The earthquake feature that lies directly below the epicenter is known as the focus (Option A).
What earthquake feature lies directly below the epicenter?
Directly below the epicenter of an earthquake lies the focus. The epicenter is the point on the Earth's surface directly above the earthquake's point of origin, which is the focus.
The focus is the actual location where the seismic energy is released, typically deep within the Earth's crust or upper mantle. So, if you were to draw a straight line from the epicenter through the Earth's interior, you would reach the earthquake's focus.
