Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

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

open access: yesJournal 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.

Holocene Slip Behavior and Shallow Structure of the Milun Fault at the Collision–Subduction Transition, Eastern Taiwan

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Milun Fault forms the northernmost onshore segment of the Longitudinal Valley fault system, a plate‐boundary suture between the Eurasian and Philippine Sea plates in eastern Taiwan, and poses a significant seismic hazard to Hualien City. Despite destructive earthquakes in 1951 and 2018, the shallow structure, long‐term slip behavior, and ...

Hydrological Impact of Earthquakes on Reverse and Normal Faults: Results From Numerical Models

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract I investigate earthquake‐induced hydrological signals related to poroelastic deformation, thermal pressurization, fault‐zone dilatancy and rupture of a pressurized reservoir at depth. This is performed using a two dimensional plane strain model that simulates ruptures on reverse and normal faults governed by rate‐and‐state friction coupled to ...

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Facies analysis provides new insights into event bed deposition in a hadal trench environment

open access: yesSedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...
