DISTINGUISH BETWEEN THE FOCUS AND THE EPICENTER OF AN EARTHQUAKE!

$\large\fcolorbox{black}{lime}{Itzraisingstar's \: AnsweR:}$

First, let us know what is meant by Focus and Epicentre!

Focus of an Earthquake:

Focus is the first point of movement along a fault where all earthquake waves originate - it is below the surface. The epicenter is the point on the surface above the focus - the place on the surface that would receive the most intense vibrations.

Scientists can also use seismograph data to locate the focus of an earthquake. They study seismograms to identify waves that have reflected off boundaries inside Earth. Some of these waves help scientists to determine the earthquake's depth. A seismogram records the time when the first primary wave arrives.

Epicenter of an earthquake:

The location inside the Earth where an earthquake begins is called the focus (or hypocenter) of the earthquake. The point at the Earth's surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.

Difference between Focus and Epicenter?

The point inside the crust where the pressure is released is called the focus. The point on the Earth's surface above the focus is called the epicenter. Earthquake energy is released in seismic waves.
