  1. Reading Waves Using Seismic Data

  2. 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

  3. Refracted Wave

  4. Waves used in reflection seismology

  5. 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.

  6. 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

  7. Waves used in reflection seismology

  8. Sample Data from the Workshop

  9. Cropped Data
