The hypocenter is the point within the earth where an earthquake rupture starts

The hypocenter is the exact location of the earthquakes origin, but where it occurs inside of the Earth. The epicenter is the spot on the Earths crust directly above where the hypocenter is. Or something like that.

A hypocenter can refer to a site of which a nuclear bomb explodes or the start point of an earthquake, below the surface where the energy is first accumulated and released. Just some extra information, right above the hypocenter, is the epicenter.

The epicenter is the point on the Earth's surface directly above the hypocenter (100's of miles), the hypocenter is where movement first occurs in the fault, and the epicenter is where we feel the quake (when it's its strongest).
