Many fault lines are obvious at the surface. How can the epicenter of an earthquake be located miles away from the fault line?

• The epicenter is the place of greatest damage, and it can be miles from the site of the earthquake.

• The earthquake happened at a place where there is no fault, so the epicenter is not near a fault line.

• Some large earthquakes have more than one epicenter, and these epicenters can be far from the fault line.

• The fault line does not extend straight down from the surface, so the focus is not directly beneath the point where the fault reaches the surface.

Which statement is not true:

• Ground movement occurs when Earth layers move suddenly and release energy.

• The release of energy sends seismic waves out from the focus point of the Earth quake.

• Epicenter is the spot directly above the focus of the Earth’s surface.

• Earthquakes only affect a small area when one occurs.
