Intermittency of earthquake cycles in a model of a three-degree-of-freedom spring-block system

We herein report the results of some numerical simulations of complex earthquake cycles using a threedegree-of-freedom spring-block model with a rateand statedependent friction law. The model consists of three blocks on a conveyor belt that is moving at a steady rate. Observed complex slip behaviour in the simulations is classified into five slip patterns, and for each of these the parameter de...

Non-linear dynamics of a continuous spring–block model of earthquake faults

The continuous one-dimensional Burridge–Knopoff model is generalized by introducing plastic creep in addition to rigid sliding. The resulting equations, for an order parameter (sliding rate) and a control parameter (driving force), exhibit a velocity-strengthening and a velocity-softening instability. In the former regime, considered to be the analog of self-organized criticality in continuum s...

Self-organized criticality and deterministic chaos in a continuous spring–block model of earthquake faults

Starting off from the relationship between time-dependent friction and velocity softening, the paper presents a generalization of the continuous version of the one-dimensional homogeneous, deterministic Burridge–Knopoff (BK) model by allowing for displacements by plastic creep and rigid sliding. The evolution equations describe the coupled dynamics of an order parameterlike field variable (the ...

On the separation of timescales in spring-block earthquake models

One of the most widespread spring-block earthquake models, the Olami-Feder-Christensen model, is investigated without making the assumption that the duration of individual earthquakes is negligible. While the GutenbergRichter law for the size distribution of earthquakes is preserved qualitatively for earthquakes of finite duration, the bvalue decreases with increasing earthquake duration. The e...

Spring-Block Model Reveals Region-Like Structures

A mechanical spring-block model is used for realizing an objective space partition of settlements from a geographic territory in region-like structures. The method is based on the relaxation-dynamics of the spring-block system and reveals in a hierarchical manner region-like entities at different spatial scales. It takes into account in an elegant manner both the spatiality of the elements and ...
