A Struggled Rupture Initiation of the Mw 6.1 2009 L’Aquila Earthquake
Geophysical Research Letters, 2023 Understanding under which physical conditions large earthquakes begin, is a key question in Earth science. Laboratory experiments and numerical models have shown that earthquake nucleation has distinct phases: a quasi‐static and an acceleration stage ...

Nucleation process of the 2011 northern Nagano earthquake from nearby seismic observations
Scientific Reports, 2021 The 2011 magnitude (M) 9.0 Tohoku-oki earthquake was followed by seismicity activation in inland areas throughout Japan. An outstanding case is the M6.2 Northern Nagano earthquake, central Japan, occurred 13-h after the megathrust event, approximately ...

Deep Underground Science and Engineering, EarlyView.Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

, 2018 The earthquake activity in Oklahoma and Kansas that began in 2008 reflects the most widespread instance of induced seismicity observed to date. We develop a reservoir model to calculate the hydrologic conditions associated with the activity of 902 ...

Modeling proppant transport and settling in a 3D propagating fracture
Deep Underground Science and Engineering, EarlyView.A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Optimized Traffic Light System with AIC and Application to the 2021 M6.7 Yangbi Earthquake Sequence
Entropy, 2023 One important question in earthquake prediction is whether a moderate or large earthquake will be followed by an even bigger one. Through temporal b-value evolution analysis, the traffic light system can be used to estimate if an earthquake is a ...

Deep Underground Science and Engineering, EarlyView.Rock fracture can ultimately be traced to atomic bond breakage. Taking quartz as a representative mineral, this paper employs molecular dynamics to identify the crack initiation and propagation mechanisms for single‐hole cases, as well as crack coalescence modes between double holes under compression, providing a physical basis for multiscale modeling ...
