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…
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…
Oscillatory finite-time singularities in rockbursts
Qinghua Lei, Didier Sornette
Forecasting violent rockbursts remains a formidable challenge due to significant uncertainties involved. One major uncertainty arises from the intermittency of rock failure process…
Log-Periodic Precursors to Volcanic Eruptions: Evidence from 34 Events
Qinghua Lei, Didier Sornette
Forecasting volcanic eruptions remains a formidable challenge due to the inherent complexity and variability of volcanic processes. A key source of uncertainty arises from the spor…
Log-Periodic Power Law Singularities in Landslide Dynamics: Statistical Evidence from 52 Crises
Qinghua Lei, Didier Sornette
Landslide movements typically show a series of progressively shorter quiescent phases, punctuated by sudden bursts during an acceleration crisis. We propose that such intermittent…
