GNGTS 2015 - Atti del 34° Convegno Nazionale

GNGTS 2015 S essione 2.1 15 justify such small values due to the symmetric charge distributions supposed to be the sources of the signals. Such symmetry seems to be responsible for the disappearance of electric field variations far from the source, and at the same time justifying the absence of correlations among signals already evidenced in past studies stations (Fidani, 2011b). Finally, a preliminary discussion of earthquake probability occurrence from anomalies with meteorological influence has been introduced above. A definition for the reliability parameter r, which is the ratio of the genuine anomaly numbers to the total ones, has been proposed in terms of CIEN measurements. References Bina A.

It concerns the mid-long term Seismic Hazard Assessment in Italy, namely focusing on two priority areas, the Po Plain and peninsular Southern Italy. The planning and expected activities for the second and ultimate year S2-2014 (https://sites.google.com/site/ingvdpc2014progettos2/ ) are the continuation of S2- 2012 Project, which results are available for the whole scientific community on a twin project’s website (https://sites.google.com/site/ingvdpc2012progettos2/ ). The S2-2014 Project’s advances have been verified during quarterly meetings with the Joint Commission INGV-DPC (Commissione Paritetica INGV-DPC) organized in July and November, 2014, and in March and June, 2015; the mid-term report on activities was released in November 2014. A final report, organized in 3 sections, has been released after the final conference of all the DPC-INGV Seismological Program, held in Bologna on June 4-5, 2015;
