Surface ruptures and building damage of the 2003 Bam, Iran earthquake mapped by satellite synthetic apeerture radar interferometric correlation [PDF]

We use the interferometric correlation from Envisat synthetic aperture radar (SAR) images to map the details of the surface ruptures related to the 26 December 2003 earthquake that devastated Bam, Iran.

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Earthquake rupture extents and coseismic slips promoted by damaged fault zones [PDF]

Journal of Geophysical Research: Solid Earth, 2016
AbstractHere we investigate the effects of damage fault zones on rupture propagation by conducting a series of 3‐D dynamic rupture simulations on a planar vertical strike‐slip fault. We find that damage fault zones can promote rupture extent and increase earthquake potency.

Strain localization driven by thermal decomposition during seismic shear [PDF]

, 2015
Field and laboratory observations show that shear deformation is often extremely localized at seismic slip rates, with a typical deforming zone width on the order of a few tens of microns. This extreme localization can be understood in terms of thermally

Deformation Patterns and Rupture Mechanisms of the Longitudinal Valley Fault in Eastern Taiwan: Insights From Three‐Dimensional Discrete Element Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Active faults exhibit complex geometric features, with rupture processes controlled by the coupled effects of tectonic loading, fault geometry, and internal displacement heterogeneity. To elucidate the interrelationship between long‐term deformation, stress redistribution, and rupture evolution, we constructed a three‐dimensional numerical ...

Stima della potenza dissipata per attrito durante i terremoti: confronto tra faglie sperimentali e naturali. = Estimate of frictional seismic power dissipation from natural and experimental faults. [PDF]

, 2012
In the last decades, several approaches were applied to understand the physics of seismic faulting. In the field, the recognition of pseudotachylytes (solidified friction melts produced during seismic slip) which record seismic ruptures along a fault ...

Slip distribution of the February 6, 2023 Mw 7.8 and Mw 7.6, Kahramanmaraş, Turkey earthquake sequence in the East Anatolian Fault Zone

Seismica, 2023
On February 6, 2023, two large earthquakes occurred near the Turkish town of Kahramanmaraş. The moment magnitude (Mw) 7.8 mainshock ruptured a 310 km-long segment of the left-lateral East Anatolian Fault, propagating through multiple releasing step ...

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

GPS observations of coseismic deformation following the 2016, August 24, Mw 6 Amatrice earthquake (central Italy): data, analysis and preliminary fault model

Annals of Geophysics, 2016
We used continuous Global Positioning System (GPS) measurements to infer the fault geometry and the amount of coseismic slip associated to the August 24, 2016 Mw 6 Amatrice earthquake.

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...
