Question

Quizplus · Accepted Answer

The initial rupture point of an earthquake below Earth's surface is known as the focus. This is the point where the seismic energy is first released, and it is usually located several kilometers beneath the Earth's surface. The epicenter, on the other hand, is the point on the Earth's surface directly above the focus, and the disaster zone refers to the area that has been impacted by the earthquake. The seismic center is not a commonly used term in seismology.
