Log‐Periodic Power Law Singularities in Landslide Dynamics: Statistical Evidence From 52 Crises by Qinghua Lei, Didier Sornette

“…We propose that such intermittent rupture phenomena can be described by a log‐periodic power law singularity model. Amounting mathematically to a generalization of the power law exponent from real to complex numbers, this model captures the partial break of continuous scale invariance to discrete scale invariance that is inherent to the intermittent dynamics of damage and rupture processes in heterogeneous geomaterials. …”
