Abstract:
A large scientific documentation is to-date available about the appearance of anomalous space-time patterns of geophysical parameters measured from days to week before earthquakes occurrence. Nevertheless up to now no one measurable parameter, no one observational methodology has demonstrated to be sufficiently reliable and effective for the implementation of an operational earthquake prediction system.

In this context PRE-EARTHQUAKES EU-FP7 project (www.pre-earthquakes.org), investigated to which extent the combined use of different observations/parameters together with the refinement of data analysis methods, can reduce false alarm rates and improve reliability and precision (in the space-time domain) of predictions.

Among the different parameters/methodologies proposed to provide useful information in the earthquake prediction system, since 2001 a statistical approach named RST (Robust Satellite Technique) has been used to identify the space-time fluctuations of Earth’s emitted Thermal Infrared (TIR) radiation observed from satellite in seismically active regions.

In this paper RST-based long‐term analysis of TIR satellite record collected by MSG/SEVIRI over European (Italy and Greece) and by GOES/IMAGER over American (California) regions will be presented. Its enhanced potential, when applied in the framework of time-Dependent Assessment of Seismic Hazard (t-DASH) system continuously integrating independent observations, will be moreover discussed.
