AB: Space-time fluctuations of Earth's emitted Thermal Infrared (TIR) radiation observed from satellite, months to weeks before earthquakes occurrence, have been, by several authors interpreted as pre-seismic signals. A robust approach (RAT) has been recently proposed (and successfully applied in the field of the monitoring of the major environmental risks) that permits to give a statistically based definition of TIR anomaly also considering the other natural (e.g. due to space-time changes in atmospheric transmittance or surface emissivity and morphology) and observational (time/season, but also solar and satellite zenithal angles) factors that, rather than earthquake occurrence, could be responsible of observed TIR signal fluctuations. In this work the actual potential of satellite TIR surveys for seismically active areas monitoring is evaluated on the base of several years of NOAA/AVHRR and METEOSAT observations over Europe. TIR signal anomalies, possibly associated to earthquakes recently occurred in Europe, have been particularly considered in order to evaluate the robustness of the proposed approach against the possibility of false events detection (specially important for this kind of application) as well as its intrinsic exportability not only on different geographic areas but also on different satellite instrumental packages.
