GP218 - Methods of Earthquake Source Modeling

This seminar course is designed as a forum to discuss the relevent literature on the various methods of earthquake source parameter retrieval. Topics of particular interest include seismic moment tensors, linear vs non-linear inversions, time dependent moment tensors, and multiple-point source models. Although focus is on reviewing papers discussing the use of waveforms to extract source parameters, amplitude methods are also compared. The second half of the course is designed to review and evaluate the various methods used to determine finite, or distibuted seismic source models utilizing local strong-motion, regional broadband and broadband teleseismic data sets. Comparisons will be made between the various seismologically and geodetically derived source models. The primary purpose of this course is to become familiar with the various methodologies and to gain insight and understanding of the resolution and uncertainties characteristic of each method.
