Earthquakes

where quake begins below surface

• elastic rebounding

• focus

• epicenter

• fault

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

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

• P waves
• S waves

Most earthquakes happen along the _________________. 

• coast
• faults
• desert
• directions

A tracing of earthquake motion that is created by a seismograph. This can be on a huge sheet of paper, shows P-waves

• Seismic wave
• Carrollton 
• Deformed 

Seismology

• Branch of science that studies earthquakes 
• Earthquakes 
• The sudden return to elastically deformed rock to its original shape. 
• Focus 

Many earthquakes happen along the borders of...

• Countries
• Tetonic Plates
• Climate Zones
• None of the above.

Second waves to arrive that cause earthquakes

• P waves
• S waves
• Surface waves

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