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

Tectono‐Stratigraphic Evolution of a Shared Foreland Basin: A 3D Geomodel and Detrital Flux Reconstruction for the Pliocene‐Pleistocene of the Po‐Plain Basin (Northern Italy)

Basin Research, Volume 38, Issue 5, September‐October 2026.
The Plio‐Pleistocene succession of the Po Plain Basin was interpreted basin‐wide using seismic profiles and well data, identifying six major tectonic unconformities. Sediment volumes were calculated and decompacted to assess tectonic and climatic controls on basin infill, revealing a marked increase in detrital flux after 1.5 Ma, coincident with the ...

Detailed Shallow Shear Velocity Structure in the Nankai Trough From Ambient Noise Differential Adjoint Tomography: Implications for Earthquake Generation Mechanisms

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Seismic and aseismic slip has been reported in the Nankai Trough. In this study we apply ambient noise differential adjoint tomography to obtain a high‐resolution S‐wave velocity (Vs) model in the Nankai Trough. The Vs in the very shallow imbricate thrust zone is higher than that on both the seaward and landward sides.

MORB-derived amphibolites in the Paleozoic basement of the Aluminé Igneous-Metamorphic Complex, Neuquén, Argentina: Decoding its genesis, P-T evolution and pre-Andean regional correlations

Geologica Acta, 2019
Amphibolites included in the metapelitic sequence and as xenoliths in intrusive magmatic rocks outcropping in the southern sector of the Aluminé Igneous-Metamorphic Complex (AIMC), Neuquén, Argentina, are studied in detail in order to determine their ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

BACTERIAL COLONIES AND MANGANESE MICRONODULES RELATED TO FLUID ESCAPE ON THE CREST OF THE MEDITERRANEAN RIDGE

Rivista Italiana di Paleontologia e Stratigrafia, 2018
A black, few centimeters thick Marker-bed of Holocene age is consistently recorded in all the deep-sea cores raised from two fields of mud diapirs recently discovered on the crest of the Mediterranean Ridge south of Crete.

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

Out‐of‐sequence thrusting in experimental Coulomb wedges: Implications for the structural development of mega‐splay faults and forearc basins

Geophysical Research Letters, 2012
We have investigated how an arc‐ward increase in bulk mechanical strength in an experimental accretionary prism influences the development, timing, and duration of slip on out‐of‐sequence thrusts.
