Studio preliminare del contesto strutturale dei boati del Fadalto

This study looks in detail at the Lapisina Valley and specifically the residential areas of Fadalto and Farra d’Alpago, which have been subject to rumbling. This area is interesting from a geo-tectonical point of view, as it presents various thrust, in particular the “Longhere-Fadalto-Cadola” line which runs through the area analyzed in my study. Due to these perceived rumbles in the early part of 2011 the OGS (Istituto nazionale di Oceanografia e Geofisica Sperimentale) decided to carry out an! investigation through the use of portable seismometers, which led them to discover relatively shallow microAearthquakes. Furthermore they formulated a hypothesis that these seismic events were responsible for the rumbles!and caused by a phenomenon known!as “Water Hammer”, where a liquid or even a gas is forced to change its natural course and crash into a subterranean rock wall. This thesis is!aimed to define whether these “Water Hammer” events have a structural control. The study is comprised of a detailed geological survey, a structural investigation and a remote-Asensing analysis (Ortho photos). Through accurate fieldwork I was able to draw up a detailed geological map (in:15,000!scale) and a geological profile of the interested area with the use of geographic information system software (ArcGIS); also during this fieldwork I set up three structural stations whose data allowed me to draw rose diagrams.The second part of my study comprised by the telemetric survey of the area allowed me to draw up another rose diagram to compare to the three diagrams previously obtained on the ground. According to this study, there is a possible structural conditioning of mask conduits where water hammer could have accused and on the niche of the Fadalto Landslide
