East Pollino Experiment, Southern Italy

The aim of this temporary experiment is to monitor the interaction between crustal fluids and earthquake occurrence. Two sites have been initially investigated: one is in the eastern sector of the Pollino mountain range, located at the border of Southern Apennines chain and Calabrian arc and the other is Mefite d'Ansanto moffete, one of the largest non-volcanic CO_2 emission in the world and located in Irpinia area, in the southern Apennines.
The seismicity in the eastern sector of the Pollino range is very low except for a deep (>20km) earthquake swarm which started in the middle of September 2017 and lasted for some weeks with events up to Ml=2.7.
The Mefite d'Ansanto site sits at the northern end of the northern fault activated by the M_w 6.8 Irpinia earthquake in 1980 and in the well-known thermal anomaly area of the Mt. Forcuso.
A ~10km radius area around Mefite steems out for a very low seismicity rate compared with the high seismicity activity of this portion of Southern Apennines.
In the frame of a long-term collaborative efforts made by the German Research Centre for Geoscience (GFZ) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in the Pollino area a temporary network has been deployed to analyze the low earthquakes rate, the seismogenic structures and a possible signature of interaction with fluids redistribution within the crust.
The temporary network consists of 3 seismic stations equipped with Trillium compact 120 sec. sensors and DCube digitizers using also CCube modules for real time data transmission.
One single station with similar hardware has been used also to monitor the Mefite d'Ansanto in the Irpinia area with similar aim.
Data is available from the GEOFON data centre, under network code YZ.
