Identifying spatial clustering properties of the 1997-2003 Liguria (Northern Italy) forest-fire sequence

The spatial clustering of the forest-fire sequence (1997-2003) of Liguria Region (Northern Italy) has been analysed using the correlation dimension D-C, calculated by means of the correlation integral method. Studying the variations of this parameter, we recognize the presence of a strong variability of the spatial clusterization, modulated by seasonal cycles. Furthermore, we found that the larger fires (size > 400 ha) mark the cyclic behaviour of the correlation dimension.
