 Introduction to Seismology The wave equation and body wavesPeter M. ShearerPDF | 39 Pages | EnglishSeismology is the study of earthquakes and seismic waves and what they tell us about Earth structure. Seismology is a data-driven science and its most important discoveries usually result from analysis of new data sets or development of new data analysis methods. Most seismologists spend most of their time studying seismo-grams, which are simply a record of Earth motion at a particular place as a function of time. Instrumentation in Earthquake SeismologyJens Havskov, Gerardo AlguacilPDF | 313 Pages | English The ability to do earthquake location and calculate magnitude immediately brings us into two basic requirement of instrumentation: keeping accurate time and determining the frequency dependent relation between the measurement and the real ground motion. Basics of Seismic Wave TheoryGerard T. Schuster, University of UtahPDF | 154 Pages | EnglishThese are the notes for the 5-day course ”Basics of Seismic Wave Theory” presented at Capetown University in April, 2007. They are intended as a supplement to the lectures and provide the advanced undergraduate and 1st-year graduate student with a basic understanding of seismic wave theory. The applications are for both earthquake and exploration seismology, but the emphasis is on exploration geophysics. The lectures begin with an overview of seismology with applications to both earthquake studies and exploration geophysics. This is followed by discussions of the physics of acoustic and elastic wave propagation. Topics to be covered include the stress-strain relations, the wave equation, solutions to the two-layer problem, wave types such as P, SV, SH, Rayleigh, and Love, Snell’s law, the eikonal equation, Green’s theorem, reflection and transmission coefficients, wavefronts, rays, head waves, AVO, wavelength, energy, and attenuation. These principles will be used to understand the imaging concepts of travel time tomography and waveform migration.
