Question

The point of origin of an Earthquake is called the
a. epicentre b. focus
c. seismic wave d. magnitude

Answer 1

The point of origin of an Earthquake is called there b. focus.

The point where an earthquake originates is called seismic focus.

It is just above the earth’s epicenter on the earth’s surface.

The focus is also known as hypocenter of an earthquake and here at this point ground ruptures.

As the ground breaks down, the vibrating waves travel away from the focus of the earthquake outwards in all directions.

Answer 2

Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.

The epicentre of an earthquake is known as the b. focus.

Seismic focus refers to the location where an earthquake begins.

It is just above the earth’s epicentre on the earth’s surface.

The focus is also known as hypocenter of an earthquake and here at this point ground ruptures.

As the ground gives way, the vibrating waves spread outwards in all directions, away from the epicentre of the earthquake.
