Buongiorno to everyone,
it is possible a quake of 4.2 will occur tomorrow morning, 2000/09/05, around 08.00 (local time)in central Italy, Lat 43N/Long 13E.

In negative case,just this predict quake could be occur in another place with the same magnitude around 300Km far Naples, but it will increase with more distance following:
more time/more distance/more magnitude
( concentric zones ).

From Pizza'City, Antonio.
