“…Whilst in the Italian Alps, due to their high frequency, flash floods in small basins have been the subject of detailed studies for many decades (Crosta and Frattini, 2004;Sosio et al, 2007;Carrara et al, 2008;Simoni et al, 2011;Arattano et al, 2012Arattano et al, , 2015Marchi and Tecca, 2013;Berti and Simoni, 2014;Blahut et al, 2014;Tiranti et al, 2014), in the Apennines they have typically been analyzed with less attention (Sorriso Valvo et al, 1998;Zanchetta et al, 2004a;Santo et al, 2002Santo et al, , 2015Garfì et al, 2007;Cascini et al, 2008a;Santangelo et al, 2011Santangelo et al, , 2012Alessio et al, 2013;Antronico et al, 2015a, b;Scorpio et al, 2016).…”

Abstract. This study presents an historical database of flash flood events in the Campania region of southern Italy. The study focuses on small catchments characterized by intermittent flow, generally occurring during and after heavy rainstorms, which can be hydrologically defined as small Mediterranean catchments. As the outlet zones of these catchments (consisting mainly of alluvial fans or fan deltas) are highly urbanized in Campania, the population living in the delivery areas is exposed to high risk. Detailed scrutiny and critical analysis of the existing literature, and of the data inventory available, allowed us to build a robust database consisting of about 500 events from 1540 to 2015, which is continuously updated. Since this study is the first step of a longer project to perform a hazard analysis, information about time and site of occurrence is known for all events. As for the hazard analysis envisaged, collecting information about past events could provide information on future events, in terms of damage and also spatial and temporal occurrence. After introducing the issue of flash floods in Italy we then describe the geological and geomorphological settings of the study area. The database is then presented, illustrating the methodology used in collecting information and its general structure. The collected data are then discussed and the statistical data analysis presented.

“…An interesting example of slopes where a fine-textured soil overlies a more permeable one is in Pizzo d'Alvano (Campania, Southern Italy) where a lot of landslides (debris flows and debris avalanches) were triggered by prolonged rainfalls in May 1998 (Del Prete et al 1998;Crosta and Dal Negro 2003;Guadagno et al 2003Guadagno et al , 2005Revellino et al 2004;Cascini et al 2008). Landslides were triggered by the sliding of superficial pyroclastic debris from the covering mantle and were subsequently channelized as debris flows (Fiorillo et al 2001;Crosta and Dal Negro 2003;Revellino et al 2004).…”

The paper presents a preliminary, simplified evaluation of the effects of rainfall infiltration on the stability of slopes in layered pyroclastic soils affected by shrinkage vertical fractures. The analysis has been developed with a special reference to a stratigraphic sequence obtained by an in situ survey at Pizzo d'Alvano (Southern Italy). The analysis of rainfall infiltration is performed using an original dual-permeability model. Results show how fractures strongly condition infiltration depending on rainfall intensity. Prolonged low-intensity rainfall may lead to a higher saturation of the surface soil layer than short, intense rainfall when water may flow quickly through fractures into the underlying more permeable soil layers. Calculated distributions of pore pressure are used for the slope stability analysis using the infinite slope approach. Variations of the safety factor as a consequence of infiltration show that prolonged rainfall can induce a more relevant decrease in the safety factor than intense precipitations.

“…The paper deals with an unsaturated air-fall volcanic (pyroclastic) soil of Southern Italy, originated from the explosive activity of the Somma-Vesuvius volcano [12]. In particular, the pyroclastic deposits mantling the Pizzo d'Alvano massif have been extensively tested after the huge flowslides occurred in May 1998, which damaged four towns at the toe of the massif [12].…”

Abstract. The so-called wetting-induced collapse is one of the most common problems associated with unsaturated soils. This paper applies the Modified Pastor-Zienkiewicz model (MPZ) to analyse the wetting behaviour of undisturbed specimens of an unsaturated air-fall volcanic (pyroclastic) soil originated from the explosive activity of the Somma-Vesuvius volcano (Southern Italy). Both standard oedometric tests, suction-controlled oedometeric tests and suction-controlled isotropic tests are considered. The results of the constitutive modelling show a satisfactory capability of the MPZ to simulate the variations of soil void ratio upon wetting, with negligible differences among the measured and the computed values.
