Earthquakes

How does distance from the epicenter of an earthquake change the earthquake’s effects?

• The strongest effects are at the epicenter.

• The strongest effects are felt furthest from the epicenter.

• The strongest effects are felt in a line extending north and south from the epicenter.

• The strongest effects are in a ring surrounding the epicenter with a radius of several miles.

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.

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.
