“…, a value that is higher with respect to most thermal springs in Tuscany and comparable with those of the Aronna and Venelle springs (Celati et al, 1990). As expected, Q sp basically constitutes the main water source for the lake, since it is more than one order of magnitude higher than the net amount of rainwater input into the lake (Q r -Q et ).…”

“…The Ca-SO 4 composition of Lake Accesa water closely resembles those shown by thermal springs of Central Italy, which are fed by hydrothermal reservoirs recharged by meteoric water interacting with carbonateevaporite embedding formations (Bencini et al, 1977;Minissale and Duchi, 1988;Celati et al, 1990, Capaccioni et al, 2001Boschetti et al, 2005), including the Aronna spring (Tab. 1) and other mineral water discharges, e.g.…”

“…6) depends on the local structural assessment consisting of NNW and ENE-oriented fault systems. As a result, the total outflow of mineral water from the study area is one of the highest of Tuscany (Celati et al, 1990) and in general of the Tyrrhenian side of central-southern Italy (Minissale, 2004). The occurrence of relatively high saline sublacustrine springs that discharge into CO 2 -rich Lake Accesa and a pronounced thermocline (Fig.…”

“…2), which allow the uprising of subaqueous springs feeding the lake (Negri, 2008). It is worthwhile to mention that the NW-trending fault system is also controlling spring waters (Aronna and Venelle; Bencini et al, 1977;Celati et al, 1990;Fig. 1b), located in correspondence of small karstic depressions north of Lake Accesa, and other sub-circular depressions (Ghirlanda and Schiantapetto, Caramanna et al, 2008) occurring nearby (Fig.…”

Abstract. Since late 2002, a continuous automatic monitoring network (CAMN) was designed, built and installed in Tuscany (Italy), in order to investigate and define the geochemical response of the aquifers to the local seismic activity. The purpose of the investigation was to identify eventual earthquake precursors. The CAMN is constituted by two groups of five measurement stations each. A first group has been installed in the Serchio and Magra graben (Garfagnana and Lunigiana Valleys, Northern Tuscany), while the second one, in the area of Mt. Amiata (Southern Tuscany), an extinct volcano. The measured parameters are: T, pH, Eh, EC, dissolved CO 2 and CH 4 . The results of three years of continuous monitoring can be summarised as follows: i) the monitoring stations made it possible to detect even small variations of the measured parameters, with respect to equivalent commercial devices; ii) acquired data made it possible to identify the groundwater circulation patterns; iii) in most locations, the observed trend of the acquired parameters is consistent with the periodic manual sampling results, and confirms the mixture of different water types that the hydrogeochemical model has determined.The absence of seismic events with a sufficient energy precluded the possibility to locate anomalies, with the only exception of the Equi Terme site, where an increase in the dissolved CO 2 content was observed twelve days before a M=3.7 earthquake occurred at a distance of 3 km north of the monitoring station.The CAMN resulted as being a suitable tool in order to investigate the anomalous variations of the physical, physicochemical and chemical parameters of aquifer systems as earthquake precursors.
