Exploration of Machine Learning Methods to Seismic Event Discrimination in the Pacific Northwest
Akash Kharita, Marine Denolle, Alexander R Hutko +2
Accurately separating tectonic, anthropogenic, and geomorphologic seismic sources is essential for Pacific Northwest (PNW) monitoring but remains difficult as networks densify and…
Agroseismology: unraveling the impact of farming practices on soil hydrodynamics
Qibin Shi, David R. Montgomery, Abigail L. S. Swann +9
Farmed landscapes provide a natural laboratory to test how management reshapes near-surface hydrodynamics. Combining distributed acoustic sensing with physics-based hydromechanical…
A Review of Cloud Computing in Seismology
Yiyu Ni, Marine A. Denolle, Jannes Munchmeyer +7
Seismology has entered the petabyte era, driven by decades of continuous recordings of broadband networks, the increase in nodal seismic experiments, and the recent emergence of Di…
A Global-scale Database of Seismic Phases from Cloud-based Picking at Petabyte Scale
Yiyu Ni, Marine A. Denolle, Amanda M. Thomas +6
We present the first global-scale database of 4.3 billion P- and S-wave picks extracted from 1.3 PB continuous seismic data via a cloud-native workflow. Using cloud computing servi…
Active Protothrusts and Fluid Highways: Seismic Noise Reveals Hidden Subduction Dynamics in Cascadia
Maleen Kidiwela, Marine A. Denolle, William S. D. Wilcock +1
Complex interactions between strain accumulation, fault slip, and fluid migration influence shallow subduction zone dynamics. Using a decade of continuous ambient seismic data from…
