1. Perturbed seismicity by known stresses
The response of seismic activity to known stress perturbations can shed light on the physical mechanisms of earthquake generation and physical properties controlling fault behavior. We investigate how seismic activity responds to periodic stress perturbations over a range of frequencies to understand the frequency-dependent earthquake triggering and constrain critical physical properties of fault systems.
2. Hydrogeological processes inside fault zones
We study how earthquakes affect hydrogeological processes from two perspectives: fault zone hydrogeological architectures and hydrological responses to earthquakes.
Induced seismicity serves as a natural laboratory for learning how fluids affect earthquake generation, providing valuable insights into earthquake physics and hazard estimation. We investigate how hydraulic fracturing triggers earthquakes through both observational and numerical simulation perspectives to have a better understanding of the fundamental mechanisms of induced seismicity and to develop physics-based models for earthquake forecasting.
4. Crustal deformation during earthquake cycles
Understanding fault slip behaviors during interseismic, coseismic, and postseismic periods is important to learn how tectonic stresses are accumulated and released in the fault system, which is fundamental to understanding fault behaviors during earthquake cycles and to improving earthquake hazard estimation. We study the ground deformation during earthquake cycles by using InSAR and GNSS.
