“…In this study, we try to get around the problem by working on tephra levels embedded within the successions of two boreholes. The two drilled sites are located at different distances from the potential volcanic sources, respectively at the proximal site of Camaldoli della Torre (Di Renzo et al, 2007), on the southern slopes of Somma Vesuvius, and in a medial-distance site in Sarno alluvial plain (Santo et al, 2019). In the frame of the FUTURE research project (PRIN 2017), a multi-methodological approach was carried out making the first attempt to correlate the volcanic products older than the CI embedded within the deposits and tephra markers widely spread in the Mediterranean Sea and intermountain basins of Southern-Central Apennines.…”

“…Further, another significant triggering factor is the ascent of aggressive geogases, such as CO 2 , and mineralized fluids through deep and buried faults, which may increase the carbonate dissolution and modify the texture of the bedrock or the sediment cover [19]. This latter factor can be accounted for in many seismic areas, where the sinkholes are quite widespread and show clustering along the main active faults considering that, within the active fault plane, deep-seated fluids can uprise, thus reaching the ground surface or being trapped in shallow zones [20][21][22][23][24][25][26][27]. Above all in Central-Southern Italy, sinkholes are not a rare phenomenon triggered by earthquakes, so they must be taken carefully into account for a correct seismic hazard evaluation and to mitigate the seismic risk with proper urban planning.…”

Seismic Soil Characterization to Estimate Site Effects Induced by Near-Fault Earthquakes: The Case Study of Pizzoli (Central Italy) during the Mw 6.7 2 February 1703, Earthquake

et al. 2021

Many of the urban settlements in Central Italy are placed nearby active faults and, consequently, the ground motion evaluation and seismic site effects under near-fault earthquakes are noteworthy issues to be investigated. This paper presents the results of site investigations, the seismic site characterization, and the local seismic response for assessing the effects induced by the Mw 6.7 2 February 1703, near-fault earthquake at the Madonna delle Fornaci site (Pizzoli, Central Italy) in which notable ground failure phenomena were observed, as witnessed by several coeval sources. Even though recent papers described these phenomena, the geological characteristics of the site and the failure mechanism have never been assessed through in-situ investigations and numerical modeling. Within a project concerning the assessment of soil liquefaction potential and co-seismic ground failure, deep and shallow continuous core drilling, geophysical investigations and in-hole tests have been carried out. Subsequently, the geotechnical model has been defined and the numerical quantification of the different hypotheses of failure mechanisms has been evaluated. Analyses showed that liquefaction did not occur, and the excess pore water pressure induced by the shaking was not the source of the ground failure. Therefore, it was hypothesized that the sinkhole was likely caused by earthquake-induced gas eruption.

This study describes the development environments of subsidence dolines based on literary data (development environments create favorable conditions for the local denudation of superficial deposit and thus, for the development of depressions). Development environments are the inclination of the bearing surface, the secondary porosity of the bedrock, the characteristics of the cover, water influx into the cover, karstwater and groundwater, melting permafrost, and anthropogenic activity. These may become optimal when controlled by various geological, geomorphological, and climatic factors. Development environments may be qualitative (there is doline development in case of its presence) and quantitative (doline development occurs in case of suitable quantitative values). The development environment groups of subsidence dolines are environment groups independent of water level, environment groups dependent on water level, and anthropogenic environment groups. In the case of an environment group independent of water level, surface morphology, cover characteristics, geomorphic evolution, and water supply are determining, while in case of an environment group dependent of water level, subsurface water level and its fluctuations and the characteristics of rainfalls interrupting dry seasons are crucial. Anthropogenic impacts mainly affect doline development through water balance.
