The role of heterogeneity in long-range interacting systems : from nucleation to earthquake fault systems [PDF]

, 2016
The role of heterogeneity in two long-range systems is explored with a focus on the interplay of this heterogeneity with the component system interactions. The first will be the heterogeneous Ising model with long-range interactions.

Foreshocks of the 2016 MS5.1 Yunlong earthquake in Western Yunnan, China, and implications for earthquake nucleationKey points

Earthquake Science
Monitoring the evolution of foreshocks can be a valuable way to analyze the nucleation process. Foreshocks accompanying moderate mainshocks have been recorded in the west of Yunnan Province, China.

Earthquake nucleation and fault slip complexity in the lower crust of central Alaska [PDF]

, 2018
International audienceEarthquakes start under conditions that are largely unknown. In laboratory analogue experiments and continuum models, earthquakes transition from slow-slipping, growing nucleation to fast-slipping rupture.

The structure and composition of exhumed faults, and their implications for seismic processes [PDF]

, 2000
Field studies of faults exhumed from seismogenic depths provide useful data to constrain seismologic models of fault zone processes and properties. Data collected on the San Andreas Fault in the San Gabriel Mountains has shown that large-displacement ...

Insights on Earthquake Nucleation Revealed by Numerical Simulation and Unsupervised Machine Learning of Laboratory-Scale Earthquake Nucleation

Abstract Understanding earthquake nucleation is vital for predicting and mitigating seismic events, saving lives, and enhancing construction practices in earthquake-prone areas. Cascade triggering and preslip triggering are prevalent theories, posing challenges in differentiation based on field observations.

The Effects of Characteristic Weakening Distance on Earthquake Nucleation Styles in Fully Dynamic Seismic Cycle Simulations

Earthquake nucleation is a crucial preparation process of the following coseismic rupture propagation. Under the framework of rate-and-state friction (RSF), it was found that the ratios of a $a$ to b $b$ parameters control whether earthquakes nucleate as

Latitude-Time Total Electron Content Anomalies as Precursors to Japan's Large Earthquakes Associated with Principal Component Analysis

International Journal of Geophysics, 2011
The goal of this study is to determine whether principal component analysis (PCA) can be used to process latitude-time ionospheric TEC data on a monthly basis to identify earthquake associated TEC anomalies.

Detecting sub-instability before three Mw > 6.0 earthquakes on Chinese mainland in 2020–2022 with load/unload response ratio

Geomatics, Natural Hazards & Risk
The sub-instability refers to a stress state that exists between the maximum stress the rock can withstand and its final failure. This stress state should be an indicator of impending large earthquakes, as it occurs in the final stage of earthquake ...

The mixed mechanisms of large‐earthquake nucleation

Eos, Transactions American Geophysical Union, 2013
Where do big earthquakes come from? That's an important open question in seismology. High‐energy earthquakes often come from faults under high strain, but the mechanism that underlies their onset is still debated.
