Several studies have been performed on the basis of anomalous space-time patterns of geophysical parameters measured fromdays to week before earthquakes occurrence. However, even in presence of physical models able to justify the observations (Melbourne et al. , 1997; Revil and Glover, 1997; Pulinets, 2009, Tramutoli et al. , 2013), up to now no one single measurable parameter, no one observational methodology has demonstrated to be sufficiently reliable and effective for the implementation of an operational earthquake prediction system Fig. 1 – In the upper part is shown the portion of the RETIRA computation area scene used in order to calculate the spatial average T(t) used for the computation of the considered signal ΔT( r ,t’) =T( r ,t’)-T(t’) and corresponding reference fields μ ΔT ( r ) (temporal mean) and σ ΔT ( r ) (temporal standard deviation). The red boxes in figure represent the two investigated area respectively the Po plain and Pollino area. In the bottom part two examples of products provided for the two areas are reported, where different colors represent different value of RETIRA index (yellow 3<=RETIRA<3,5; orange 3,5<=RETIRA<4; red RETIRA>=4) and cloudy pixels (gray). 146 GNGTS 2013 S essione 2.1
