Brief Communication – ALARM: an innovative protocol of educating on seismic risk perception, and its assessment
Abstract. The effectiveness of risk mitigation also depends on how well-prepared and informed society is about the risk itself. The younger generation plays a key role in the scientific awareness of society, representing both the future of society and a conduit to reach and educate their families. We developed a didactic experience, based on Serious Games, dedicated to seismic risk that was tested and, then, implemented during the whole COVID-19 pandemic. Before the start and at the end of any of these activities, an evaluation phase was carried out to assess the learning experience and the effectiveness of the science communication technique.
Induced seismicity response of hydraulic fracturing: results of a multidisciplinary monitoring at the Wysin site, Poland
Abstract Shale oil and gas exploitation by hydraulic fracturing experienced a strong development worldwide over the last years, accompanied by a substantial increase of related induced seismicity, either consequence of fracturing or wastewater injection. In Europe, unconventional hydrocarbon resources remain underdeveloped and their exploitation controversial. In UK, fracturing operations were stopped after the Mw 2.3 Blackpool induced earthquake; in Poland, operations were halted in 2017 due to adverse oil market conditions. One of the last operated well at Wysin, Poland, was monitored independently in the framework of the EU project SHEER, through a multidisciplinary system including seis…
Crustal Structure of the Seismogenic Volume of the 2010–2014 Pollino (Italy) Seismic Sequence From 3D P- and S-Wave Tomographic Images
A tomographic analysis of Mt. Pollino area (Italy) has been performed using earthquakes recorded in the area during an intense seismic sequence that occurred between 2010 and 2014. 870 local earthquakes with magnitude ranging from 1.8 to 5.0 were selected considering the number of recording stations, the signal quality, and the hypocenter distribution. P- and S-wave arrival times were manually picked and used to compute 3D velocity models through tomographic seismic inversion. The resulting 3D distributions of VP and VS are characterized by high resolution in the central part of the investigated area and from surface to about 10 km below sea level. The aim of the work is to obtain high-qual…
