Text: Introduction to Seismology (2nd edition) by Peter Shearer. Likely chapters 4-9. It is available here under UCSD license

This course is intended as an introduction to seismology. Our goal is to provide a general overview of the basics of seismology. The emphasis will be practical (how things are actually done), rather than on detailed theory or derivations.

Assignments

    (due April 3) Read Chapters 1-3, come and ask one seismic question.
    (due April 12) Exercise 2.3, 3.7 (computer), 4.1

    (due May 2) Exercise 2.3, 3.7 (computer), 4.1
    (due May 9) 4.4 , 4.9 (computer). For 4.9 use the attached layerxt raytracer layerxt.m PREM
