Huiyun Guo

Huiyun Guo is a Research Fellow in Geophysics at the California Institute of Technology (Caltech). She holds an affiliation with the Department of Geophysics, focusing on fault zone dynamics, earthquake triggering mechanisms, and hydrogeological interactions in seismically active regions. Her research integrates seismological field data, geologic observations, and hydrologic modeling to understand fault behavior and stress variability.

Key research interests include fault maturity's influence on earthquake patterns, hydraulic properties of fault zones measured via tidal responses, and high-resolution analyses of earthquake triggering using dense seismic networks. She has contributed to studies in southern California, Japan, and other tectonically active regions.

Publications span 2018–2024, emphasizing fault zone hydraulics, dynamic triggering processes, and novel methods for seismic signal analysis. No awards or grants are explicitly listed in the provided texts. She currently advises no students but collaborates with senior faculty like Emily Brodsky and Masatoshi Miyazawa.
