Axial Seamount Eruption Forecasting Experiment
Qinghua Lei, Didier Sornette, William W. Chadwick +3
We introduce the Axial Seamount Eruption Forecasting Experiment (EFE), a real-time initiative designed to test the predictability of volcanic eruptions through a transparent, physi…
Primary creep encodes time to failure across laboratory and natural systems
Qinghua Lei, Didier Sornette
Geomaterials often exhibit progressive creep characterized by an initial decelerating phase, frequently followed by an extended period of approximately constant deformation rate, a…
Universal scaling between precursory duration and event size across mechanically driven geohazards
Qinghua Lei, Didier Sornette
Many catastrophic events, including landslides, rockbursts, glacier breakoffs, and volcanic eruptions, are preceded by an observable acceleration phase that offers a critical windo…
Emergence of Finite-Time Singularities from Accelerated Event Recurrence: Insights into the Mechanism of Catastrophic Failure
Qinghua Lei, Didier Sornette
We develop a discrete-event modeling framework that captures the progression of geophysical systems toward catastrophic failure through sequences of distinct damage events. By repr…
Endo-exo classification of episodic rock creep in deep mines: Implications for forecasting catastrophic failure
Qinghua Lei, Daniel Francois Malan, Didier Sornette
Rock masses in deep underground environments under high in-situ stress often exhibit episodic creep behavior, driven by complex interactions between external perturbation and inter…
Endo-exo framework for a unifying classification of episodic landslide movements
Qinghua Lei, Didier Sornette
Landslides exhibit intermittent gravity-driven downslope movements developing over days to years before a possible major collapse, commonly boosted by external events like precipit…
