Abstract. The paper reports field data provided by the automatic monitoring of the annual hydrological response of a shallow deposit of loose pyroclastic soils located in a mountainous area of Campania, Southern Italy. The monitoring station is installed along the northern slope of mount Cornito, about 2 km east of the town of Cervinara, which in December 1999 had been involved in a rainfall-induced flowslide. The collected data concern rainfall height, soil moisture content and suction. In particular, the installation at the same depths of suction and moisture sensors allows to estimate the soil water retention features that seem to indicate some hysteretic nature of the wetting/drying processes induced by weather conditions and their influence on the local stability conditions.

The data reported in the paper are freely available at (Comegna et al., 2020).

Short summary
The setup of an automatic field station allowed monitoring the annual cyclic hydrological response of a deposit in pyroclastic airfall soils covering a steep mountainous area in Campania Region (Southern Italy), which in 1999 was involved in a rainfall-induced flowslide. Collected data highlight the influence of the initial conditions, governed by the antecedent wetting/drying history, on the weather-induced hydraulic paths, allowing to estimate their influence on the local stability conditions.
