Significant Cases of Preseismic Thermal Infrared Anomalies

From appropriate identification and real‐time integration of independent observations we expect to improve significantly our present capability to assess the seismic hazard in the short term (from weeks to days before an earthquake). One specific observation (e.g. anomaly in one parameter) sometimes can be used as a trigger or as a reference point (in the space and/or time domain) for activating/improving analysis on other independent parameters whose systematic computation otherwise could be computationally very expensive or impossible. In this chapter, we briefly exemplify these advantages, and the utility of the Robust Satellite Technique (RST) approach. The RST data analysis approach has been implemented on daily TIR satellite records collected over three different areas (Italy, Greece, and Turkey) by the geostationary satellite sensor Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board Meteosat Second Generation (MSG) satellite, in order to evaluate its possible contribution to an improved multiparametric system for a time‐dependent assessment of seismic hazard.
