A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Growth Rate and Energy Dissipation in Wind‐Forced Breaking Waves

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We investigate the energy growth and dissipation of wind‐forced breaking waves at high wind speed using direct numerical simulations of the coupled air–water Navier–Stokes equations. A turbulent wind boundary layer drives the growth of a pre‐existing narrowband wave field until it breaks, transferring energy into the water column.

Implications for Oceanographic and Seafloor Geodetic Applications Due To Settling of Self‐Calibrating Bottom Pressure Recorders

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ocean bottom pressure recordings are a key observation for both ocean circulation and seafloor geodesy. New self‐calibrating instruments may solve a long‐time issue of instrument drift, allowing new high precision observations. However, instruments on the seafloor may settle over days to months, potentially contaminating results.

Rupture Dynamics of the 2025 Mw 7.7 Myanmar Earthquake: A Bilateral Supershear Rupture on Unusually Long Fault Superhighway

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The 2025 Mw 7.7 Myanmar earthquake ruptured the central Sagaing fault, a previously identified seismic gap with high seismic potential. Here, we perform hundreds of 3D dynamic rupture simulations to investigate the rupture dynamics, constrained by near‐fault strong‐motion waveforms, optical and SAR pixel offsets, and a kinematic source model ...

Revealing Blind Faults Through High‐Resolution Imaging of Shallow Structures: A Case Study on Chenghai Fault, Yunnan, China

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Blind faults pose significant seismic hazards because they remain hidden beneath the surface and are often unrecognized until they generate large earthquakes. High‐resolution shallow velocity models are essential for imaging these blind structures.
