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 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.
Detailed explanation-3: -The point on the Earth’s surface that is directly above the focus is called the epicenter. The waves radiating through the Earth away from the focus can be recorded by an instrument known as a seismograph, which produces a record known as a seismogram.
Detailed explanation-4: -Epicenter. The point on the Earth’s surface directly above the focus or hypocenter of an earthquake (the point within the Earth where the earthquake originated).
Detailed explanation-5: -The epicentre is the worst affected area on the Earth’s surface when the earthquake occurs. The point inside the earth right under the epicentre is called the focus.
