Reading Waves

Using Seismic Data


  • Vibroseis units similar to this are common as sources in land reflection seismic surveys – They substitute for explosives –several are used together - radio controlled and synchronized


Refracted Wave


Waves used in reflection seismology


  • The inverse slope of the line starting at 0,0 will give the velocity of the direct wave.

  • The inverse slope of the straight line events shown will give the velocities of the refracted waves in the layers.


Equations for finding the thickness of the layers

  • ic0 - critical angleV0 - velocity of the first layerV1 - velocity of the second layerh0 - thickness of the first layerT01 - intercept
