The Top-to-Bottom Structure of the Garlock Fault Zone Uncovered with Fiber Sensing
CONTROL OF FAULT ZONE HETEROGENEITY AND FAULT ROUGHNESS ON MULTISCALE DEFORMATION AT INTER- AND INTRAPLATE FAULT ZONES IV ORAL
tectonophysics | 15 december 2023
James Atterholt, Zhongwen Zhan, Yan Yang, Weiqiang...
The structure of fault zones and the ruptures they host are inextricably linked. Fault zones are narrow, which has made imaging their structure at sei...

Imaging the Garlock Fault Zone Using Distributed Acoustic Sensing
STRUCTURE, MECHANICS, AND HAZARDS OF GEOMETRICALLY COMPLEX FAULT SYSTEMS IV ORAL
tectonophysics | 13 december 2022
James Atterholt, Zhongwen Zhan, Yan Yang
Multi-scale fault zone structure largely controls the behavior of earthquake ruptures and encodes the long-term displacement history of the fault. Det...

Global Evaluation of Large Strike-Slip Ruptures Using a Bayesian Estimation of Stress Glut Second Moments
ADVANCEMENTS IN IMAGING EARTHQUAKE SOURCE PROCESSES I ORAL
seismology | 12 december 2022
James Atterholt, Zachary E. Ross
Earthquake ruptures are complex processes that may vary strongly according to the structure and tectonics of the region in which they occur. Character...

Fault Zone Imaging With Distributed Acoustic Sensing: Body‐To‐Surface Wave Scattering
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
17 november 2022
James Atterholt, Zhongwen Zhan, Yan Yang
Fault zone structures at many scales largely dictate earthquake ruptures and are controlled by the geologic setting and slip history. Characterizat...
