Rainstorm-induced landslides are a widespread geomorphological hazard that can lead to major emergencies, causing severe damage to life and property. Due to the extent of the areas usually affected by these phenomena (up to thousands of km2) and/or their typical high areal density, in the early stages of the emergency it can be useful to reconstruc...

Numerical simulations of seismic site response require the characterization of the nonlinear behaviour of shallow subsoil. When extensive evaluations are of concern, as in the case of seismic microzonation studies, funding problems prevent from the systematic use of laboratory tests to provide detailed evaluations. For this purpose, 485 shear modul...

In 2012, Italy was struck by a seismic crisis characterized by two main shocks (ML 5.9 and 5.8) and relevant liquefaction events. Terre del Reno (Emilia-Romagna Region) is one of the municipalities that experienced the most extensive liquefaction effects due to its complex geo-stratigraphic and geo-morphological setting. Thus, it was chosen as case...

Earthquake-induced liquefaction phenomena are commonly observed at shallow depths or at the ground surface above Holocene alluvial deposits. Nonetheless, a high-resolution examination of the relationship between surface manifestations and alluvial stratigraphy has been rarely attempted. In this study, we provide a detailed subsurface model from a s...

CO2 degassing generally occurs in volcanic and geothermal areas. CH4 degassing (seepage) is typical of petroleum-prone sedimentary basins. In both cases, gas migration typically occurs along active gas-bearing faults and/or fractured zones. Hybrid systems, where CH4 from sedimentary rocks is transported upward by deep crustal or mantle CO2, are cal...
