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 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. There are two ways by which we can measure the strength of an earthquake: magnitude and intensity.

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 place where a fault ruptures is called the focus or origin, and the point directly above on the earth’s surface is called the epicentre. The pulse of energy released by a fault movement radiates outwards as seismic waves, or shock waves.
