Abstract: The idea of presenting this paper appeared after reading the article of C.J. van<br />
Westen et al., from 2005, c<strong>on</strong>cerning the difficulties encountered in assessing hazard and<br />
risk to landslide. As Romania is located in Europe as <strong>on</strong>e of first places, unfortunately,<br />
regarding the effect of these phenomena, we c<strong>on</strong>sidered appropriate to deal with the<br />
subject. According to van Westen, even though in recent years the literature has shown a<br />
development in hazard and risk estimati<strong>on</strong> with geotechnics, by in situ investigati<strong>on</strong>s,<br />
development of hazard maps and risk assessment to landslides, procedures absolutely<br />
necessary for regulatory and development planning by authorities, this acti<strong>on</strong>s still remain<br />
a far end goal, especially to medium scale (1:10.000- 1:50.000). In this article we try to<br />
illustrate the difficulties encountered in our attempt to develop landslide hazard maps at a<br />
regi<strong>on</strong>al scale. Thus, we present the difficulties arising in the inventory of this kind of<br />
phenomena, including informati<strong>on</strong> <strong>on</strong> the occurrence, type and volume of landslides,<br />
establishment of spatial and temporal probability of release, vulnerability assessment etc.<br />
In light of the above, we illustrate the hazard maps developed by our team, presenting<br />
hence the problems we faced. The major issues to be solved did not regard legislati<strong>on</strong>,<br />
which is by far thick, but access to the necessary informati<strong>on</strong> to elaborate maps, according<br />
to the Methodological Norms in Force, uncertainty about quality and accuracy of these<br />
informati<strong>on</strong> and the list may go <strong>on</strong>.<br />
Key words: landslide hazard, vulnerability, spatial and temporal probability.<br />
