Earth and Environmental science Year 11 Revision 4

What is an epicenter? 

• Where an earthquake started
• The surface right above where an earthquake started 

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

P-wave 

• The center of a earthquake. 
• Also know as shear or secondary wave. 
• Always the first to arrive;  seismic wave that causes particles of rock to move in back-and-forth direction
• Hilbert
