- Abstract
- An integrated approach (chemical, hydrological, mineralogical and micro-tomographic) has been used to
study the soils of the landslides occurred in the Ischia island (Italy) on April 2006. The study has been
carried out on three soil profiles sampled on representative detachment crowns. The main outcome indicates:
(i) presence of volcanic soils, very rich in primary glass, characterised by the presence of poorly ordered
kaolinite in all horizons and expandable clay minerals only in the deepest horizons (CBb and Cb), (ii) high
values of water content near saturation for all soil horizons, (iii) a relevant vertical discontinuity of soil
physical properties. In particular, the deep silty horizon (Cb) retains high amounts of water at low matric
potential and shows the lowest value of saturated hydraulic conductivity than the other horizons. This microtomographic analysis of this deep horizon indicates a very complex intra-aggregate pore space, which seems
an important factor influencing the specific rheological behaviour of this sliding horizon.
In terms of pedogenetic processes, the soils of M. Vezzi northern slope are very different from those
described for other catastrophic landslides of the Campania region (Sarno, Quindici, etc.), but they have in
common the presence, along the soil profile, of marked physical discontinuities surely contributing to the
initiation mechanisms of the landslides. (literal)
