Perturbation Kernels for Generalized Seismological Data Functionals (GSDF)
Author(s):Chen, Po; Jordan, Thomas H.; Lee, En Jui; Chen, Po; Jordan, Thomas H.; Lee, En Jui
In seismic waveform analysis and inversion, data functionals can be used to quantify the misfit between observed and model-predicted (synthetic) seismograms. The generalized seismological data functionals (GSDF) of Gee & ...
Rapid Full-Wave Centroid Moment Tensor (CMT) Inversion in a Three-Dimensional Earth Structure Model for Earthquakes in Southern California
Author(s):Lee, En Jui; Chen, Po; Jordan, Thomas H.; Wang, L.; Lee, En Jui; Chen, Po; Jordan, Thomas H.; Wang, L.
A central problem of seismology is the inversion of regional waveform data for models of earthquake sources. In regions such as Southern California, preliminary 3-D earth structure models are already available, and efficient ...
Automating Seismic Waveform Analysis For Full 3-D Waveform Inversions
Author(s):Lee, En Jui; Chen, Po; Lee, En Jui; Chen, Po
We present a semi-automatic seismic waveform selection algorithm that can be used in full 3-D waveform inversions for earthquake source parameters and/or earth structure models. The algorithm is applied on pairs of observed ...
Resolving Fault Plane Ambiguity for Small Earthquakes
Author(s):Chen, Po; Lee, En Jui; Jordan, Thomas H.; Zhao, L.; Chen, Po; Lee, En Jui; Jordan, Thomas H.; Zhao, L.
We have developed an automated procedure to resolve fault-plane ambiguity for small to medium-sized earthquakes (2.5 ≤ ML ≤ 5) using synthetic Green's tensors computed in a 3-D earth structure model and applied this procedure ...
