Question

The point on, Earth's surface directly above the focus is the .........

• A. pole
• B. circumcenter
• C. origin
• D. epicenter

Answer 1

The correct option is D epicenter

The point on, Earth's surface directly above the focus is the epicenter.
The epicenter, epicentre or epicentrum is the point on the Earth's surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates. In the case of earthquakes, the epicenter is directly above the point where the fault begins to rupture, and in most cases, it is the area of greatest damage. However, in larger events, the length of the fault rupture is much longer, and damage can spread across the rupture zone.
