What is the definition of an epicentre of an earthquake?

Answer 1

The epicentre of an earthquake is the point on the earth's surface away from which the seismic waves produced by an earthquake radiate. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water.

As such the epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).

Answer 2

The epicenter of an earthquake is the point on the Earth's surface directly above where the earthquake starts. It is usually the point where the seismic waves are strongest and causes the most damage.

Answer 3

Epicentre is the originating point of athing

e.g the epicentre of an earthquake is the point where it started

Answer 4

Definition of an epicentre:

The epicentre of an earthquake is the point directly about the focus on the earth's surface.

The epicentre is where the earthquake took place

Answer 5

an epicentre is the part of an earthquake directly above the fault line. a fault line is the bit where the two plates rub together.
