More people will probably be exposed to shallow, rapid-moving landslides. The number of deep-seated, slower landslides, that cause a lot of economic damage, will probably decrease.
Annual number of landslides in central Italy will increase by 30% and 45% for 2040-2069 and 2070-2099, respectively. This is due to an increase of rainfall intensity in the hours prior to landslides.Read more »
Melting glaciers and thawing of permafrost have caused stream discharge to almost double in Alpine watersheds through the last five decades. A frequent outcome of rapid climate warming.Read more »
For the Alps, the main trigger of debris flows is high intensity, short duration rainfall. Under future climate change, it is likely that increases in extreme rainfall will alter debris flow frequencyRead more »
In Italy, landslides are a serious threat to the population: in the period 1954–2013 1279 persons were killed and 1731 were injured by landslides. Rainfall is the primary triggerRead more »
In Portugal, during 1865-2010 1,621 disastrous floods and 281 disastrous landslides were recorded that led to casualties or injuries, andRead more »
