Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

High resolution catalog of the Luxian (Sichuan, China) MS6.0 earthquake sequence and analysis of the seismogenic structuresKey points

Earthquake Science
The epicenter of the Luxian MS6.0 earthquake on September 16, 2021, was located in the southern Sichuan Basin, which is a historically seismically quiescent area.

Evaluating Deep‐Learning‐Based Earthquake Detection in a Sparse Coastal Network: Insights From the 2017 Changdao Swarm, Eastern China

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Constructing reliable earthquake catalogs in regions with sparse station coverage and strong noise remains challenging. We evaluate the performance of a deep‐learning–based detection and location workflow (LOC‐FLOW) using the 2017 Changdao offshore earthquake swarm in eastern China.

Potency–Magnitude Scaling Relations and a Unified Earthquake Catalog for the Western United States

The Seismic Record
Quantifying the size of earthquakes is a foundational task in seismology, and over the years several magnitude scales have been developed. Of these, only scales based on seismic moment or potency can properly characterize changes in event size without ...

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 ...

Anisotropic Permeability Pathways Controlled by Intraslab Stress Heterogeneity in the Philippine Sea Slab Beneath the Ryukyu Arc

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.

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

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.
