|Issue Date: ||2006|

|Abstract: ||In any probabilistic seismic hazard assessment an important role is played by the seismicity rates. This is confirmed by the wide and
controversial discussions about the procedures for their determination: Gutenberg and Richter distribution vs independent rates in
every magnitude class ; size of binned magnitude class; the fitting algorithm to use (least squares or maximum likelihood); and so on.
In 2004 a new probabilistic seismic hazard map of Italy, named MPS04 (MPS04 Working Group, 2004), was released adopting a logic tree
approach for exploring the alternative epistemic choices (Fig. 1). For seismogenic zonation (ZS9, MPS04 Working Group, 2004) (Fig. 2)
and catalogue (CPTI04; CPTI04 Working Group, 2004) no alternative models were explored.|
