A seismic quantitative identification method of slope break belt

Petroleum Exploration and Development, 2016
Based on the slope variation characteristics of slope break belt and slope theory in geomorphology, a method, which can quantitatively identify the slope break belt based on the precise seismic horizon data and slope gradient and aspect attribute, was ...

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Definition of seismic and tsunami hazard scenarios by exploiting EU-India Grid e-infrastructures [PDF]

, 2012
Seismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude.

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.

High-resolution mapping based on an Unmanned Aerial Vehicle (UAV) to capture paleoseismic offsets along the Altyn-Tagh fault, China

Scientific Reports, 2017
The recent dramatic increase in millimeter- to centimeter- resolution topographic datasets obtained via multi-view photogrammetry raises the possibility of mapping detailed offset geomorphology and constraining the spatial characteristics of active ...

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

Application of 9-component S-wave 3D seismic data to study sedimentary facies and reservoirs in a biogas-bearing area: A case study on the Pleistocene Qigequan Formation in Taidong area, Sanhu Depression, Qaidam Basin, NW China

Petroleum Exploration and Development
To solve the problems in restoring sedimentary facies and predicting reservoirs in loose gas-bearing sediment, based on seismic sedimentologic analysis of the first 9-component S-wave 3D seismic dataset of China, a fourth-order isochronous stratigraphic ...

The Parguera Fault System: Possible Quaternary Reactivation of Bedrock Faults in Southwest Puerto Rico

Tectonics, Volume 45, Issue 9, September 2026.
Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.

LiDAR and GPR Data Reveal the Holocene Evolution of a Strandplain in a Tectonically Active Coast

Remote Sensing
This study investigates the Holocene evolution of the Laraquete-Carampangue strandplain on the tectonically active coast of south-central Chile using ground penetrating radar and light detection and ranging data. The Laraquete-Carampangue strandplain, on

Learning From Crushing Failures: Changes in Physical Properties Reveal the Mechanics of Submarine Carbonate Landslides

Basin Research, Volume 38, Issue 5, September‐October 2026.
Changes in the physical properties of calcareous ooze between intact weak layers and glide planes within the same stratigraphy provide new constraints on the deformation processes and mechanical factors that control the mobility and erosive behaviour of submarine carbonate landslides.
