The epicenter of an earthquake is

• The point below the surface where rock begins to break and the first motion occurs
• The seismic station closest to the earthquake
• The place where the greatest damage occurs
• The point on the surface directly above the focus

The Richter scale measures:

• the amount of radon gas released
• the damage caused
• the strength of an earthquake
• the weight of tectonic plates

The focus of an earthquake is

• The point (below Earth's surface) where rock breaks
