abstract = {The goal of this contribution is to develop a set of methods and techniques for modelling
landslide hazard, in order to obtain better predictions and, therefore, to reduce the risk
associated to this type of process. The research has been carried out in North-Western
Guipúzcoa (Spain), an area intensely affected by shallow landslides. Hazard predictions
must be based on several assumptions, termed scenarios. To propose more realistic hazard
scenarios, two different approaches have been applied: on one hand, by extrapolating the
trends observed from recent past landslide activity and, on the other hand and indirectly,
from the empirical analyses between landslides and their main trigger (precipitation). It was
necessary to get long time series of landslide occurrences, through which sound future
frequency could be estimated and relationships between landslides and their predisposing
factors established. The landslide inventory includes 20 time intervals ranging from the 50s
of last century to the present and has been obtained by analyzing photographic images from
different dates. Rainfall records of several weather stations have been analyzed, establishing
correlations between landslides and precipitation intensity-duration. According to rainfall
quantity, duration and intensity, as well as landslide activity, six multiple occurrence
regional landslide events (MORLE), regarding rainfall extreme events, have been identified
and characterized. On the basis of both types of scenarios quantitative hazard models could
be obtained.},
