The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, Volume 41, Issue 5, Page 732-753, July 2026.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Geomorphological Evidence of Active Faulting on Alluvial Fan Along Northeastern Margin of Tibetan Plateau (NW China)

Remote Sensing
Complete records of fault activity are very valuable for assessing possible earthquakes. Fault scarps are one key to exploring past fault activity. Through the records of fault scarps, we can obtain evidence of fault activity and faulting events in ...

Investigation on Reflection of Tectonic Pattern in ASG EUPOS Data in the Sudetes and Adjacent Areas

Reports on Geodesy and Geoinformatics, 2016
The GNSS data evaluated from on observation of ASG EUPOS stations in the Sudety Mts. and in adjacent areas is analyzed by the author in the scope of disturbances in daily solutions that can be induced by tectonics stress.

The CRESCENT Generation 0 Cascadia Community Velocity Model: Constraints From the Joint Inversion of Teleseismic Receiver Functions and Ambient Noise Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Cascadia subduction zone can produce M9+ megathrust and M6.5+ intraplate earthquakes, motivating the need for a detailed 3‐D model of seismic properties at scales relevant to regional geology, basins, and infrastructure. To construct the Generation 0 Cascadia Region Earthquake Science Center Community Velocity Model (CRESCENT CVM), we ...

Some features of deformation structures in an esker on the southern margin of the Fennoscandian shield [PDF]

Bulletin of the Geological Society of Finland, 2018
As a result of melting of the last ice sheet in the southeastern edge of the Fennoscandian shield, ridge structures called eskers were formed. One of these eskers is the subject of our study.

Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 1. Upper Plate Structures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We represent the active deformation of the Aegean region with an elastic‐kinematic block model composed of a finite number of rotating crustal blocks whose boundaries coincide with major active structures. A total of 832 GPS velocities and 146 earthquake slip vectors were inverted to provide estimates of block rotations and interseismic ...

Geomorphic changes after the 2021 Central European flood in the Ahr Valley by LiDAR-based differences

Environmental Sciences Europe
Background In July 2021, destructive floods in Western Europe were triggered by enormous precipitation rates related to a low-pressure system named "Bernd." These catastrophic events led not only to major damage to infrastructure, severe economic losses,

Tectonic Deformation Analysis with ALOS-Based Digital Elevation Models in the Longshou Shan Mountains (NW China)

GeoHazards
The Longshou Shan area is located on the northeastern margin of the Tibetan Plateau in northwest China. The study area is located where the sinistral Altyn Tagh and Haiyuan Faults overlap and the Qilian Shan thrust fault systems in the northeastern ...

Influence of neotectonics on land surface evolution in the upper part of the Blue Nile Basin (Ethiopia): findings from a DEM

Acta Universitatis Carolinae Geographica, 2019
The morphometric analysis of lineaments, valleys and signs of erosion taken from a digital elevation model (DEM) made it possible to not only confirm most of the conclusions of the morphotectonic development of the Blue Nile Basin from the previously ...

New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.
