what is a seismic wave
What is a Seismic Wave?
  • Waves that originate from collision of 2 tectonic plates
  • Measured by a seismograph
the types of waves
The types of waves
  • Three types of waves
  • P waves
  • S waves
  • L waves
p waves
P waves
  • P stands for primary
  • Classified as a body wave
  • P waves are the first waves to occur
  • Originate from epicenter( the center of shock)
  • Faster than S waves
  • Can pass through solids, liquids, and gases
p waves1
P waves
  • Longitudinal waves
  • Ground crumbles when P waves hit surface
  • Travel 6.0 km/s or 3.7 mi/s
s waves
S waves
  • S stands for secondary
  • Comes second after P waves
  • Classified as a body wave
  • Transverse waves
  • Originate from epicenter (center of shock)
  • Can only pass through solids
l waves
L waves
  • Also called love waves
  • Named after scientist A.E.H. Love
  • Classified as surface waves
  • Travel along Earth’s surface
  • Most destructive wave
  • Slowest of all waves
  • Originate from hypocenter
