The location on the surface of the Earth immediately above the origin of a fault is called the epicenter.

Here's a breakdown:

* Fault: A fracture or zone of fractures in the Earth's crust where rocks have moved past each other.

* Origin: The point where the fault rupture begins.

* Epicenter: The point on the Earth's surface directly above the origin of the fault, where the seismic waves from an earthquake are felt most strongly.
