**Text: ** Introduction to Seismology (2nd edition) by Peter Shearer. Likely chapters 4-7. It is available here under UCSD license

This course is intended as an introduction to exploration seismology. Our goal is to provide a general overview of the basics of exploration seismology. The emphasis will be practical (how things are actually done), rather than on detailed theory or derivations. This year we will focus on processing the data acquired in the experiment and derive the necessary theory for doing so.

Call the files LastName_ExXX. If I ask to redo some part of do it fast.

Homework is due 8am on Wednesday. That way we can discuss in class.

- (due April 3) Read Chapters 1-3, come and ask one seismic question.
- (due April 9) Exercise 2.3 (dont do next year), 3.7 (computer), 4.1
- (due April 18) Exercise 4.9 (computer). For 4.9 use the attached layerxt. raytracer
layerxt.m, velocity model
PREM.

Assuming a uniform spherical earth (choose good parameters), compute the P, PP, and PKP traveltime curves. Discuss the results (where does it fail...). - (May 16) Exercise 5.2
- (May 30) Chile Earthquake: Group 1:Plot seismograms, band-filtered; compare with theoretical travel times Use TA or other arrays Chile Earthquake: Group 2: Beamform using TA to get slowness spectra
