We investigated by fractal tools the temporal patterns of 1996-1999 seismicity of the Umbria-Marche region, central Italy, that was struck by a strong event ðM S ¼ 5:9Þ on September 26, 1997. Clustering behaviour has been evidenced by using different fractal tools, Fano factor analysis, Allan factor
