PERL: a dataset of geotechnical, geophysical, and hydrogeological parameters for earthquake-induced hazards assessment in Terre del Reno (Emilia-Romagna, Italy)

Abstract

Abstract. In 2012, the Emilia-Romagna region (Italy) was struck by a seismic crisis characterized by two main shocks (ML 5.9 and 5.8) which triggered relevant liquefaction events. Terre del Reno is one of the municipalities that experienced the most extensive liquefaction effects due to its complex geostratigraphic and geomorphological setting. This area is indeed located in a floodplain characterized by lenticular fluvial channel bodies associated with crevasse and levee clay–sand alternations, related to the paleo-Reno River. Therefore, it was chosen as a case study for the PERL project, which aims to define a new integrated methodology to assess the liquefaction susceptibility in complex stratigraphic conditions through a multi-level approach. To this aim, about 1800 geotechnical, geophysical, and hydrogeological investigations from previous studies and new realization surveys were collected and stored in the PERL dataset. This dataset is here publicly disclosed, and some possible applications are reported to highlight its potential.

Evaluation of Open Geotechnical Knowledge in Urban Environments for 3D Modelling of the City of Seville (Spain)

“…This problem displays itself both on the architectural scale through the use of geothermal energies [4], and also in more extensive situations through the creation of Urban Underground Spaces (UUS) that allow the infrastructural use of subsoil [5]. Similarly, an in-depth understanding of this reality is essential for the design of new growth in favourable environments while considering environmental and anthropogenic hazards [4] such as earthquakes [6], landslides [7], and subsidence [8]. Furthermore, this information contributes to the support of preventive conservation strategies that take into account the effects of climate change [9].…”
