  1. Illinois EarthScope 2010 A Teacher Workshop Integrating Math, Science, and Technology Robert S. Nelson, Eric Avalos, HridayaBastola, Brianne Jacoby Illinois State University Normal, Illinois November 3, 2010, Denver, Colorado Geological Society of America

  2. Acknowledgements EarthScopeis funded by the National Science Foundation. EarthScope is being constructed, operated, and maintained as a collaborative effort with UNAVCO, IRIS, and Stanford University, with contributions from the USGS, NASA, and several other national and international organizations.

  3. How thick is the earth’s crust?

  4. Where? Midwest - southern Illinois area

  5. Andrija Mohorovicic (1857-1936) discovered this change in seismic velocity when he examined the primitive seismograms from the October 8, 1909 Kupa Valley Earthquake. • The epicenter of the earthquake was about 39 km southeast of Zagreb, Croatia.

  6. The Mohorovicic Discontinuity, or "Moho", is the boundary between the crust and the mantle. • At the Mohorovicic Discontinuity the P-wave velocity increases from under 7 km/sec for the crust (granite like materials) to over 8 km/sec for the mantle (basalt like materials)

  7. Science • Energy source • Passive (earthquake) • Active (explosives) • Midcontinent seismogensis

  8. Kim (2003). Midcontinent Seismogenic Areas Wabash Valley Seismic Zone New Madrid Seismic Zone Adopted from Kim 2003

  9. Technology • Exploration Seismometer • Seistronics RAS 24 • Advanced National Seismic System • HDIL Backbone Seismic Station • IRIS Site

  10. Seismic Ray Pathssimple two layer case

  11. Mathamatics

  12. Simple Refraction 1 / V2 1/V1 Time (miliseconds Distance (meters)

  13. Mathematics Refraction Solutionusing cross-over distance

  14. Z = 40.05 km
