Surface-Rupturing Historical Earthquakes in Australia and Their Environmental Effects: New Insights from Re-Analyses of Observational Data

Geosciences, 2019
We digitize surface rupture maps and compile observational data from 67 publications on ten of eleven historical, surface-rupturing earthquakes in Australia in order to analyze the prevailing characteristics of surface ruptures and other environmental ...

Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

Tectonic Control of Aseismic Creep and Potential for Induced Seismicity Along the West Valley Fault in Southeastern Metro Manila, Philippines

GeoHazards
Vertical creep along 15 ground ruptures within a 15 km long and 1.5 km wide zone has been occurring along the southeastern part of Metro Manila. Though the unusually high rates of vertical slip point to excessive groundwater withdrawal as the trigger ...

Linked and fully coupled 3D earthquake dynamic rupture and tsunami modeling for the Húsavík–Flatey Fault Zone in North Iceland [PDF]

Solid Earth
Tsunamigenic earthquakes pose considerable risks, both economically and socially, yet earthquake and tsunami hazard assessments are typically conducted separately.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Searching for the effects of the May-June 2012 Emilia seismic sequence (northern Italy): medium-depth deformation structures at the periphery of the epicentral area

Annals of Geophysics, 2012
In 2012, a seismic sequence occurred in the lowlands of the Emilia-Romagna Region (northern Italy), between the borders of the Modena, Ferrara and Bologna Provinces.

FEM‐Peridynamic Modelling of Supershear Earthquake Ruptures in Dry and Fluid‐Saturated Media

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Since ground shaking increases with rupture speed during earthquakes, the velocity transition from sub‐Rayleigh to supershear in mode II fracture is crucial for the propagation of seismic ruptures and associated strong ground motions. We employ a newly conceived 2‐dimensional hybrid Finite Element Method and Peridynamic (FEM/PD‐2D) model to ...

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 ...
