Postdoctoral Researcher in Seismology at UC Davis
Amanda Thomas
Postdoctoral Researcher in Seismology
The University of California, Davis seeks a postdoctoral researcher to investigate low-frequency earthquakes (LFEs) associated with slow slip processes. The postdoc will work closely with PI Amanda Thomas (UC Davis) and David Shelly (USGS) to develop and apply new methods for automating detection and location LFEs in large seismic datasets.
Low-frequency earthquakes are low-amplitude seismic signals embedded within tectonic tremor and provide important insight into deformation occurring in the deep roots of faults. However, they are generally challenging to detect and are typically identified using template matching and large-scale cross-correlation approaches. As such, only a limited number of LFE catalogs exist, which hinders our ability to fully characterize their spatial and temporal distribution. The proposed research will explore new strategies for large-scale, systematic detection of LFEs across Cascadia and along the San Andreas Fault system, leveraging modern computational and data-driven approaches. These observations will improve constraints on slow slip processes, illuminate the structure and evolution of deep fault zones, and help clarify the relationship between slow slip and earthquakes, with broader implications for understanding fault mechanics and seismic hazard.
This position offers an opportunity to work at the intersection of observational seismology, earthquake physics, and large-scale seismic data analysis to address fundamental questions about fault zone processes.
Appointment: Full-time, 2-year term; salary per UC postdoctoral scale plus benefits.
For consideration, please send a single PDF with cover letter, CV, and three references to amt...@ucdavis.edu. Review of applications will begin May 25th and will continue until the position is filled.
