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
