Xiaozhuo Wei

Xiaozhuo Wei is a Postdoctoral Scholar Research Associate in Geophysics at the California Institute of Technology (Caltech), affiliated with the Division of Geological and Planetary Sciences and the Department of Geophysics. His research focuses on geophysical monitoring of volcanic and tectonic processes, employing advanced techniques like fiber-optic geodesy, seismic tomography, and machine learning. He specializes in studying seismicity associated with volcanic eruptions, magma dynamics, and slow slip events in subduction zones, with significant contributions to understanding the 2018 Kīlauea eruption and Iceland's Reykjanes Peninsula eruptions.

• Key affiliations: Caltech’s Geophysics Department, Division of Geological and Planetary Sciences
• Research tools: Distributed Acoustic Sensing (DAS), ambient noise tomography, and offshore seismic arrays
• Field areas: Kīlauea Volcano (Hawaii), Iceland’s Reykjanes Peninsula, and Alaska’s subduction zones

Wei’s work integrates multidisciplinary approaches to investigate crustal deformation, magma storage, and seismic hazard assessment. He has contributed to improving earthquake catalogs using offshore data and analyzing post-eruption seismicity patterns. His recent studies explore the spatial-temporal evolution of volcanic systems and the mechanics of dike intrusions using high-resolution geophysical methods.

His research emphasizes real-time monitoring of volcanic processes and has advanced understanding of how seismic velocity changes reflect magma movement. Collaborations involve deploying ocean-bottom seismometers and machine learning algorithms to detect slow slip events in subduction zones, enhancing earthquake prediction capabilities.

Notable projects include the 2023–2024 Reykjanes eruptions study and the analysis of the 2018 Kīlauea eruption’s seismic aftermath. His work bridges observational seismology with theoretical models of volcanic and tectonic systems, contributing to both fundamental science and practical hazard mitigation strategies.
