Rainfall thresholds for the possible initiation of rainfall-induced landslides in Apulia (SANF Puglia)

Background

In Italy rainfall are among the main causes of trigger of shallow landslides, that yearly cause fatalities, damage, and severe economic losses. Identification of the amount of rainfall needed to trigger landslides, and the forecasting of rainfall-induced landslides, are of interest for the scientific community, as well as for the whole population.

Purpose

Collect, organize and analysis of metereologic and geomorphological informations on rainfall-induced landslides in Apulia. Definition of empirical pluviometric thresholds for the forecast of the likely trigger of landslides. Validation of the forecasts of the national alert system for the forecast of rainfall-induced landslides. Educational activity and support for reconnaissance activities of freelance geologists.

Methods

The rainfall data associated to the landslide occurrence will be used to define new pluviometric thresholds for the likely onset of instability processes in Apulia; the thresholds will be of the type cumulate-duration (ED) and/or intensity-duration (ID). Methods and procedures established by CNR IRPI will be used to compute the pluviometric thresholds.
