Cascade and pre-slip models oversimplify the complexity of earthquake …
2024年3月11日 · Our analysis reveals common patterns, and sheds light on the interplay of structural, tectonic and other boundary conditions that influence the dynamics of earthquake …
Two end-member earthquake preparations illuminated by ... - Nature
2021年7月14日 · By tuning fault surface heterogeneity, the authors report earthquake preparation processes respectively driven by preslip and cascade-up on a meter-scale laboratory fault.
Competition between preslip and deviatoric stress modulates …
2021年1月1日 · We document precursory changes in elastic wave properties for lab earthquakes. Elastic wave speed is sensitive to changes in wallrock stress state. Fault zone elastic …
Physical Mechanisms of Earthquake Nucleation and Foreshocks: …
2024年11月16日 · The preslip model (Fig. 2 a) asserts that precursory aseismic slip occurs during earthquake nucleation, which can drive both foreshocks as well as the initial rupture of the …
Earthquake Nucleation and Slip Behavior Altered by Stochastic …
2024年12月26日 · We simulate a meter-scale laboratory experiment in a numerical earthquake sequence model with stochastically variable normal stresses. We identify five regimes of …
Insights on earthquake nucleation revealed by numerical ... - Nature
2024年11月21日 · Understanding earthquake nucleation is vital for predicting and mitigating seismic events, saving lives, and enhancing construction practices in earthquake-prone areas. …
Preslip and cascade processes initiating laboratory stick slip
2014年7月9日 · Preslip is required to both generate the AE that could potentially cascade up, and weaken the surrounding fault in order to allow the cascade process to occur. Weak-but-abrupt …
Laboratory Observations of Tremor‐Like Events Generated During Preslip ...
2018年7月11日 · We conducted stick-slip experiments and observed tremor-like events and preslip in the laboratory. The results show the following. (1) The dominant frequency of tremor …
Laboratory Observations of Linkage of Preslip Zones Prior to
2018年8月24日 · The earthquake nucleation model was proposed for preslip or pre-rupture zones, while the meta-instability model was proposed for the overall stress release of the sample. …
(PDF) Competition between preslip and deviatoric stress …
2021年1月1日 · We perform a complementary set of stress oscillation experiments to quantify the response of seismic amplitudes and velocities to variations in the stress tensor. Taken …
