INSIEME: INduced Seismicity in Italy: Estimation, Monitoring, and sEismic risk mitigation
It has long been known that some human activities are capable of inducing seismicity. The magnitude 6.3, 1967 earthquake occurred in the Koyna-Warna Region in India following the impoundment of a large water reservoir, is the most emblematic case. Other human activities may be responsible for inducing seismicity such as the mining activity, enhanced geothermal systems, the injection/withdrawal of fluids into/from the ground associated with the gas storage, the CO2 sequestration, the exploitation of oil, etc. To date hundreds of worldwide cases of human-induced seismicity have been reported in literature, but this topic is almost unknown in Italy.Even if the basic mechanisms that can induce seismic events related to human activities are presently well understood, models to predict the size and location of earthquakes in response to human perturbations are compromised in large part due to the lack of basic data on the interactions among rock, faults, and fluid as a complex system. Therefore, human-induced seismicity is a pioneering research topic and it represents an open matter of debate within the scientific community, due to the strong social impact and its implications for seismic hazard and risk.Our project is aimed to study the induced seismicity phenomena through the monitoring and modelling of different physical, mechanical and geological parameters involved in the process, as a consequence of perturbations caused by the human activity related to some energy technologies. The research might provide the scientific community with new data to clarify the links among such parameters and the size and location of seismic events. The knowledge of natural and induced seismicity can improve seismic hazard assessment and risk mitigation of the country. The following Italian test sites characterised by different structural-geological setting and human activities are selected for this research project:- the Agri Valley area (Basilicata Region), site of important human activities such as the Eni S.p.A. oil and gas production field and the presence of the Pertusillo water reservoir;- the Collalto area, in the municipality of Susegana (Veneto Region), site exploited by Edison Stoccaggio S.p.A. for the storage of the natural gas.For a deeper understanding of seismicity induced by these sizeable human activities, a dense temporary seismic network with two multi-parametric boreholes and surface seismic stations will be installed in Agri Valley area, and continuous data recoded since November 2008 by a dense network of 10 seismic stations and one permanent GNSS geodetic station in Collalto will be analysed.The recordings of seismic events with dense and technologically advanced seismic networks will be used to compute 3D and 4D (spatial and temporal variation) high-resolution velocity models and to produce multi-parametric models through the integration with electromagnetic methods.The accurate re-locations in 3D/4D velocity models of a large number of small-to-moderate magnitude earthquakes (hopefully with a negative magnitude of completeness), together with geological and geophysical investigations, will provide a powerful tool for:1. defining the detailed geometry of faults in the investigated areas;2. tracking the small-scale variability of faulting style, stress and strength;3. studying seismic source processes and clustering and the space-time evolution of the seismicity;4. understanding interactions among rock, faults, and fluids as a complex system.New statistical methods will be applied to better understand the correlation between the induced seismicity and human activities and to recognize any pattern that can discriminate it from the natural seismicity.The accurate knowledge and characterization of the seismic hazard due to natural and induced seismicity combined with the built environment vulnerability allows for more suitable seismic risk estimation.
