Depth Dependence of Coseismic Off‐Fault Damage and Its Effects on Rupture Dynamics

Journal of Geophysical Research: Solid Earth
Abstract Faults are complex systems embedded in an evolving medium fractured by seismic ruptures. This off‐fault damage zone is shown to be thermo‐hydro‐mechano‐chemically coupled to the main fault plane by a growing number of studies. Yet, off‐fault medium is still, for the most part, modeled as a purely elastic—hence passive—medium.

The 21 August 2017 Md 4.0 Casamicciola Earthquake: First Evidence of Coseismic Normal Surface Faulting at the Ischia Volcanic Island [PDF]

, 2018
On 21 August 2017, a shallow earthquake of Md 4.0 struck the CasamicciolaTerme village in the north of Ischia volcanic island (Italy). It caused two fatalities and heavy damage in a restricted area of a few square kilometers.

From regional to local SPTHA: efficient computation of probabilistic tsunami inundation maps addressing near-field sources [PDF]

Natural Hazards and Earth System Sciences, 2019
Site-specific seismic probabilistic tsunami hazard analysis (SPTHA) is a computationally demanding task, as it requires, in principle, a huge number of high-resolution numerical simulations for producing probabilistic inundation maps.

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.

Estimating Off‐Fault Deformation Using Convolutional Neural Networks Trained on Experimental Strike‐Slip Faults

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Scaled physical experiments using crustal analog materials can simulate off‐fault deformation near strike‐slip faults and provide direct observations of deformation partitioning during strike‐slip fault evolution. Using experimental fault maps and off‐fault deformation labels, we trained and tested four 2D Convolutional Neural Networks (CNNs ...

COSEISMIC STRATIGRAPHY: A USEFUL APPROACH IN THE STUDY OF ACTIVE TECTONIC BASIN SCENARIOS IN CENTRAL MEXICO [PDF]

, 2016
We propose the concept of coseismic stratigraphy, an approach that could be highly useful for studying lacustrine basins in zones with important tectonic activity. Extant and past lakes have been studied in many parts of the world with paleolimnological

Temporal change in seismic velocity associated with an offshore M W 5.9 Off-Mie earthquake in the Nankai subduction zone from ambient noise cross-correlation

Progress in Earth and Planetary Science, 2018
The Nankai subduction zone off the Kii Peninsula, Japan, has a large potential to generate megathrust earthquakes in the near future. To investigate the temporal variation of stress or strain in the Nankai subduction zone, we estimated the temporal ...

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: 2. Hellenic Subduction System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Hellenic subduction system is the primary locus of Nubia‐Eurasia convergence, yet the distribution of strain accumulation along it is still debated. Here, we invert 832 geodetic velocities and 146 earthquake slip vectors to assess the spatial variability of interseismic locking and provide new constraints on the rate of slip deficit ...

Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...
