Gutenberg Richter and Characteristic Earthquake behavior in Simple Mean-Field Models of Heterogeneous Faults
The statistics of earthquakes in a heterogeneous fault zone is studied analytically and numerically in a mean field version of a model for a segmented fault system in a three-dimensional elastic solid [1,2]. The studies focus on the interplay between the roles of disorder, dynamical effects, and driving mechanisms. A two-parameter phase diagram is found, spanned by the amplitude of dynamical we...
متن کاملComment on " The Gutenberg - Richter or Characteristic Earthquake Distribution , Which Is It ? " by Steven
In a recent article, Wesnousky (1994) (henceforth referred to as Wesnousky) analyzes seismicity and geologic deformation rates for five faults in southern California and arrives at the conclusion that the characteristic model yields a better description of the earthquake size statistical distribution than the Gutenberg-Richter (G-R) magnitude-frequency law. To analyze earthquake occurrences in ...
متن کاملShort Note Is There a Basis for Preferring Characteristic Earthquakes over a Gutenberg–Richter Distribution in Probabilistic Earthquake Forecasting?
The idea that faults rupture in repeated, characteristic earthquakes is central to most probabilistic earthquake forecasts. The concept is elegant in its simplicity, and if the same event has repeated itself multiple times in the past, we might anticipate the next. In practice however, assembling a fault-segmented characteristic earthquake rupture model can grow into a complex task laden with u...
متن کاملGutenberg-Richter Statistics in Topologically Realistic System-Level Earthquake Stress-Evolution Simulations
We discuss the problem of earthquake forecasting in the context of new models for the dynamics based on statistical physics. Here we focus on new, topologically realistic system-level approaches to the modeling of earthquake faults. We show that the frictional failure physics of earthquakes in these complex, topologically realistic models leads to self-organization of the statistical dynamics, ...
متن کاملNear-mean-field behavior in the generalized Burridge-Knopoff earthquake model with variable-range stress transfer.
Simple models of earthquake faults are important for understanding the mechanisms for their observed behavior in nature, such as Gutenberg-Richter scaling. Because of the importance of long-range interactions in an elastic medium, we generalize the Burridge-Knopoff slider-block model to include variable range stress transfer. We find that the Burridge-Knopoff model with long-range stress transf...
