Working with Dynamic Earthquake Rupture Models: A Practical Guide

Seismological Research Letters, 2022
AbstractDynamic rupture models are physics-based simulations that couple fracture mechanics to wave propagation and are used to explain specific earthquake observations or to generate a suite of predictions to understand the influence of frictional, geometrical, stress, and material parameters. These simulations can model single earthquakes or multiple

Dynamic rupture of subduction earthquakes located near the trench

Earth and Planetary Science Letters, 2021
Abstract We perform kinematic and dynamic source inversions of four interplate thrust earthquakes that occurred near the trench at the base of the continental wedge in Northern Chile and we compare them to deeper intraplate events. The magnitudes of these interplate events were between Mw 6.3 and Mw 6.5, with hypocentral depths varying between 17.8 ...

Backward earthquake ruptures far ahead of fluid invasion: Insights from dynamic earthquake-sequence simulations

Tectonophysics, 2021
Abstract The 2011 M9 Tohoku-Oki earthquake caused widespread seismicity including that associated with upward fluid migration within the overriding plate. Such fluid-driven earthquake sequences have a peculiar behavior whereby the ruptures of individual small earthquakes propagate in the opposite direction to the direction of pore pressure invasion ...

Earthquake Recurrence and Rupture Dynamics of Himalayan Frontal Thrust, India

Science, 2001
The Black Mango fault is a structural discontinuity that transforms motion between two segments of the active Himalayan Frontal Thrust (HFT) in northwestern India. The Black Mango fault displays evidence of two large surface rupture earthquakes during the past 650 years, subsequent to 1294 A.D.

Dynamic Rupture Simulation Integrated with Earthquake Observations

2014
Dynamic rupture simulations are unique in their contributions to the study of earthquake physics. The current rapid development of dynamic rupture simulations poses several new questions: Do the simulations reflect the real world? Do the simulations have predictive power? Which one should we believe when the simulations disagree?

Modeling dynamic rupture in a 3D earthquake fault model

Bulletin of the Seismological Society of America, 1998
AbstractWe propose a fourth-order staggered-grid finite-difference method to study dynamic faulting in three dimensions. The method uses an implementation of the boundary conditions on the fault that allows the use of general friction models including slip weakening and rate dependence.

Modeling earthquake rupture dynamics across diffuse deforming fault zones

2020
<p>Earthquakes are a multi-scale, multi-physics problem. For the last decades, earthquakes have been modeled as a sudden displacement discontinuity across a simplified (potentially heterogeneous) surface of infinitesimal thickness in the framework of linear elastodynamics.

Pre-P gravity signals from dynamic earthquake rupture: modelling and observations

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
Dynamic earthquake rupture is one of the most extensive and devastating fracture phenomena on the Earth. It causes a sudden crustal deformation around a fault and generates seismic waves that induce bulk density variations propagating with them. Both processes constitute rock-mass redistribution, which is expected to induce simultaneous transient ...

Earthquake rupture dynamics from Graph Neural Networks

Earthquakes arise from tectonic loading of complex fault systems consisting of heterogeneous material parameters, geometry, rheology, and prestress. All of those are subject to uncertainties, and their interactions and sensitivities for the dynamic rupture problem are incompletely understood.
