...As a result, inventory maps produced by different investigators can be difficult to compare (Roth, 1983; Carrara et al., 1992; Ardizzone et al., 2002; van Westen et al., 2006; Galli et al., 2008)....

...…in all continents, and even for parts of other planets (e.g., Quantin et al., 2004), the criteria for the production of landslide maps and for the evaluation of their quality remain poorly defined (Soeters and van Westen, 1996; Guzzetti et al., 2000; Guzzetti, 2006; van Westen et al., 2006, 2008)....

...In addition, almost the entire world is now covered by a DEM with a spatial resolution of 30 m (outside of the US distributed at 90 m) from the NASA Shuttle Radar Topography Mission (SRTM) (Rabus et al. 2003), which serves as a good basis for landslide studies at regional scales....

...One of the most useful definitions of risk is presented by Varnes (1984) as ‘‘the expected number of lives lost, persons injured, damage to property and disruption of economic activity due to a particular damaging phenomenon for a given area and reference period’’....

...Schematically, this can be represented by the following formula, based on Varnes (1984), Fell (1994), Leroi (1996) and Lee and Jones (2004): Risk = X H X ðVAÞ ð1Þ where: H Hazard expressed as probability of occurrence within a reference period (e.g., year, design period of a building)....
