This area has been recently studied in detail through geophysical techniques, which have been applied to the landslide of Monte Di Vezzi (Di Maio et al. 2007) that occurred in April 2006 involving the northern slope of Ischia (Di Nocera et al. 2007). The Monte di Vezzi belongs to a ridge stretching in a counter-Apenninic (NE-SW) direction. Ischia is a densely inhabited volcanic island with a long eruptive history lasting more than 150 ka (last in 1302 AD) characterized by the significant asymmetric resurgence of a caldera block. Here, we review the state-of-art of the natural hazards of Ischia, aiming at building a solid base for future holistic multi-hazard quantifications.

Their deposits are covered by thick lava fountains deposits, related to eruptive fractures (Torone, Monte di Vezzi, 130 ka). At around 117 and 100 ka ago, lava flows and lava domes were emplaced. An explosive paroxysm is recorded in the volcanic successions around 100 ka ago; deposits of Plinian events form L'Elefante and Spiaggia d'Agnone. Volcanic activity at Ischia Island encompasses five phases, aged between 150 ky B.P. and 1302 A.D. Different stages of volcanic activity implied different volcano-tectonic events, summarized as follows: a) Epomeo horst resurgence, b) built of the structural highs of Mt. Vico, Mt. Panza (at west), Mt. di Vezzi, Mt. Torone, Mt. Campagnano (at east), c) Ischia graben development in the eastern.

During the eruptive phases following the eruption of the Epomeo Green Tuffs (55 ky B.P.), the La Guardiola lava has been overlain by the Monte di Vezzi Formation, composed of not welded pumice flows erupted from the Epomeo Green Tuff, by the S. Costanzo Formation, composed of white tuffs, well stratified, with pumice, by the Monte di Vezzi. We present a magnetic and gravimetric study of the structural setting of the Monte di Vezzi area, in the Ischia Island. The study was performed carrying out an analysis of a new high-resolution aeromagnetic data set and a previous gravity data set. The aeromagnetic survey covered the entire area of the island with a flight line spacing and a clearance of 300 meters. In this paper, a reappraisal of the Quaternary geologic evolution of Ischia based on literature data is advised, concentrating on the volcanology of the island, based on field data and geochemistry, due to the happening of active fumarolic systems on the island and the marine geology and geophysics, which are intensively studied in the frame of t. A regional survey was undertaken to define the stratigraphic sequence on Ischia between ∼75 and 50 ka BP (Fig. 2).The succession has been pieced together from widely scattered outcrops around Ischia, Procida and Monte di Procida (SW Campi Flegrei, Fig. 1).The sequence is complex, but is stratigraphically most complete and most easily accessible on the southeast coast of Ischia (Fig. 3).

The highest density of landslides is concentrated along the coastline, where mass movements are contributing to the retreat of coastal cliffs, and along inland slopes exposed towards the western directions, where most of the storm systems come from. Temporal information shows peaks of landslides in the years 1986, 1997, and 2005.

The volcanic history of Ischia, southern Italy, has been characterised by alternating periods of intense volcanic activity, resurgence, and quiescence (Orsi et al., 1991, Orsi et al., 1996, de Vita et al., 2006, de Vita et al., 2010) since ca. 150 ka (Gillot et al., 1982, Poli et al., 1987, Vezzoli, 1988).The largest eruption was the 56 ka (Gillot et al., 1982) caldera-forming Monte Epomeo. on April 30 th 2006, on the top of the northern slope of Monte Vezzi, in the Ischia island (South Italy). The type of mechanism occurred during these landslide events is classified as a complex debris slide - debris flow, with an intermediate phase of debris avalanche (De Vita et al., 2007). It appeared very similar to
