While almost all types of natural hazards occur throughout Italy, the most dangerous ones would have to be earthquakes, land subsidizing, and flooding.
The Italian coastline consists of about half low or delta coastlines, 3200 km of sand or gravel beaches, and the rest is hanging cliffs that drop off into the ocean.
Venice is probably the city most affected by land subsidence. It has been sinking each year more than it ever has within the past century at about one to two millimeters per year.
While natural disasters such as volcanic eruptions and high magnitude earthquakes occur less frequently in Italy, landslides bring destruction year round.
Since the beginning of the common era, about 72 tsunamis have affected the coastal towns of Italy. Most of them have been of minor intensity but some very destructive.
