The paper investigates strike-slip fault rupture propagation through dense sand and its interaction with surface foundations, employing 3D finite element (FE) modelling. Two soil constitutive models (implemented in Abaqus user subroutines) are employed for this purpose: (i) a recently developed simple yet efficient model Mohr–Coulomb yield criterion, which incorporates post-yield isotropic fric...

The October, 1995 Mw 8.0 Jalisco subduction earthquake has provided a thorough geodetic observation of the coseismic subduction process. An 11 station regional GPS network located directly onshore of the rupture demonstrates consistent vertical subsidence verified by tide gauge data and southwest-directed extension, with measured displacements reaching I meter. Unusually shallow and non-uniform...

[1] To investigate the possible physical mechanisms of recently observed aseismic slip events in the Cascadia, Japan and Mexico subduction zones, we apply a Dieterich-Ruina rate and state friction law to a three dimensional model of a shallow subduction fault. That is loaded by imposed steady plate slip rate far downdip along the thrust interface. Friction properties are temperature and hence d...

The Bay St. George sub-basin of SW Newfoundland, part the larger late Paleozoic Maritimes basin, formed under influence strike-slip faulting and movement evaporites. New stratigraphic correlations between Newfoundland other sub-basins illustrate effects both basement salt movement. Coastal outcrops show complex combinations synsedimentary, salt-related, tectonic structures. Map relationships dr...

Abstract. Transpressional uplift domains of inverted Pliocene–Pleistocene basin fill along the San Andreas fault zone in Coachella Valley, southern California (USA), are characterized by linkage and segmentation deformation partitioning. The Indio Hills wedge-shaped block is located between two boundary strands, to northeast main southwest, which merge southeast. Uplift commenced about or later...

We ​study the spatial variability of crustal stress in northern Chile. A margin-parallel compressive regime is inferred along coastal region between 19° and 23.5°S, similar to observations Cascadia Japan. The Andean Precordillera shows a distinct field associated with strike-slip faulting around 21°S. These results are constrained by over decade observations, for which earthquake catalogs repor...
