On the Application of 1 Versus 2 State Variable Rate‐and‐State Friction Laws: An Example From the Nankai Trough Megasplay Fault Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Frictional slip behavior in fault zones can be analyzed with friction laws using 1 or 2 state variables, but the physical meaning and applicability of the 2‐state variable form of the law remain unclear. Here, we re‐analyze friction experiments by Roesner et al. (2022, https://doi.org/10.1186/s40623‐022‐01728‐w) using a natural sample from the

Permanent Hydraulic and Poroelastic Property Changes in a Deep Aquifer Triggered by the Distant Tohoku Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract While large earthquakes can alter groundwater systems far from the epicenter, their hydromechanical changes remain elusive. We investigate the 2011 Mw 9.0 Tohoku earthquake's impact on a deep well‐aquifer system ∼2,000 km from the epicenter. By employing the groundwater tidal and barometric pressure response methods, we perform tidal response ...

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Characterization of Near‐Surface Velocity Structure at Haast, New Zealand, Using Distributed Acoustic Sensing (DAS) Measurements of Seismicity

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Distributed acoustic Sensing (DAS) data collected along a 30 km length of telecommunications fiber crossing the Alpine Fault near Haast enable analysis of interactions between fluvioglacial and seismotectonic processes. Here we use DAS recordings of 25 earthquakes to probe near‐surface structure beneath the Haast river valley.
