic plates. Earthquakes can also occur away from plate boundaries on fault lines however these tend to be of smaller magnitude.

Earthquake occur along plate boundaries. The earth is split into major tectonic plates. Examples include the Pacific plate and the Indo-Australian plate.

Tectonic plates are always moving. An a point where 2 plates meet, they converge (move into each other) or diverge (move away from each other). These locations are known as fault lines. In both scenarios, an earthquake may occur.

Earthquakes are associated with the sudden release of energy built up within the crust. This force is known as seismic waves. The seismic waves (P waves, S waves, Love waves, and Rayleigh waves) are the motion that we can feel, created by the earthquake.

The normal fault line is associated with divergent forces pulling 2 tectonic plates away, causing 1 plate to slide under the other. The thrust fault line is associated with convergent fault lines, when the action of 2 tectonic plates pushing into each other results in a build up of pressure and finally causes on plate to move above another. Alternatively, both plates at move up, gaining height (which is how mountains are formed). The Himalayas is between 2 convergent plates, and hence is still growing in height as time passes.

The more powerful earthquakes are commonly associated with the thrust fault line. The colliding forces of the 2 tectonic plates causes more elastic strain on the fault line, which results in a greater release of energy.

Earthquakes are measured based on the Richter scale, which is between 1 to 10, with 10 being devastating and 1 meaning the earthquake can only be detected by machine.

However, that being said, earthquakes can occur anywhere. Although earthquakes are more common along fault lines, there have been instances of inland earthquakes as well.

Answer 2

The epicenter of an earthquake is located on the earth's surface directly above the focus of the earthquake.

The focus is the point underground where the fault line started rupturing.

Answer 3

the middle of the earthquake is where the epicenter occur
Directly above the focus.

Answer 4

earthquakes commonly appears in places where there are faults.

Answer 5

Earthquakes actually occur all over the world. They occur in places along plate edges and along faults. California is known to have some of the most frequent earthquakes.

Answer 6

near a place where tectonic plate activity occurs

Answer 7

it is directly above the focus

Answer 8

on the surface, directly above the focus
