Self-organized criticality in a continuous, nonconservative cellular automaton modeling earthquakes.

چکیده
We introduce a new nonconservative self-organized critical model. This model is equivalent to a quasistatic two-dimensional version of the Burridge-KnopoA spring-block model of earthquakes. Our model displays a robust power-law behavior. The exponent is not universal; rather it depends on the level of conservation. A dynamical phase transition from localized to nonlocalized behavior is seen as the level of conservation is increased. The model gives a good prediction of the Gutenberg-Richter law and an explanation to the variances in the observed b values.

Self-organized criticality: Does it have anything to do with criticality and is it useful?
Three aspects of complexity are fractals, chaos, and self-organized criticality. There are many examples of the applicability of fractals in solid-earth geophysics, such as earthquakes and landforms. Chaos is widely accepted as being applicable to a variety of geophysical phenomena, for instance, tectonics and mantle convection. Several simple cellular-automata models have been said to exhibit ...
متن کاملCriticality in driven cellular automata with defects
We study three models of driven sandpile-type automata in the presence of quenched random defects. When the dynamics is conservative, all these models, termed the random sites (A), random bonds (B), and random slopes (C), selforganize into a critical state. For Model C the concentration-dependent exponents are nonuniversal. In the case of nonconservative defects, the asymptotic state is subcrit...
متن کاملModeling geocomplexity: “A new kind of science”
A major objective of science is to provide a fundamental understanding of natural phenomena. In “the old kind of science” this was done primarily by using partial differential equations. Boundary and initial value conditions were specified and solutions were obtained either analytically or numerically. However, many phenomena in geology are complex and statistical in nature and thus require alt...
متن کاملParallel and distributed simulations and visualizations of the Olami–Feder–Christiensen earthquake model
In this work we present some numerical results and visualizations obtained from parallel and distributed simulations of the Olami–Feder–Christiensen earthquake model. This model is a two-dimensional cellular automata, continuous in space and discrete in time, constructed in order to simulate earthquake activity and it was introduced as a generalization of the one-dimensional spring block model ...
متن کاملA minimalist model of characteristic earthquakes
In a spirit akin to the sandpile model of selforganized criticality, we present a simple statistical model of the cellular-automaton type which simulates the role of an asperity in the dynamics of a one-dimensional fault. This model produces an earthquake spectrum similar to the characteristic-earthquake behaviour of some seismic faults. This model, that has no parameter, is amenable to an alge...
