AB: Short-time variations 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.Different data analysis methods have been proposed in order to identify space-time TIR anomalies possibly related to Earthquake occurrence. 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. Still problems exist which are related to data analysis (how distinguish normal from anomalous TIR signal fluctuations?) as well to interpretation (which statistical significance have the space-time correlation observed /suggested between TIR signal transient and earthquake occurrence?). All these aspect will be discussed in order to offer a critical assessment of the potential contribution of TIR satellite techniques for Earthquake active regions monitoring.
