Detailed explanation-1: -The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.
Detailed explanation-2: -The spot underground where the rock first breaks is called the focus, or hypocenter of the earthquake. The place right above the focus (at the ground surface) is called the epicenter of the earthquake.
Detailed explanation-3: -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-4: -Pressure builds, and when the plates finally give and slip, energy is released as seismic waves, causing the ground to shake. This is an earthquake. 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.
Detailed explanation-5: -The point where an earthquake originates is called the seismic focus. It is also known as hypocenter.
