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: -For instance, seismic waves carry energy from the source of the shaking outward in all directions (not in one direction only as the setup shows). 7. (Optional) Both primary and secondary waves are body waves (pass through the interior of the Earth). Surface waves travel along the Earth’s surface.

Detailed explanation-3: -As seismic waves travel away from the focus they decrease in energy & intensity. Why does the most damage occur close to the fault? The most damage occurs close to the fault because it is where the greatest amount of energy is found.

Detailed explanation-4: -Body waves. Body waves radiate outward from the focus in all directions and travel through solid rock.
