Abstract:	摘要： In this study, we investigated the quasi-periodicity of large avalanches using a new modification of sandpile models, i.e., the long-range connective sandpile (LRCS) model. The LRCS model considers the random distant connection between two separated, instead of neighboring, cells and shows interesting precursory behavior before large avalanches. We explore the statistics of recurrence intervals between large events and find a strong dependence on the size L of the sandpile. In the LRCS model, the average recurrence interval W of large avalanches follows the relationship . Having the recurrence intervals of many earthquake fault systems around the world, we propose an empirical rule between those intervals and the corresponding earthquakes' magnitudes and provide evidence of the quasi-periodic behavior of natural earthquakes. 其他題名： EPL 出版者： Les Ulis: EDP Sciences, IOP Publishing and Società Italiana di Fisica 出版日期： 2014-02-01 出處： Europhysics letters, 2014-02, Vol.105 (4), p.40003-p1-40003-p6 資源來源： IoP Science journals 版權： Copyright © EPLA, 2014 識別號： ISSN: 0295-5075 識別號： EISSN: 1286-4854 識別號： DOI: 10.1209/0295-5075/105/40003 識別號： CODEN: EULEEJ
