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

Geophysical 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.

Utilizing distributed acoustic sensing and ocean bottom fiber optic cables for submarine structural characterization

Scientific Reports, 2021
The sparsity of permanent seismic instrumentation in marine environments often limits the availability of subsea information on geohazards, including active fault systems, in both time and space. One sensing resource that provides observational access to

A Propaedeutic Dataset to Investigate the Submarine Landslide Area Offshore the Apulian Foreland (Eastern Taranto Gulf, Ionian Sea, Southern Italy)

Geoscience Data Journal, Volume 13, Issue 1, January 2026.
The main goal is the building of a dataset from vintage seismic reflection profiles, processed and improved (SEG‐Y files), for future investigation of a major submarine landslide area on the Taranto Trench outer slope. To complete the dataset, the digitalisation of a representative sonic log was performed (CSV file). ABSTRACT The outer Apulian Foreland

Rupture Directivity From Energy Envelope Deconvolution: Theory and Application to 58 Ridgecrest M 3.5–5.5 Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Earthquake rupture directivity impacts ground motions and provides insights on fault zone properties and earthquake physics. However, measuring directivity of small earthquakes is challenging due to their compact rupture sizes and complex path and site effects at high frequencies.

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

Evidence of Subduction, Collision, and Extension in Northern Borneo: Constraints From Receiver Functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract What happens when subduction stops is a key, but poorly understood, part of the tectonic cycle. Northern Borneo (Sabah) with a complex geological history of multiple episodes of subduction, magmatism, uplift, subsidence, and extension since the Mesozoic, is an ideal location for studying post‐subduction processes.

Imaging of Magma Intrusion Below La Palma During a Strong Effusive Eruption in 2021 Inferred From Repeated Seismic Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...

Spatio-temporal changes in the seismic velocity induced by the 2011 Tohoku-Oki earthquake and slow slip event revealed from seismic interferometry, using ocean bottom seismometer’s records

Progress in Earth and Planetary Science, 2018
Seismic interferometry is one of the most effective techniques for detecting temporal variations in seismic velocity caused by large earthquakes. Before the 2011 Tohoku-Oki earthquake (M w 9.0) near the Japan Trench, a slow slip event (SSE, M w 7.0) and ...
