Fractal Dimension of the El Salvador Earthquake(2001) time Series

Earthquakes occur on the earth’s surface as a result of rearrangement of terrestrial cortex or higher part of the mantle. The energy released in this process propagates over long distances in the form of elastic seismic waves [1]. In order to predict earthquakes many models have been proposed [2, 3]. Dynamics of an earthquake is so complicated that it is quite difficult to predict using available models. Seismicity is a classic example of a complex phenomenon that can be quantified using fractal concepts [4]. In this paper we have estimated the fractal dimension, maximum, as well as minimum of the singularities, and the half-width of the multifractal spectrum of the El Salvador Earthquake signal at different stations. The data has been taken from the California catalogue (http://nsmp.wr.usgs.gov/nsmn eqdata.html). The paper has been arranged as follows: In section 2 the basic theory of multifractality has been discussed, and the results have been presented in section 3 .
