EARTHQUAKES & VOLCANOES

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

This famous transform fault is located in the western United States creates significant earthquake activity for California

• New Madrid
• Denali Fault
• Ramapo Seismic Zone
• San Andreas

The Richter scale measures:

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

Which travels fastest, always being the first detected by seismic stations?

• P waves
• S waves
