    Description: Abstract
    Description: 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, and is embargoed until three years after the end of the experiments.

    Description: Abstract
    Description: This archive disseminated through the GFZ-Data Service includes both results and information as-sociated to Bindi et al. (2023). In particular, the archive includes a seismic catalogue reporting ener-gy magnitude Me estimated form vertical P-waves recorded at teleseismic distances in the range 20°≤ D ≤ 98°, following Di Giacomo et al (2008, 2010). The catalogue is built considering 6349 earth-quakes included in the GEOFON (Quinteros et al, 2021) catalogue with moment magnitude Mw larger than 5 and occurring after 2011. Tools used to compute the energy magnitude are free available. In particular, we used stream2segment (Zaccarelli, 2018) to download data from IRIS (https://ds.iris.edu/ds) and EIDA (Strollo et al., 2021) repositories, and me-compute [Zaccarelli, 2023) to process waveforms and compute Me. The methodology applied to me-compute is also implemented as add-on for SeicomP (GFZ and Gempa, 2020) in order to allow the real time computation of Me (https://github.com/SeisComP/scmert).

    Description: Version History: 19 February 2024: release of first version 28 March 2024: release of v.1.1 Addition of the complete list of references for the seismic networks analysed with me-compute as described in Bindi et al. (2024, ESSD). The list is provided as additional txt file in the data download section and all references were added to the XML metadata.
