seismic waves

• ･Body Wave

  • Traveling through the interior of the earth
• body wave

  • Arrive before the surface waves
• body wave

  • Higher Frequency
• P-Waves or Primary Waves

  • Fastest kind of seismic wave
• p waves is

  • 1ST to arrive at a seismic station
• p waves

  • Can pass through solid and liquid layers of the Earth’s interior
  • They are longitudinal waves they compress and Expand like a spring in the direction of the wave propagation
• S- Waves or Secondary Waves

  • Slower than P-Waves
  • Can only pass through solid layers of Earth’s Interior.
• S- Waves or Secondary Waves

  • Transverse Waves that rise and fall perpendicular to the direction traveled by the waves
• S- Waves or Secondary Waves

  • Similar to a rope shakes up and down
  • As it travels through liquid layers it stops
• Surface Waves

  • Travels only through the crust
  • Lower frequency than body waves
  • Arrive after body waves
• Love Waves

  • Fastest Surface wave
• • Love Waves

  Moves the ground from side to side

  • Produce entirely horizontal motion
• Rayleigh wave

  • Rolls along the ground just like a wave rolls across an ocean
• • Rayleigh wave

  Moves the ground up and down and side to side
