hypocentre
Earthquake's underground source
The hypocentre is the point within the earth where an earthquake originates—the actual location of rupture along a fault.
Distinguished from the epicentre, which is the point on the surface directly above.
Also spelled hypocenter.
The hypocentre was located twelve kilometres below the city.
