This work explores three years of geochemical signals recorded by Pieschi station (Southern Italy). The measuring
 station is located in a thermal spring located in the Southern Apennines Chain, one of the most seismically
 active areas of the Mediterranean region. The spring is located close to a geophysical monitoring network installed
 in 2001 by IMAA-CNR. The probe is able to record temperature and water conductivity with a sampling
 rate of 10 min. From November 2001 to February 2005 several anomalous variations of water conductivity were
 recorded. Correlation analysis with selected local earthquakes was carried out to identify events inducing strain
 effects in the investigated area.
