This work deals with the evaluation of radon hazard in urban planning. According to the experiences developed in Europe and in the United States, we propose to associate the measurement of soil radon concentration at the minimum depth of 80 cm with the determination of soil gas permeability in order to calculate RP and RI radon indices. The values of these indices allow classifying the radon hazard of a future building site and planning technical actions to reduce and control indoor radon levels. The applic

As it is well-known, the groundwater wells are often incorrectly located, reducing the hydraulic barrier effectiveness. A quick method for delineating the capture curve also for non co-linear geometry of a wells barrier is thus required. Therefore this paper deals with a non linear location of wells, as a solution of this problem developing an analytical-graphical method to design a barrier whose dimensions (particularly the capture zone width near the wells) are fair sized for the containment of pollution

This report compares the results of analyses of seismic amplification for microzonation in two cases: the first one refers to the use of natural accelerograms while the second one to the use of an artificial accelerogram as bedrock outcropping inputs respectively. Realistic soil schemes and different levels of peak ground acceleration (PGA) were considered. The results show only small differences between the values of amplification such as to be negligible compared to the inherent uncertainties related to t

This paper reports the findings from a laboratory study aimed at the physical and mechanical characterisation of sands belonging to recent Tiber river alluvia (level D Auct.) located in historical centre of Rome. The study was conducted in preparation for subsequent analysis of possible seismically-induced effects of permanent deformation and/or liquefaction under the worst expected seismic shaking scenarios. Tests were carried out on a laboratory-reconstituted granular mix, which was considered to be repre

Italy is a country with a high seismicity, which is particularly concentrated along the Apennine Chain. In this area, earthquakes may exceed magnitude 6 on the Richter scale. The study of earthquakes and of their effects on the natural environment may provide a considerable contribution to national policies of defence against earthquakes and mitigation of their risk. This risk, however, is compounded by the fact that Italy has a high population density and a built heritage which is often inadequate to withs

On 20 May 2012, an M5.9 earthquake occurred in the Emilia region (northern Italy). The earthquake triggered significant ground failures owing to extensive liquefaction phenomena. Although the shaking was relatively moderate, an area lying about 17 km from the epicentre was strongly affected by the phenomenon and an exceptional amount of sand and water flowed up from the ground.
The following is an overview of the phenomenon along with preliminary results from seismological and geotechnical analyses.
