What is the difference between the focus and the epicenter of an earthquake?
A
Focus is the specific point, epicenter is the surrounding area
B
Epicenter is the specific point, focus is the surrounding area
C
Focus is underground, epicenter is on the surface
D
Epicenter is underground, focus is on the surface
Explanation: 

Detailed explanation-1: -The focus is point inside the earth where the earthquake started, sometimes called the hypocenter, and the point on the surface of the earth directly above the focus is called the epicenter. There are two ways by which we can measure the strength of an earthquake: magnitude and intensity.

Detailed explanation-2: -The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.

Detailed explanation-3: -The point on the surface of the earth which is vertically above the focus is called the epicentre. It is the first place to experience the waves.

Detailed explanation-4: -Epicenter is the location on the surface of the Earth directly above where the earthquake starts. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts.

Detailed explanation-5: -the focus of an earthquake is the point at which the first movement occurs. the epicenter of an earthquake is the point on earth’s surface directly above the focus of an earthquake.
