Contemporary crustal stress of the Greek region deduced from earthquake focal mechanisms

V Kapetanidis, I Kassaras - Journal of Geodynamics, 2019 - Elsevier
A massive dataset of over 1900 focal mechanisms of crustal earthquakes with M≥ 3.5 in the
Greek region was employed to resolve the contemporary stress-field using a damped least …

Outer trench slope flexure and faulting at Pacific basin subduction zones

ESM Garcia, DT Sandwell… - Geophysical Journal …, 2019 - academic.oup.com
Flexure and fracturing of the seafloor on the outer trench wall of subduction zones reflect
bending of the lithosphere beyond its elastic limit. To investigate these inelastic processes …

Gravitational body forces focus North American intraplate earthquakes

W Levandowski, M Zellman, R Briggs - Nature Communications, 2017 - nature.com
Earthquakes far from tectonic plate boundaries generally exploit ancient faults, but not all
intraplate faults are equally active. The North American Great Plains exemplify such …

Dense lower crust elevates long‐term earthquake rates in the New Madrid seismic zone

W Levandowski, OS Boyd… - Geophysical Research …, 2016 - Wiley Online Library
Abstract Knowledge of the local state of stress is critical in appraising intraplate seismic
hazard. Inverting earthquake moment tensors, we demonstrate that principal stress …

An iterative spectral solution method for thin elastic plate flexure with variable rigidity

ES Garcia, DT Sandwell… - Geophysical Journal …, 2015 - academic.oup.com
Thin plate flexure theory provides an accurate model for the response of the lithosphere to
vertical loads on horizontal length scales ranging from tens to hundreds of kilometres …

The rigid‐plate and shrinking‐plate hypotheses: Implications for the azimuths of transform faults

JK Mishra, RG Gordon - Tectonics, 2016 - Wiley Online Library
The rigid‐plate hypothesis implies that oceanic lithosphere does not contract horizontally as
it cools (hereinafter “rigid plate”). An alternative hypothesis, that vertically averaged …

Absolute stress fields in the source region of the 1992 Landers earthquake

T Terakawa, E Hauksson - Journal of Geophysical Research …, 2018 - Wiley Online Library
Earthquake focal mechanisms are often inverted to obtain the deviatoric stress field.
Because shear stress is equal to the frictional strength of the fault at the time of an …

Limits on crustal differential stress in southern California from topography and earthquake focal mechanisms

K Luttrell, B Smith-Konter - Geophysical Journal International, 2017 - academic.oup.com
The in situ crustal stress field fundamentally governs, and is affected by, the active tectonic
processes of plate boundary regions, yet questions remain about the characteristics of this …

Crustal stress state in Taiwan: Moderately strong crust supporting gravitational and flexural loading

YR Yang, KM Johnson - Journal of Geophysical Research …, 2020 - Wiley Online Library
In Taiwan and other contractional tectonic wedges, there is evidence that the basal
detachment is very weak and the overlying crust is relatively strong. In this study, we …

Kinematic boundary conditions favouring subduction initiation at passive margins over subduction at mid-oceanic ridges

A Auzemery, E Willingshofer, P Yamato… - Frontiers in Earth …, 2021 - frontiersin.org
We perform numerical modelling to simulate the shortening of an oceanic basin and the
adjacent continental margins in order to discuss the relationship between compressional …
