“…Because of its position, the Aversa plain was reached primarily by volcanic deposits from Campi Flegrei and the Vesuvius, with the most recognized tephra being the Campanian Ignimbrite (dated at 39.28 ± 0.11 ka by De Vivo et al, 2001), the Neapolitan Yellow Tuff (dated at 14.9 ± 0.4 ka by Deino, Orsi, de Vita, & Piochi, 2004) and the Pomici di Avellino (dated at 3550 ± 20 14 C yr BP by Passariello et al, 2009). Both these still active volcanoes strongly affected the recent soil formation processes of the study area (De Vita, Sansivero, Orsi, Marotta, & Piochi, 2010;Orsi, Di Vito, & Isaia, 2004;Santacroce et al, 2008). The Aversa plain was already known throughout the Roman Empire as Campania Felix due to the extreme fertility of its land.…”

The Aversa plain is one of the most important agricultural areas of the Campania region, combining the presence of very fertile soils, sites of great archaeological interest and growing residential urbanization.In this paper, the soil map (1:50,000 scale) of the Aversa plain is presented. Three main land systems (coastal, alluvial and foothill plains) characterized by different soil types (Andosols, Phaeozems, Cambisols, Vertisols, Arenosols, Histosols, Luvisols) have been identified. However, Andosols are the most widespread soil type (9768 ha) and, along with part of the Phaeozems and Cambisols, represent the most fertile soils of the Aversa plain (first and second classes of the land capability classification).In order to evaluate recent intense soil sealing, its impact over land capability classes was assessed during the last 60 years. Results show that soil sealing in the Aversa plain affected mainly the most fertile first-and second-class soils.ARTICLE HISTORY

“…Although these soils originated from volcanic parent material, they do not exhibit andic properties (as defined by IUSS Working Group WRB, 2014), instead displaying vitric properties in a few horizons in P1. Similar to other volcanic soils of the Campania region (di Gennaro and Terribile, 1999;di Gennaro et al, 2002), the chemical and physical properties of Ischia's soils exhibit large spatial variability in both the horizontal and vertical directions among pedons. The main abrupt variation in the soil's properties is identified at variable depths between 70/90 and 205 cm, where pumice-bearing soil horizons (A and Bw) overlie fine ashes (2CB and/or 2C), with the silt content increasing by 20 %.…”

“…Moreover, soil rejuvenation problems could also be verified for sites where volcanological markers are recognised along the soil profiles. Indeed, in the case of MV, where the Piano Liguori formation (5.3-5.8 kyrs BP) was identified at the bottom of the soil, the more recent Cretaio Tephra (first-second century AD) might have arrived in the area (De Vita et al, 2010), rejuvenating the soils. In the case of Sarno and Quindici, the markers of the Vesuvius Pomici di Avellino eruption (dated 3.9 kyrs by Mastrolorenzo et al, 2006), found on the slopes (Di Vito et al, 2008) and along the soil profile (Terribile et al, 2000), could represent a chronological constraint for dating these soils.…”

Volcanic soils and landslides: a case study of the island of Ischia (southern Italy) and its relationship with other Campania events

Abstract. An integrated investigation was carried out on the volcanic soils involved in the landslide phenomena that occurred in 2006 at Mt. Vezzi on the island of Ischia (southern Italy). Chemical (soil pH, organic carbon content, exchangeable cations and cation exchange capacity, electrical conductivity, Na adsorption ratio and Al, Fe and Si forms), physical (particle and pore size distribution, pore structure), hydrological (soil water retention, saturated and unsaturated hydraulic conductivity), mineralogical and micromorphological analyses were carried out for three soil profiles selected in two of the main head scarps.The studied soils showed a substantial abrupt discontinuity in all the studied properties at the interface with a buried fine ash layer (namely, the 2C horizon), that was only marginally involved in the sliding surface of the landslide phenomena. When compared to the overlying horizons, 2C showed (i) fine grey ash that is almost pumice free, with the silt content increasing by 20 %; (ii) k s values 1 order of magnitude lower; (iii) a pore distribution concentrated into small (15-30 µm modal class) pores characterised by a very low percolation threshold (approximately 15-25 µm); (iv) the presence of expandable clay minerals; and (v) increasing Na content in the exchange complex. Most of these properties indicated that 2C was a lower permeability horizon compared to the overlying ones. Nevertheless, it was possible to assume this interface to be an impeding layer to vertical water fluxes only by the identification of a thin (6.5 mm) finely stratified ash layer, on top of 2C, and of the hydromorphic features (e.g. Fe / Mn concretions) within and on top of the layer. Although Mt. Vezzi's soil environment has many properties in common with those of other Campania debris-mudflows (e.g. high gradient, north-facing slope, similar forestry, and volcanic origin of the parent material), the results of this study suggest a more complex relationship between soil properties and landslides and emphasise the role of vertical discontinuities as noteworthy predisposing factors.
