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. Despite the increasing number of such observations and some claimed success in earthquake prediction a general consensus of the scientific community regarding methods, models and results of such studies is still far from being achieved. Main problems regard data analysis (how distinguish normal from anomalous TIR signal fluctuations?) and interpretation (which statistical significance have the space-time correlation observed/suggested between TIR signal transient and earthquake occurrence?) often done without a convincing validation/confutation approach. On the other hand, several physical models have been proposed that in principle could explain not only such a correlation but also justify the occurrence of other (geochemical, geo-electrical etc.) precursory phenomena. In this context the potential of satellite techniques using Earth's thermally emitted radiation to monitor seismically active areas will be presented considering: a) recent progresses obtained (on several earthquakes occurred in Europe, Africa and America) from the analysis of several years of satellite observations; b) shared knowledge and still open problems; c) actual perspective of research in this field.
