Two-Phase Diagram of Earthquake Distributions
نویسنده
چکیده
This paper explains a model that shows that the conventional debate over whether earthquakes obey a Gutenberg-Richter Distribution or a Characteristic Distribution at a specific fault could be unfounded. The model, in the mean-field approximation, predicts a mode-switching phase and a Gutenberg-Richter phase that gives rise to the possibility of time-dependent seismic behavior. A qualitative phase diagram is obtained in parameter space and a second-order transition point is identified. Comparison with paleosiesmic data is made and discussed.

In this study, the effect of four-spin exchanges between the nearest and next nearest neighbor spins of honeycomb lattice on the phase diagram of S=3/2 antiferomagnetic Heisenberg model is considered with two-spin exchanges between the nearest and next nearest neighbor spins. Firstly, the method is investigated with classical phase diagram. In classical phase diagram, in addition to Neel order,...
متن کاملIntermittency 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...
متن کاملGutenberg 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...

In this paper, static and dynamic behavior of a varactor of a micro-phase shifter under DC, step DC and AC voltages and effects of the residual stress on the phase diagram have been studied. By presenting a mathematical modeling, Galerkin-based step by step linearization method (SSLM) and Galerkin-based reduced order model have been used to solve the governing static and dynamic equations, resp...

Experimental determination of solubility and ternary phase diagram of chiral compound are of tedious and time consuming tasks, and in many cases, there is not enough experimental data for different enantiomeric compositions to access the experimental ternary phase diagram. Using thermodynamic models with predictive capability, having less dependency on experimental data, affords a great advanta...
