Bak and Tang : Earthquakes as a Critical Phenomenon
نویسنده
چکیده
The Gutenberg-Richter power law distribution for energy released at earthquakes can be understood as a consequence of the earth crust being in a self-organized critical state. A simple cellular automaton stick-slip type model yields D(E) • E -• with r = 1.0 and r = 1.35 in two and three dimensions, respectively. The size of earthquakes is unpredictable since the evolution of an earthquake depends crucially on minor details of the crust.

Unified scaling law for earthquakes.
We show that the distribution of waiting times between earthquakes occurring in California obeys a simple unified scaling law valid from tens of seconds to tens of years. The short time clustering, commonly referred to as aftershocks, is nothing but the short time limit of the general hierarchical properties of earthquakes. There is no unique operational way of distinguishing between main shock...
متن کاملSelf-organized Criticality: Sandpiles and Flux Lines
1. Self-Organized Criticality 1.1. Introduction There is an abundance of the scale invariant phenomena in nature, e.g. fractals, earthquakes, 1=f noise, uctuation of the stock index, etc. Scale invariance means that there are many scales (or equivalently, no typical scale) in the system. One asks why and how so many diierent scales emerge naturally in a physical system. In 1987, Bak, Tang, and ...
متن کاملE ects of Regulation on a Self { Organized
Adapting a simple biological model, we study the eeects of control on the market. Companies are depicted as sites on a lattice and labelled by a tness parameter (somècompany{size' indicator). The chance of survival of a company on the market at any given time is related to its tness, its position on the lattice and on some particular external innuence, which may be considered to represent regul...
متن کاملUniversality Classes in Isotropic, Abelian and non-Abelian, Sandpile Models
Universality in isotropic, abelian and non-abelian, sandpile models is examined using extensive numerical simulations. To characterize the critical behavior we employ an extended set of critical exponents, geometric features of the avalanches, as well as scaling functions describing the time evolution of average quantities such as the area and size during the avalanche. Comparing between the ab...
متن کامل0. Soc-like Models
A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it. It is a capital mistake to theorize before one has data. Is it SOC or not? asked Hendrik Jeldtoft Jensen in the final chapter of his book Self-Organized Criticality: Emergent Complex Behavior i...
