it is the FAULT
Earthquake
It is the point within the Earth's crust where the fault movement or rupture actually occurs.
Faulting is when rocks deform in a brittle fashion and break, and then movement occurs along these fractures.

It's the "Fracture Center". The Epicenter is the spot directly above the earth that is the center of the earthquake.
Rupture or fault.
The focus (more correctly termed the hypocenter) of an earthquake is the point in the earth where the earthquake rupture or fault movement actually occurred. The point on the surface directly above the hypocenter is known as the epicenter.
Fault rupture about 14km long alone the southern edge of the city.
The movement of the crust along a thrust fault is usually a reverse movement unlike the movement along a normal fault.
The movement of the crust along a thrust fault is usually a reverse movement unlike the movement along a normal fault.
Because earthquakes rupture sections of a fault, sometimes for hundreds of miles. So it is possible for there to be just as much destruction anywhere along the fault as there is at the epicenter. (the epicenter being at the beginning of the rupture)
