The Weingarten Lab @SDSU uses hydrogeologic, geophysical and geomechanical data to build computational models of the interaction between fluids and faults in the subsurface. Our specific emphasis aims to understand how fluid-fault interaction is involved in a variety of geologic problems -- including geohazards such as natural and induced seismicity.
Research Topics:
Induced SeismicityWe investigate the physics of injection-induced seismicity using computational models. Typically these studies involve hydrogeologic, geomechanical and seismic data. One goal of our lab is to develop tools to better mitigate injection-induced seismicity (fig. from Justin Rubinstein, 2018) |
Fluid-Fault InteractionOur group studies fluid-fault interaction from the fault damage zone to the regional-scale. These studies involve the use of hydrogeologic, seismic and structural geologic data. *(figure from Hill et al., 2023) |
Dynamic PermeabilityPermeability is a fundamental parameter in a multitude of geologic processes and can vary over 16 orders of magnitude. We study the static and dynamic nature of crustal permeability using hydrogeologic, geologic and geomechanical data. *(figure from Hung & Weingarten, 2023) |
