The 2 May 2025 Mw 7.4 Drake Passage Earthquake: Insights Into Tectonics at the Shackleton Fracture Zone–Chilean Trench Transition

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract On 2 May 2025, an Mw 7.4 earthquake occurred ∼120 km off the southern tip of Tierra del Fuego, at the transition of the Shackleton Fracture Zone and the Chile Trench. This event exhibits reverse‐faulting mechanisms with relatively steeply dipping planes and is the largest recorded along this complex plate boundary.

Patch Interactions on a Heterogeneous Fault Drive Nearby Slow and Fast Earthquakes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tectonic tremor and repeating/regular earthquakes off Iwate in the shallow Japan Trench occur episodically and in spatially overlapping areas, implying a common aseismic driver. We investigate how small aseismic slip triggers events across multiple slip‐rate regimes using fully dynamic earthquake‐cycle simulations governed by rate‐and‐state ...

Constraining Fault Kinematics and India‐Tarim Convergence Partitioning in Southwestern Tibet With Geodetic Block Modeling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract How the convergent strain between the India Plate and the Tarim basin is partitioned by active faults and off‐fault deformation in southwestern Tibet is poorly understood due to limited knowledge of strain localisation and fault kinematics. In this study, we derive high‐resolution velocity fields for the southwestern Tibetan Plateau using both

Modulation of Slow Slip Event Characteristics Throughout the Costa Rica Subduction Zone Earthquake Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

Quantifying Deep Ocean Methane Along the Central Chilean Margin

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cold seeps are dynamic seafloor environments that provide conduits for methane (CH4) to be transferred from marine sediments to the global ocean and, in shallow settings, the atmosphere. These seeps are ubiquitous along continental margins yet their spatial extent and impact on the marine carbon cycle are poorly constrained.
