High‐Precision Aftershock Distribution Highlights the Complex Fault Geometry of the 2024 Mw 7.5 Noto Peninsula Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We deployed 30 temporary seismic stations around the source region of the 2024 Mw 7.5 Noto Peninsula earthquake to investigate the relationship between mainshock rupture and fault geometry. Using machine learning techniques, we detected and precisely located 46,252 aftershocks, revealing several fault planes corresponding to active faults ...

Frequency‐Dependent Seismic Velocity Variations Reveal Layered Aquifer Behavior Under Groundwater Fluctuations

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.
