Systematic Analysis of Historic Seismicity and Geodetic Measurements
Abstract
Large, extended fault systems are known to demonstrate complex space-time seismicity patterns which include, but are not limited to, repetitive events, precursory activity and quiescence, and aftershock sequences. Here we compare the results of an in-depth study of the southern California fault system using a pattern informatics (PI) analysis of seismicity, GPS measurements, and sequential InSAR images of the same region. The PI methodology (Tiampo et al., 2002) has been employed in the past to isolate emergent regions of coherent, correlated seismicity prior to their occurrence. Here it is associated with regions of anomalous stress and strain that can be quantified with local and regional geodetic measurements.
