I n 1989 the Minister of Civil Protection asked the National Research Council, Group for Geological and Hydrological Disasters Prevention, to complete a inventory of the areas historically affected by landslides and floods in I taly.
THE AVI PROJECT THE AVI PROJECT
To respond to the Minister request, in 1990-92 we designed and completed a bibliographical and archive inventory of historical information on landslides and floods in I taly. The inventory became known as the “AVI project”.

GNDCI THE AVI PROJECT RESULTS THE AVI PROJECT RESULTS
Through the analysis of 500,000 newspapers, 1500 scientific reports, and interviews to 300 experts, we collected 22,700 information on landslides and 7,800 information on floods. 23,600 landslide events at 15,900 sites, and 25,000 flooding events at 13,400 sites were identified and mapped at 1:100,000 scale. Of the 8103 I talian municipalities, 4,528 (55% ) were affected at least once by a landslide and 4,200 by a flood (52% ).
