Presentation Transcript

  1. Summary of seismology component of the course • Sources • Waves • Location • Magnitude/Intensity • Focal mechanisms • Other topics

  2. Sources • source models • Double couple forces • Moment tensors

  3. Waves • Notation (teleseisms) P, S = mantle phases K = outer core P wave I,(J) = inner core P and S c = reflection from the outer core pP, sP = reflections from the earth surface near the source (Lower case = reflection) PKP = P wave in mantle, outer core, mantle PcP = Mantle phase reflected from the outer core

  4. Waves • Notation (local) • Pg • Pn • P* • Near field / Far field

  5. Location • General principles • Station corrections • depth control

  6. Magnitude and Intensity • Mw, Mwp, ML, Mb, etc. • Intensity scales

  7. Focal Mechanisms Fault Plane Solutions of Earthquakes, Northeast India Kayal et al., 2006

  8. Other topics • Hazards and damaging effects, • prediction and forecasting, • instruments, networks, arrays, etc.
