Javel, du ønsker å konstruere noen seismografer, kople disse i et nettverk og estimere jordskjelv magnityder og -lokaliseringer, og deretter dele dine data med andre ...

Du trenger noen lærebøker. Vi foreslår:

• C.M.R. Fowler: "The Solid Earth", ISBN: 0521385903
• W. Kenneth Hamblin, Eric H. Christiansen: "Earth's Dynamic Systems", 9th edition, Prentice Hall; ISBN: 0130183717
• Peter M. Shearer: "Introduction to Seismology", Cambridge University Press, ISBN 0-521-66953-7
• Thorne Lay, Terry C. Wallace: "Modern Global Seismology", Academic Press, ISBN 0-12-732870-X

1. Lese seismogrammer

• Background I: The structure of the Earth
  • Origin and Structure of the Earth, on-line course material, "GEOL-111 Planet Earth", Department of Geological Sciences and Environmental Sciences, State University of New York at Binghamton
  • Earth Cutaway, by the Geothermal Education Office
  • Peliminary Reference Earth Model (PREM), by Anderson og Dziewonski. Use these data to plot P-wave (alpha) and S-wave (beta) velocity as a function of earth radius. What happens to beta in the outer core, and why?
• Background II: Seismic waves
  • Types of Seismic Waves, UPSeis program, Department of Geological Engineering and Sciences, Michigan Technological University.
  • Seismic Waves: A program for the visualization of wave propagation, by Alan L. Jones. For Windows. Download and install this program - it's really a source of insight.
• Tracing and Naming Waves, Princeton Earth Physics Project (PEPP)
• Seismic Waves, PEPP
• How Do I Read a Seismogram?, UPSeis program, Department of Geological Engineering and Sciences, Michigan Technological University.

2. Beregne magnityder og bestemme lokaliseringer

• Earthquake Magnitudes, PEPP
• MichSeis Newsletter Vol. 2, No. 4, Winter, 1995: Things to do...: Surface wave magnitude
• Intensity and intensity scales. From the draft version of the "New Manual of Seismological Observatory Practice" (NMSOP) , ch. 12 (15?).
• Virtual Earthquake: An interactive Web-based program, Department of Geological Sciences, California State University.
• United States Geological Survey (USGS): Finding an earthquake's location with modern seismic networks
• How Do I Locate That Earthquake's Epicenter? UPSeis program, Department of Geological Engineering and Sciences, Michigan Technological University.
