Best Answer

In regard to earthquakes:

The epicenter is a point on the earth's surface directly above the focus of the earthquake.

The focus is the underground place where the earthquake suddenly started, with rocks fracturing along a fault line and releasing seismic energy waves.

In ordinary English:

The word epicenter means the center or focal point of some dramatic or dangerous events.

Focus is the point of interest or activity, such as the point where light rays meet. To focus is to give your full attention to an activity or problem.
