Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

Natural time analysis of the corrected Mexican seismic catalog using complexity measures
Journal of Physics: ComplexityNatural time analysis (NTA) provides a powerful method to uncover dynamic features hidden behind seismic catalogs and identify when the system enters a critical stage before a major earthquake.

Incorporating Seismic Zonation into Earthquake Catalog Declustering
Abstract Seismic hazard assessment relies upon a complete earthquake catalog, necessitating a declustering procedure to filter out dependent aftershocks or foreshocks from the earthquake catalog. Traditional declustering approaches, such as the Gardner-Knopoff approach, utilize magnitude-dependent temporal and spatial windows to distinguish ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Intermediate‐depth intraslab earthquakes in the Philippine Sea Plate occur at depths of 100–200 km beneath the Ryukyu Arc and are widely interpreted as manifestations of slab dehydration; however, the spatial variability in continuity of the volcanic front and the asymmetric distribution of volcanic activity are poorly explained by existing ...

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Tsunami waveform analyses of the 2006 underthrust and 2007 outer-rise Kurile earthquakes [PDF]
Advances in Geosciences, 2008 The 2006 large interplate Kurile earthquake proved that the entire plate interface of the Kurile-Kamchatka subduction zone was strongly coupled from Hokkaido, Japan, to Kamchatka, Russia.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

Crustal and Upper Mantle Structure Beneath the Corinth Rift Using Receiver Function Analysis
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract The Gulf of Corinth is one of the fastest‐extending continental rifts in Europe, yet the link between present‐day strain, inherited crustal structure, and lithospheric dynamics remains debated. We investigate crustal thickness and Vp/Vs variations using receiver functions from 31 seismic stations.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...
