Ergodicity And Seismicity Clustering With Applications In Statistical Seismology, Nelson Cho

Electronic Thesis and Dissertation Repository

The implications of understanding fault networks as ergodic systems are addressed here by using the Thirumalai-Mountain metric that identifies effective ergodic periods, when long but finite time intervals are considered. This framework was proven to be useful in statistical seismology studies. Initially, it was established that that the metric can be used to quantify seismicity clustering. Periods of effective ergodicity were characterized by the occurrence of declustered seismicity. This interpretation was implemented for synthetic and seismic data from southern California and Canadian mines.

Next, methods used in the estimation of regional seismic hazard were applied to mining induced seismicity. The …
