294 GNGTS 2016 S essione 2.1 In this paper, RST approach has been implemented on 11 years (July 2005 – December 2015) of TIR satellite records collected over Japan by the geostationary satellite sensor MTSAT (Multifunctional Transport SATellites). Preliminary results of the correlation analysis performed by applying predefined space- temporal and magnitude constraints, among the appearance of Significant Sequences of TIR Anomalies (SSTAs; Genzano et al., 2015 and Eleftheriou et al., 2016) and earthquakes with magnitude greater than 5 occurred in Japan territory, show that 62% of SSTAs were in an apparent space-time relations with earthquake with a false alarm rate of 38%. Aprobability gain (PG) from 1,5 (for M≥5 earthquakes) up to 3,5 (for M≥6,5 earthquakes) seem already sufficient to qualify SSTAs (identified by RST approach and RETIRA index) among the parameters to be positively considered in the framework of a multi-parametric system for time-Dependent Assessment of Seismic Hazard (t-DASH) for Japan territory.

Potenza, Italy The contemporaneous availabilty of the new version of the Parametric Catalogue of Italian Earthquakes, known as CPTI15, (Rovida et al. , 2016) and the global ISC-GEM catalogue allowed us to develop a non poissonian approach to seismic hazard. The newCPTI15 catalogue seems to be statistically complete since 1300A.D. for magnitudes of 6 or larger. It yields a b value of about 1, if the Tinti and Mulargia (1985) algorithm is applied. The ISC-GEM catalogue is the product of an ongoing effort to retrieve a worldwide catalog as complete as possible since 1900. The cut off magnitude is 5.5. Currently it is statistically complete since 1960 from magnitudes 6 or larger, with about 5000 shallow events. The probability of occurrence of an event above a given magnitude is usually computed through the use of the survival function, that is the probability that inter-event time interval will
