Seismogenic zonation and seismic hazard estimates in a Southern Italy area (Northern Apulia) characterised by moderate seismicity rates [PDF]

Natural Hazards and Earth System Sciences, 2009
The northernmost part of Apulia, in Southern Italy, is an emerged portion of the Adriatic plate, which in past centuries was hit by at least three disastrous earthquakes and at present is occasionally affected by seismic events of moderate energy. In the

Embrittlement Within Viscous Shear Zones Across the Base of the Subduction Thrust Seismogenic Zone

Geochemistry, Geophysics, Geosystems, 2022
Geophysical observations indicate that patches of localized fracturing occur within otherwise viscous regions of subduction plate boundaries. These observations place uncertainty on the possible down‐dip extent of the seismogenic zone, and as a result ...

The 2021–2022 Fukushima‐Oki Earthquakes in Northeastern Japan: Dehydration Triggered Fault Reactivation Boosted by Slab Segmentation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The 2021–2022 Fukushima‐Oki earthquakes in northeastern Japan provide a valuable opportunity to deepen our understanding of intraslab earthquakes generated by the reactivation of subducted outer‐rise bending faults. This study integrates high‐resolution seismic velocity models with numerical modeling results to investigate the roles of slab ...

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

The Role of Crustal Rheology and Mantle Fluids on the Interseismic Behavior of the Main Marmara Fault

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Faults can release tectonic loading either in the form of seismic events or via aseismic creep. The Main Marmara Fault (MMF) in the Sea of Marmara exhibits both locked and creeping behavior and poses a significant hazard to the megacity of Istanbul.

Evaluating Coseismic Landslide Susceptibility Following the 2022 Luding Earthquake: A Comparative Analysis of Six Displacement Regression Models Integrating Epicentral and Seismogenic Fault Distances within the Permanent-Displacement Framework

Remote Sensing
Coseismic landslides have the potential to cause catastrophic disasters. Thus, it is of crucial importance to conduct a comprehensive regional assessment of susceptibility to coseismic landslides.

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

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 ...

Investigation of Coulomb stress changes in south Tibet (central Himalayas) due to the 25th April 2015 M W 7.8 Nepal earthquake using a Coulomb stress transfer model

Earthquake Science, 2016
After M W 7.8 Nepal earthquake occurred, the rearrangement of stresses in the crust commonly leads to subsequent damaging earthquakes. We present the calculations of the coseismic stress changes that resulted from the 25th April event using models of ...
