Seismo Lab Seminar

Geofluids at varying depths play fundamental roles in Earth's dynamic processes, from driving volcanism and hydrothermal eruptions to sustaining groundwater resources. Imaging and monitoring these fluids provide critical insights into tectonic processes, geohazards, and resource management. In this presentation, I will highlight several projects conducted by our group using temporary passive seismic geophone arrays to investigate geofluid dynamics across a wide range of spatiotemporal scales. At larger scales, we deployed seismic arrays across the Denali Volcanic Gap and Yellowstone to image magmatic structures and better understand crustal magma storage and transport. At smaller scales, we examined Yellowstone's hydrothermal systems, exploring how internal and external forcing mechanisms regulate the dynamics of eruptive features such as geysers and thumping hot springs. More recently, we have begun exploring how passive seismology can be applied in Utah, from mountain catchments to the Salt Lake Valley, to monitor groundwater systems and quantify their responses to seasonal hydrologic forcing, including snowmelt and evapotranspiration. Together, these studies demonstrate the versatility of passive seismic methods for imaging and monitoring geofluids across diverse geological environments and scales.
