Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

Large Earthquakes Along the Mendocino Oceanic Transform Fault Hardly Have Any Foreshocks

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Compared to continental strike‐slip faults, oceanic transform faults (OTFs) are thought to mainly slip aseismically and host significantly more foreshocks triggered by precursory aseismic slip which enhance the mainshocks' short‐term predictability. However, long‐term high‐resolution observational constraints remain limited.

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.

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.

Coseismic Displacements from Moderate-Size Earthquakes Mapped by Sentinel-1 Differential Interferometry: The Case of February 2017 Gulpinar Earthquake Sequence (Biga Peninsula, Turkey)

Remote Sensing, 2018
We study the tectonic deformation from the February 2017 shallow earthquake sequence onshore Biga Peninsula (NW Turkey, NE Aegean region). We use InSAR interferograms (Sentinel-1 satellites) to identify the seismic fault (striking N110°E) and ...

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

Prolonged Hypocenter Migration in a Lower‐Crustal Earthquake Swarm in Japan: Positive Feedback Between Heat Influx and Fluid Production

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Yamaguchi earthquake swarm in western Japan occurred at unusually deep depths (25–40 km), well below the seismogenic zone, and exhibited prolonged zigzag hypocenter migrations over at least ∼180 days. Seismicity initiated in the southwestern part of the swarm area, followed by systematic migration eastward, northeastward, and northwestward.

Hypocenter relocation of the aftershocks of the Mw 7.5 Palu earthquake (September 28, 2018) and swarm earthquakes of Mamasa, Sulawesi, Indonesia, using the BMKG network data

Geoscience Letters, 2019
On September 28, 2018, the Mw 7.5 earthquake occurred in Palu, Central Sulawesi, Indonesia. This earthquake produced strong tremors, landslides, liquefaction and a tsunami and caused thousands of fatalities and damaged houses and infrastructure.

Fine‐Scale Segmentation and Spatiotemporal Variability of the 2010 Mw 8.8 Maule Aftershock Sequence Revealed by a Deep‐Learning‐Based Earthquake Catalog

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We re‐examine the aftershock sequence of the Mw 8.8 Maule earthquake in south‐central Chile to understand how seismicity, magnitude‐frequency distribution, and fault structure vary along the rupture zone. Using the International Maule Aftershock Deployment (IMAD) data set, we analyze 10 months of continuous data from approximately 156 ...

Machine-learning based earthquake detection and location around the Tanlu fault zone in eastern China

Geophysical Journal International
The Tanlu fault zone is an NNE-SSW oriented, large and deep strike-slip fault system running through eastern China. To investigate seismotectonics in and around the Tanlu fault zone, we adopt the LOC-FLOW approach to build a high-precision earthquake ...
