- A qualitative comparison between some synthetic and empirical scaling properties in seismicity A. Muñoz-Diosdado A.H. Rudolf-Navarro F. Angulo-Brown Física, Astronomía y Matemáticas self Spring block model seismicity patterns organized criticality Earth’s crust can be conceived as a hierarchical set of objects of many shapes and sizes with fractal behavior. In fact, many geological phenomena are scale free. Self similar behavior is reflected in several empirical power-laws in geology and geophysics that have been found during more than a century. The scale invariance requires power law dependence between the number of objects of a specific size with the size. So an earthquake-fault model has to be able to produce these scaling relations. Within the context of self-organized critical systems, Olami, Feder and Christensen (OFC) proposed a nonconservative spring–block earthquake model that reproduces some seismic properties such as the Gutenberg-Richter (G-R) law for the size distribution of earthquakes. In the present article we analyze some statistical properties of a spring-block model and we compare them with the corresponding statistical properties of actual seismicity of the Mexican South Pacific Coast. We have showed that by means of the OFC model is possible to find G-R laws and staircase plots that are at least qualitatively analogous to the corresponding G-R laws and staircase plots of actual seismicity. It is remarkable that synthetic OFC-seismicity is characterized by a kind of attractor consisting of a straight line whose slope attracts the long-term cumulative seismicity. Unfortunately, the actual Mexican seismicity catalogues are yet too short to completely contrast this synthetic seismicity property. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030391017 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
