An earthquake's epicenter is (1 point)the place on earth's surface directly above the focus a spot halfway between the focus and the surface the spot below the focus any spot along the nearest fault 2. when an earthquake occurs, energy radiates in all directions from its source, which is called the (1 point)epicenter focus fault seismic center 3. earthquakes are usually associated with (1 point)violent weather faults large cities

An earthquake's epicenter is the place on earth's surface directly above the focus.

reason : the epicenter lie above the focus  where the disturbance starts.

when an earthquake occurs, energy radiates in all directions from its source, which is called the focus

reason : because the disturbance starts from the focus below the epicenter.

earthquakes are usually associated with faults

reason : earthquake arise from the disturbance or faults of the plates of the earth inside.

v=uf/(u-f)
