Seismology and Acoustic-Gravity Waves

Abstract

The report deals with the development of a systematic approach of determining the dislocation or relative displacement on the fault surface from a limited set of observed surface displacement data with their estimated errors. The technique gives not only a best fit dislocation model but allows one to determine the reliability of the model and the resolving power of the data set. The resulting dislocation model can then be used to extrapolate the surface displacements outside of the data set. The report also deals with the applications of the inversion technique to the change in surface displacement data caused by deformation resulting from the 1964 Alaska earthquake. For this earthquake, a two-dimensional finite element numerical model is used to calculate surface displacements from a dislocation imposed on a fault surface located in a heterogeneous medium.
