Statistical distribution of elapsed times and distances of seismic events: the case of the Southern Spain seismic catalogue

Several empiric cumulative distributions of elapsed times and distances between seismic events occurred in the Southern Iberian Peninsula from 1985 to 2000 (data extracted from the seismic catalogue of the Andalusian Institute of Geophysics) are investigated. Elapsed times and distances between cons...
