Rainfall patterns and related landslide incidence in the Porretta-Vergato region, Italy

Abstract: An analysis of landslide occurrence in the low permeability terrain of Porretta-Vergato, Italy, related to prolonged rainfall patterns is presented. Data sets collected over nearly a century are statistically analysed. The pattern of the landslide hazard is considered and related to precipitation at the basin scale in order to enhance the understanding between the two parameters and assess their temporal changes, as well as interrelationships. Landslide incidence generally follows the periodic pattern of preci… Show more

“…Trend and correlation analyses between landslide occurrence and related rainfall or soil moisture conditions are part of a large number of recent studies. Much of these investigations were conducted for study areas located in humid mid-latitude regions (e.g., Chleborad 2003;Jakob and Weatherly 2003;Ibsen and Casagli 2004;Zêzere et al 2005;Cardinali et al 2006;Jakob et al 2006;Guzzetti et al 2007;Saito et al 2010). The studies of , , , , and Yeh and Lee (2013) are among those that also consider antecedent moisture conditions and critical soil water contents in the development of rainfall thresholds.…”

“…Shallow landslides and debris flows occur in smaller numbers, but their occurrence has markedly increased in the last few years (Martina et al 2010). Even if a significant number of landslides is triggered by snow melting (Martelloni et al 2013), rainfall is by far the main triggering factor: debris flows and shallow landslides are triggered by short but exceptionally intense rainfall, while deep-seated landslides and earth flows have a more complex response to rainfall and are mainly influenced by moderate but exceptionally prolonged (even up to 6 months) periods of rainfalls (Ibsen and Casagli 2004;Benedetti et al 2005).…”

“…In general, the main triggering factor of all the Emilia Romagna landslides is rainfall. Two different kinds of precipitations can be associated with the initiation of different landslide typologies: debris flows and shallow landslides are usually triggered by short but exceptionally intense rainfalls, while deep-seated landslides and earthflows have a more complex response to rainfalls and are mainly influenced by moderate but exceptionally prolonged (even up to 6 months) periods of rainfalls (Ibsen and Casagli 2004;Benedetti et al 2005).…”

“…First of all, the study area was partitioned into 19 territorial units (TU), chiefly defined on the basis of different physiographic and environmental features (meteorological, lithological and geographical data) following the approach of previous works (Bertolini and Pellegrini 2001;Ibsen and Casagli 2004;Benedetti et al 2005) (Fig. 3).…”
