Dynamic Rupture Modeling with a Rate and State Friction Law in a Discontinuous Galerkin Method

Geofísica Internacional
Earthquake rupture modeling has proven to be a useful tool to understand the physics behind different slip sequences inferred from observations. However, modeling the earthquakes dynamics is challenging due to the complex frictional behavior during the ...

How the Transition Region Along the Cascadia Megathrust Influences Coseismic Behavior: Insights From 2‐D Dynamic Rupture Simulations

Geophysical Research Letters, 2019
There is a strong need to model potential rupture behaviors for the next Cascadia megathrust earthquake. However, there exists significant uncertainty regarding the extent of downdip rupture and rupture speed.

2022年青海门源MW6.6地震震源动力学破裂过程

Dizhen xuebao
2022年1月8日青海门源MW6.6地震在地表产生了较强的破坏，为研究门源地震产生强地表破裂及阻碍托莱山东段应力释放的构造背景，本文采用谱元法模拟了门源地震曲面分支断层在实际地形下的动力学破裂过程。结果显示，破裂自初始破裂点沿断层上倾方向同时发生双侧破裂；受震源区上方高速P波异常体的影响，断层产生非连续破裂。在破裂传播到托莱山东段时，断层的滑动速度和滑动量发生明显的阶跃式下降；此外，近地表处滑动速率约3.6 m/s的区域可能为强地面运动生成区 ...

Quantifying the Influence of Fault Geometry via Mesh Morphing With Applications to Earthquake Dynamic Rupture and Thermal Models of Subduction

Geochemistry, Geophysics, Geosystems
Subsurface geometries, such as faults and subducting slab interfaces, are often poorly constrained, yet they exert first‐order control on key geophysical processes, including subduction zone thermal structure and earthquake rupture dynamics.

Dynamic Rupture Simulation Reproduces Spontaneous Multifault Rupture and Arrest During the 2016 Mw 7.9 Kaikoura Earthquake

Geophysical Research Letters, 2018
The 2016 Kaikoura (New Zealand) earthquake is characterized as one of the most complex multifault rupture events ever observed. We perform dynamic rupture simulations to evaluate to what extent relatively simple forward models accounting for realistic ...

3D Dynamic Rupture Modeling of the 6 February 2023, Kahramanmaraş, Turkey Mw 7.8 and 7.7 Earthquake Doublet Using Early Observations

The Seismic Record, 2023
The 2023 Turkey earthquake sequence involved unexpected ruptures across numerous fault segments. We present 3D dynamic rupture simulations to illuminate the complex dynamics of the earthquake doublet.

Dynamic Simulation of Seismogenic-Fault-Induced Rupture in Overlying Soil

Infrastructures
Accurate prediction of surface rupture induced by seismogenic fault displacement is essential for the seismic safety assessment of major engineering projects. Most existing numerical simulations adopt quasi-static approaches, in which the effect of fault

Dynamic Rupture Process of the 2023 Mw 7.8 Kahramanmaraş Earthquake (SE Türkiye): Variable Rupture Speed and Implications for Seismic Hazard

Geophysical Research Letters, 2023
We considered various non‐uniformities such as branch faults, rotation of stress field directions, and changes in tectonic environments to simulate the dynamic rupture process of the 6 February 2023 Mw 7.8 Kahramanmaraş earthquake in SE Türkiye.

Partial ruptures governed by the complex interplay between geodetic slip deficit, rigidity, and pore fluid pressure in 3D Cascadia dynamic rupture simulations

Seismica
Physics-based dynamic rupture simulations are valuable for assessing the seismic hazard in the Cascadia subduction zone (CSZ), but require assumptions about fault stress and material properties.
