- Abstract
A long-term (2004-2015) analysis of the fluctuations of Earth’s thermally emitted radiation, measured by the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board the Meteosat Second Generation (MSG) satellite in the thermal infrared (TIR) spectral range (i.e. 10-12 µm), have been performed in order to investigate the complex process of preparation of earthquakes in that area. Such analysis showed that more than 67% of all identified (space-time persistent) anomalies occur in the pre-fixed space-time window around the occurrence time and location of earthquakes (M≥4), with a false positive rate smaller than 33%. Moreover, Molchan error diagram analysis gave a clear indication of non-casualty of such a correlation, in comparison with the random guess function. In this paper, the characterization of the signal, in terms of punctual expected values and related variability, have been extended up to 2022 and the Robust Satellite Technique (RST) and RETIRA (Robust Estimator of TIR Anomalies) index applied to identify possible Significant Sequences of TIR Anomalies (SSTAs) in 2023 in relation with the seismic sequence that hit the region of Kahramanmaraş starting with the February 6th, M7,8 EQ., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)
