  1. Classical Seismology • Global Seismology • Use energy released by earthquakes (or nuclear tests) to image Earth’s deep interior Source: http://www.mantleplumes.org

  2. Classical Seismology • Global Seismology • Use energy released by earthquakes (or nuclear tests) to image Earth’s deep interior Source: http://www.mantleplumes.org

  3. Classical Seismology • Crustal seismology • Use active sources (explosives, vibroseis trucks) or earthquake energy to image Earth’s crust (< 50-70 km) Source: Levander, A., Understanding crustal complexity in seismic images: http://serc.carleton.edu/html/ROL/levander.htm

  4. Classical Seismology • Exploration Seismology • Use active sources to investigate hydrocarbon reservoirs (< 10 km)

  5. Seismic Refraction L1 L2 From Langston, 1992 Refraction Traveltime Equation:

  6. What about multiple layers? • Works for increasing velocities (v1 <v2 …) • Low velocity layers are “hidden” From Langston, 1992

  7. Wave Propagation in Acoustic Media

  8. Wave Propagation in Elastic Media

  9. Seismic Reflection L1 L2 Reflection Coefficient:
