Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

Assessing the Yuli surface deformation from the 20220918 Chishang earthquake: an integrated RTK GNSS network approach

Terrestrial, Atmospheric and Oceanic Sciences, 2023
The 20220918 Chishang earthquake impacted the Yuli area in the Longitudinal Valley of eastern Taiwan. Longitudinal Valley is situated near the boundary of the Philippine Plate and Eurasian Plate boundary with frequent seismicity and historical ...

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Bayesian Calibration of Dynamic Models of Earthquake Sequences Using Observations From Past Large Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Physics‐based models of the earthquake cycle could be used for time‐dependent hazard assessment. For such an application, their parameters must be calibrated so that simulated earthquake sequences reproduce the statistics of past earthquakes, including recurrence statistics and magnitudes. This is challenging because the dynamics are described

Poroelastic effects associated with earthquakes on overpressured reverse and normal faults

Frontiers in Earth Science
Earthquakes in fluid-saturated rocks induce sudden changes in pore-pressures that can lead to appreciable postseismic deformation. However, earthquakes can also release fluids from overpressured parts of the crust, which can also contribute to additional

The 1997-1998 Umbria-Marche post-earthquakes investigation: Perspective from a decade of analyses and debates on the surface fractures

Annals of Geophysics, 2008
The Umbria-Marche sequence represents the first case in Italy for which the surface effects of a moderate seismic event (5<M<6) were systematically investigated and documented.

General Solution Scaling Relations in Linear Elastic Dynamic Rupture Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Dynamic rupture models have been widely used to enhance our understanding of earthquake processes and associated hazards. A commonly held insight among modelers is that if the initial stress, rheological parameters, and space and time coordinates are scaled by certain factors in a specific manner, the solution will scale accordingly and remain

Minor shallow gravitational component on the Mt. Vettore surface ruptures related to MW 6, 2016 Amatrice earthquake

Annals of Geophysics, 2016
On 24th August 2016 a ML 6.0 earthquake occurred near Amatrice (central Italy) causing nearly 300 fatalities. The mainshock ruptured a NNW-SSE striking, WSW dipping normal fault.
