Thank you! Actually, entire Amalfi coast looks something like this, with villages located right on the cliffs as if one above another (Positano is most spectacular one though). There are earthquakes in Italy quite often and some strong ones also do occur but if they happen it is usually around Abruzzo region and it is far enough for Amalfi to be safe. As far as I know none of the earthquakes arrived so far to disrupt peace and quite of Amalfi. :)
