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…
Generalized failure law for landslides, rockbursts, glacier breakoffs, and volcanic eruptions
Qinghua Lei, Didier Sornette
Catastrophic failures have momentous impact in many scientific and technological fields but remain challenging to understand and predict. One key difficulty lies in the burstiness…
