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 ...

Properties of dynamic earthquake ruptures with heterogeneous stress drop [PDF]
, 2006 Earthquake rupture is a notoriously complex process, at all observable scales. We introduce a simplified semi-dynamic crack model to investigate the connection between the statistical properties of stress and those of macroscopic source parameters such as rupture size, seismic moment, apparent stress drop and radiated energy.

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 ...

Geophysical Research Letters, 2016 The Mw8.4 Illapel earthquake occurred on 16 September was the largest global event in 2015. This earthquake was not unexpected because the hypocenter was located in a seismic gap of the Peru‐Chile subduction zone. However, the source model derived from 3‐

Nonlinear thermoporoelastic effects on dynamic earthquake rupture [PDF]
Journal of Geophysical Research: Solid Earth, 2006 In this study we theoretically examine thermohydraulic effects on dynamic earthquake rupture. We first derive the system of governing equations assuming a thermoporoelastic medium and then conduct numerical calculations based on these equations. Nonlinear feedback between changes in temperature, fluid pressure, and fault slip are shown to play an ...

Part I. Slip Behavior of the San Andreas Fault Through Several Earthquake Cycles Part II. A Structural Interpretation of the Aftershock "Cloud" of the 1992 Mw 7.3 Landers Earthquake [PDF]
, 2003 Part 1 of this thesis addresses the question of how variable fault slip per event is through time. This question is important, because progress in understanding and forecasting large earthquakes depends critically on precise reconstruction of the ...

Analogue earthquakes and seismic cycles: experimental modelling across timescales [PDF]
Solid Earth, 2017 Earth deformation is a multi-scale process ranging from seconds (seismic deformation) to millions of years (tectonic deformation). Bridging short- and long-term deformation and developing seismotectonic models has been a challenge in experimental ...
