Hi Canie. I saw a program either on The Learning Channel or Discovery Science Channel a few months ago and they were showing film and interviewing people from the last damaging earthquakes in Italy. Perhaps you have seen the footage where they are in the church and they are reviewing the damage and a second quake strikes causing the ceiling to collapse and 4 more people were killed? Anyway a gentleman that was being interviewed made an interesting comment. He said that they never have one earthquake there, they always have 3 within a matter of days. So far it looks like he knew what he was talking about.
