The focus is the point within Earth where the earthquake starts and the epicenter has nothing to do with earthquakes.

Detailed explanation-1: -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-2: -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.
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: -Focus is the first point of movement along a fault where all earthquake waves originate-it is below the surface. The epicenter is the point on the surface above the focus-the place on the surface that would receive the most intense vibrations.
Detailed explanation-5: -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.
