An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Earthquake rupture velocity and stress drop interaction in the Campi Flegrei volcanic caldera

Communications Earth & Environment
During an earthquake rupture, both dynamic and static stress drop play a key role in controlling how much energy is radiated as seismic waves, how large is the fault slip, and how quickly the rupture spreads out of the nucleation zone.

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Characteristics of Seismic Energy Rate Functions of Shallow Tremors

Geophysical Research Letters
We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Infrasound Unmasks Flow Turbulence as an Additional Seismic Source in Debris Flows

Geophysical Research Letters
Debris flows radiate both seismic and infrasonic waves. According to previous studies, seismic energy is generated by the solid particle collisions with the riverbed and is dominated by the boulder‐rich front, while infrasound is produced by turbulence ...

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...
