RST Analysis of Anomalous TIR Sequences in Relation with Earthquakes Occurred in Turkey in the Period 2004–2015

The paper provides, for the first time, a long-term (>10 years) analysis of anomalous transients in Earth’s emitted radiation over Turkey and neighbouring regions. RST (Robust Satellite Techniques) approach is used to identify Significant Sequences Thermal Anomalies (SSTAs) about 12 years (May 2004 October 2015) night-time MSG-SEVIRI satellite images. correlation performed with earthquakes M ≥ 4, which occurred investigated period/region within pre-defined space-time volume around SSTA occurrences. It confirms, also Turkey, possibility qualify SSTAs among candidate parameters multi-parametric system time-Dependent Assessment Seismic Hazard (t-DASH). After analysing 4000 images (about 400 million single records), just 155 4 every 100 images) were isolated; 115 (74% out total) resulted earthquake-related (false-positive rate 26%). Results error diagram confirms non-casual between RST-based earthquake occurrences, probability gain values up 2.2 comparison random guess. analysis, separately on Turkish areas characterized by different faults densities, demonstrates dynamic seismicity more than static tectonic settings.
