Sentinel‐1 SAR Estimates of Snowmelt Onset Coincide With SNOTEL Soil Moisture Pulses Across the Western United States

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study integrates repeated in situ measurements, data from 260 SNOw TELemetry (SNOTEL) stations, and paired Sentinel‐1 SAR observations across the Western United States to assess snowpack evolution prior to and after Sentinel‐1 SAR‐derived snowmelt runoff onset.

Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions. However, these processes do not always produce surface manifestations and may sometimes elude detection by current geological and geodetic monitoring.

Self‐Supervised Learning Based Clustering Workflow for Exploring Seismological Data From Dense Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract A key challenge in environmental seismology is processing seismic data to study source physics, natural and human‐induced forcings, and geological structures such as landslides, glaciers, and volcanoes. Seismic arrays with dozens of stations have expanded data set sizes, and this, combined with signal complexity and high noise levels, makes it

Slab Tearing and Break‐Off Revealed by the 2024 M7.4 Taiwan Earthquake

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Subduction zone earthquakes typically occur along plate interfaces or within subducting slabs, but rupture mechanisms at mixed collision–subduction boundaries remain poorly understood. The 2024 Mw 7.4 Hualien earthquake struck the suture between the Philippine Sea Plate and the Eurasian Plate in eastern Taiwan.
