| Significant power-law long-range correlated structures have been identified
in the Italian seismicity from 1983 to 2003. We performed the Allan Factor
Analysis and the Detrended Fluctuation Analysis on both the full and the
aftershock-depleted seismic data, extracted by the INGV (National Institute
of Geophysics and Volcanology) instrumental catalog.Our findings suggest that (i) the time-scaling behaviour
characterizes mainly the Apennine chain; (ii) the time-correlated behaviour
of the seismicity is persistent, and this implies that the dynamics
underlying the seismic phenomenology is characterized by the presence of
"positive feedback mechanisms"; (iii) significant time correlation is not
simply related with the mainshock/aftershock mechanisms. |
