GEOLOGY

Detailed explanation-1: -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 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. Sometimes the ground surface breaks along the fault. Sometimes the movement is deep underground and the surface does not break.

Detailed explanation-3: -The world’s greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet’s largest earthquakes occur. It has earned the nickname “Ring of Fire".

Detailed explanation-4: -An earthquake is the sudden movement of Earth’s crust at a fault line. The location where an earthquake begins is called the epicenter. An earthquake’s most intense shaking is often felt near the epicenter.

Detailed explanation-5: -The epicenter is on the earth’s surface directly above the focus where seismic waves originate. The damage caused by an earthquake is more severe when an area is closer to the epicenter of the earthquake as the intensity will be greatest/vibration strongest.
