Where is the epicenter of this hypothetical earthquake

The epicenter of a hypothetical Earthquake is the place where the fault begins to rupture. The tectonic movements within the epicenter is actually the area with the greatest damage after an Earthquake occurs.

The epicenter is the most dangerous zone during an Earthquake because the ground is very much unstable, but as the seismic activity dissipates it is the first one to set and stabilize because this is where the plates will converge.
