Scaling in a Nonconservative Earthquake Model of Self-Organised Criticality
Stefano Lise, Maya Paczuski
We numerically investigate the Olami-Feder-Christensen model for earthquakes in order to characterise its scaling behaviour. We show that ordinary finite size scaling in the model…
Self-Organized Criticality and Universality in a Nonconservative Earthquake Model
Stefano Lise, Maya Paczuski
We make an extensive numerical study of a two dimensional nonconservative model proposed by Olami-Feder-Christensen to describe earthquake behavior. By analyzing the distribution o…
Universal Fluctuations in Correlated Systems
S. T. Bramwell, K. Christensen, J. -Y. Fortin +7
The probability density function (PDF) of a global measure in a large class of highly correlated systems has been suggested to be of the same functional form. Here, we identify the…
Transitions in non-conserving models of Self-Organized Criticality
Stefano Lise, Henrik Jeldtoft Jensen
We investigate a random--neighbours version of the two dimensional non-conserving earthquake model of Olami, Feder and Christensen [Phys. Rev. Lett. {\bf 68}, 1244 (1992)]. We show…
