If you want to know what the name is, it is called the epicenter. If you want to know a location where all earthquakes originate, there isn't one. Earthquakes can occur along faultlines, or in the middle of a continent.
Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
Plutonic earthquakes are deep focus earthquakes.
Shallow focus earthquakes generally cause more damage.
