The physics of earthquakes [PDF]

, 2004
Earthquakes occur as a result of global plate motion. However, this simple picture is far from complete. Some plate boundaries glide past each other smoothly, while others are punctuated by catastrophic failures.

Contrasting Decollement and Prism Properties over the Sumatra 2004-2005 Earthquake Rupture Boundary [PDF]

, 2010
Styles of subduction zone deformation and earthquake rupture dynamics are strongly linked, jointly influencing hazard potential. Seismic reflection profiles across the trench west of Sumatra, Indonesia, show differences across the boundary between the ...

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...

Dynamic Rupture Modelling of the 1999 Düzce, Turkey Earthquake

Pure and Applied Geophysics, 2017
The dynamic rupture process and near-source ground motion of the 1999 Mw 7.1 Du¨zce Earthquake are simulated. The fault rupture is governed by the slip-weakening friction model coupled to a three-dimensional viscoelastic wave equation. The problem is solved numerically by a 3-D dynamic rupture code that uses a generalized finite difference method ...

Verification of an ADER-DG method for complex dynamic rupture problems [PDF]

Geoscientific Model Development, 2014
We present results of thorough benchmarking of an arbitrary high-order derivative discontinuous Galerkin (ADER-DG) method on unstructured meshes for advanced earthquake dynamic rupture problems.

Earthquake rupture dynamics: Comparing the numerical simulation methods [PDF]

Eos, Transactions American Geophysical Union, 2004
Thirty years ago, scientists first developed computer programs that could tackle the complicated problem of simulating earthquakes as dynamic rupture processes, and predicting the ensuing fault movement.At first, only a few people were able to formulate the appropriate numerical solutions, but these researchers were working with methods that could ...

How does dissipation affect the transition from static to dynamic macroscopic friction? [PDF]

, 2014
Description of the transitional process from a static to a dynamic frictional regime is a fundamental problem of modern physics. Previously we developed a model based on the well-known Frenkel-Kontorova model to describe dry macroscopic friction.

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]

, 2011
We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.

Stochastic Dynamics for Earthquake Ruptures

, 2018
In this paper, we propose a stochastic dynamic model for earthquake rupture and suggest that the Langevin equation of frictions may be used for interpreting the slip distributions of rupture processes in earthquakes. The steady-state solution of the derived Langevin equation analytically attains the truncated exponential (TEX) distribution that is ...
