Description:
The goal of MATISSE is to develop and implement technologies needed for successfully detecting and quantifying hazards connected with geo-energy operations in the sub-surface, in particular induced seismicity. Anthropogenic earthquakes constitute one of the major environmental impacts associated with geo-resources exploitation. Injection induced events are an undesired dynamic rockmass response to technological processes. Water injection operations taking place during industrial activities such as oil, gas and geothermal exploitation often induce microseismic activity and, under specific circumstances, reactivate existing faults, causing events of considerable size. These industrial activities can also determine air pollution and ground water contamination.Induced seismic hazard is evaluated through the computation and update of ground motion prediction equations, the time-lapse of velocity, attenuation and seismic noise tomography and the computation of pore pressure time variations. All these parameters are correlated with operational activities. A multi-hazard approach aimed at evaluating the adverse effects on environment caused by the sub-surface exploitation of geo-resources is developed.This work has been supported by PRIN-2017 MATISSE project, No 20177EPPN2, funded by Italian Ministry of Education and Research.
