GEOLOGY

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. Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows.

Detailed explanation-3: -The hypocenter is the true location of the earthquake at depth, while the epicenter is merely a point on the earth’s surface. Seismographs are devices that are used to measure ground motion caused by earthquakes. Scientists can use seismographs and seismic wave arrival times to find the epicenter.

Detailed explanation-4: -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.

Detailed explanation-5: -The epicenter, epicentre or epicentrum is the point on the Earth’s surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates.
