Il complesso di gallerie drenanti Chianatelle-Felice-Olivella nel Parco Nazionale del Vesuvio (Napoli)

The Chianatelle-Felice-Olivella drainage galleries complex in the Vesuvius National Park (Naples) The Chianatelle-Felice-Olivella complex, located close to the village of Sant’Anastasia on Mt. Vesuvius, is constituted of 4 drainage galleries, each several tens of meters long, with a total drainage of about 0,1 l/s. Their present structure is due to the hydraulic works made, at the end of the 19th century by the king Ferdinando II of Bourbon, whereas the presence of an underground aquifer in this area had been noticed before the 79 a.C. eruption. The underground complex is not only an important archaeological site, but it is nowadays a part of the monitoring network for the Vesuvius volcanic risk assessment managed by the Istituto Nazionale di Geofisica e Vulcanologia. Some important variation of the geochemical characteristics of the Olivella 1 gallery were recorded in coincidence with the October 11, 1999, earthquake.Published225-2351.2.
