Earthquakes in complex fault settings: Examples from the Oregon Cascades, Eastern California Shear Zone, and San Andreas fault
… the creeping section of the San Andreas fault at Parkfield, CA to determine if it shifted in response to the M6 2004 Parkfield earthquake. I used an Iterative Closest Point algorithm to find the displacement between two lidar datasets acquired 13 years apart. I compared creep rates measured before …

Remote Sensing Big Data and Physical Models for Resilience to Geohazards in the Water-Energy Nexus
… hydrologic properties. Finally, I revisit the Parkfield Paradox on the San Andreas Fault, where the anticipated M6.0 earthquake occurred 16 years later than predicted. By integrating seismicity records, creep measurements, and long-term fluid injection data from the nearby San Ardo oil field, I …

Earth tides, earthquake occurrence and earth deformation
… The results for Earth<br/>displacements in the Parkfield area are less satisfactory but a number of<br/>interference fringes over a wide area due to a particular earthquake have been<br/>observed.

From Fault Dynamics to Seismic Hazard Assessment
… calculation. We applied this methodology to the Parkfield Segment of the San Andreas Fault, where the seismic cycle is particularly well documented. Our study implies potential maximum magnitude between 6.5 and 7.5, with a return period of 140 to 300 years. In Chapter 2, we applied the same …

Improving statistical seismicity models
… sequences (1992 Landers, 1999 Hector Mine, 2004 Parkfield). The tests show that the fault geometry is the most valuable information for improving aftershock forecasts. Furthermore, they reveal that static stress maps can additionally improve the forecasts of off--fault aftershock locations, while …

Seismic Investigation on Temporal Structural Changes and Joint Inversion of Sedimentary and Crustal Structure Beneath North China
… an active source cross-well experiment at Parkfield SAFOD drill site to verify the possibility of detecting stress-induced seismic velocity changes at the top part of seismogenic zone. Our result shows a ~0.04% S-wave variation that are strongly correlated with the fluctuation of barometric …

Improvement of aftershock models based on Coulomb stress changes and rate-and-state dependent friction
… the Mw 9.0 Tohoku megathrust and the Mw 6.0 Parkfield strike slip earthquake. I study aleatoric uncertainties using a Monte Carlo method. I find that the existence of multiple receiver faults is the most important source of intrinsic stress heterogeneity, and CRS models perform better when …
