The contribution of fluid geochemistry to define the structural patterns of the 2009 L’Aquila seismic source

Authors(s) and Affiliation(s)



Field investigations performed in the epicentral area within the days following the April 6, 2009 L’Aquila earthquake allowed several researchers to detect evidence of coseismic ground rupturing. This has been found along the Paganica Fault and next to minor synthetic and antithetic structures. Although a lot of geo-structural and geophysical investigations have been recently used to characterize these structures, the role of the different fault segments – i.e. as primary or secondary faults – and their geometrical characteristics are still a matter of debate. The results corroborate the power of fluid geochemistry in investigating the structural features of active tectonic structures, being particularly helpful in discerning blind faults. More specifically, these data suggest that the youngest fault splays, as in the case of the San Gregorio fault, may represent preferential sites for degassing. - (NF)
