Well, Pat,
you are been very exaustive and clear.
I could be able to raise the percentage of chance strongly, but for doing it, I need to see the archive of EQs from 1985 to 1999 in the Mediterranean Area, I only have the Greek and few notices about Italy. Do you know the links where to go and see?

Where you sign 00/00/00, what means?
The exact day or a period from-to?

Thank for help.
Antonio
