PHYSICAL FRACTAL AND R/S ANALYSIS OF TIME AND SPACE CLUSTERING OF EARTHQUAKES IN WESTERN HUBEI AND ITS SURROUNDING AREAS
摘要
Abstract
The historical earthquake catalogues (M ≥4. 5)and 1970-2010 earthquake catalogues( M≥1.0)in western Hubei and its surrounding areas are analyzed with the methods of physical fractal and R/S analysis. Accordingly, the natural cycle, fractal dimension and fractal scale-less range form every subset of small earthquakes are obtained,and the Hurst exponent (0. 79) of earthquake frequency sequences and Hurst exponent (0. 87) of earthquake timing interval sequences are obtained as well. Thereby the self-similarity and hierarchical structure of these earthquakes are revealed.关键词
