Earthquakes and Seismic Waves

Dan Tingley, Angel Achar, and Nick Franco

fault
Fault
  • Fault - break in the rocks that make up the Earth’s crust
  • To be a fault, the rocks on either side must be moving
  • Sometimes the movement is sudden, and it causes an earthquake
focus and epicenter
Focus and Epicenter
  • Focus - the place in the Earth where the movement happens in an earthquake
  • Epicenter - the point on the Earth’s surface directly above the focus
seismic waves
Seismic Waves
  • Seismic waves are waves that travel through the Earth because of an earthquake
  • Two Kinds: Body and Surface waves

-Body travel inside the Earth

p waves
P-Waves
  • Primary Waves
  • P-waves travel through all the layers of the Earth
  • The fastest of all seismic waves
  • Squeeze and pull rocks in same direction as the movement of the wave
s waves
S-Waves
  • Secondary Waves
  • Cause the rocks to move at a right angle to the movement of the wave
  • Slower than P-Waves
surface waves
Surface Waves
  • Up and down, side to side movement
  • Travel along Earth’s surface
  • Cause the most damage in an Earthquake
