Conduct research to develop novel computational approaches on earthquake source characterization using full waveform inversion or combination of similar inversion methodologies. The goal is to be able to minimize earthquake source location uncertainty using existing methods, to estimate source intensity and directionality characteristics, and to develop new methods that may require the joint estimation of additional subsurface geophysical parameters. To comparatively assess the effectiveness of different methods in earthquake source characterization, when the earth model is heterogeneous and isotropic/anisotropic, and for different subsurface conditions. The results could be integrated in TexNets operational process for earthquake location and a regional time-dependent seismic hazard model estimating approaches for risk mitigation.Present in meetings and conferences.Publish in peer review journals
