With the aim to evaluate the potentiality of the parameter “RST-based satellite TIR anomalies” in a space-time relation with large earthquakes (M>=6) occurred in Japan from 2005 to 2015, we have performed a long-term statistical correlation analysis (see Genzano et al., 2021).
To accomplish this purpose, we use the Robust Satellite Technique (RST; Tramutoli 1998, 2007), and the Robust Estimator TIR Anomalies (RETIRA; Tramutoli et al., 2005) index, to identify Significant Sequences of TIR Anomalies (SSTAs) over 11 years of night-time satellite images acquired by MTSAT satellites over Japan.
By applying empirical spatial-temporal rules, which are established also taking in account the physical models up to now proposed to explain seismic TIR anomalies appearances, the performed long-term correlation analysis put in relief that a non-casual relation exists between satellite TIR anomalies and the occurrence of the earthquakes.
Here, we summarize the achieved results and discuss them in the perspective of a multi-parameter system, which could improve our present knowledge on the earthquake-related processes and increase our capacity to assess the seismic hazard in the medium-short term (months to days).
Moreover, we will discuss the improvements to the RST approach, recently introduced, aimed to minimize the proliferation of the false positives (i.e. TIR anomalies independent to the seismic sources, but due to other causes, e.g. meteorological factors), as well as the exportation of the RST/RETIRA approach/index on the radiances collected by the next-generation satellite sensor Himawari-8/AHI.
