Robust Satellite Techniques (RST) for Seismically Active Areas Monitoring: the Case of 21st May, 2003 Boumerdes/Thenia (Algeria) Earthquake

Detecting seismic IR anomalies in bi-angular Advanced Along-Track Scanning Radiometer data

“…The RST method is based on a preliminary multi-temporal analysis on several years of satellite TIR records, which is devoted to characterize the TIR signal for each pixel of the satellite image processed. This previous study concluded that, anomalous TIR could be identified within TIR data related to an earthquake (Tramutoli et al, 2001Filizzola et al, 2004;Aliano et al, 2007Aliano et al, , 2008Genzano et al, 2009Genzano et al, , 2010Pergola et al, 2010). Each step of the RST method for detecting seismic anomalies using bi-angular Advanced Along-Track Scanning Radiometer data will be explained and detailed in the following.…”

“…Recently, a data analysis technique named the robust satellite data analysis technique (RST) (Tramutoli, 2007) has been proposed for natural and environmental hazards monitoring and mitigation. This technique has already been validated in the case of many earthquakes (Tramutoli et al, 2001Filizzola et al, 2004;Corrado et al, 2005;Aliano et al, 2007Aliano et al, , 2008Genzano et al, 2007Genzano et al, , 2009Genzano et al, , 2010Pergola et al, 2010).…”

Reducing atmospheric noise in RST analysis of TIR satellite radiances for earthquakes prone areas satellite monitoring

“…It has already been successfully applied to monitor major natural and environmental hazards related to: flood risk (Tramutoli et al, 2001a;Lacava et al, 2005Lacava et al, , 2006Lacava et al, , 2010; volcanic activity (Pergola et al, 2001(Pergola et al, , 2004aTramutoli et al, 2001c;Di Bello et al, 2004;Bonfiglio et al, 2005;Marchese et al, 2006;Filizzola et al, 2007); forest fires (Cuomo et al, 2001;Mazzeo et al, 2007), etc. Since its first application to the 1980 Irpinia-Basilicata's earthquake (Di Bello et al, 2004;Tramutoli et al, 2001b), the RST has been applied to seismically active areas while monitoring several other major (M>5) earthquake events: Athens on 7 September 1999 , Izmit on 17 August 1999 , Gujarat on 26 January 2001 , Boumerdes/Thenia on 21 May 2003 , Hector Mine on 16 October 1999 (Aliano et al, 2008a), Umbria -Marche in October 1997 (Aliano et al, 2008b), Mestia Tianeti (Georgia) on 23 October 1992 (Genzano et al, 2009a), and various seismic events (with 4 <M b < 5.5) occurred in Greece and Turkey in May and June 1995-1996(Corrado et al, 2005.…”

A Statistical Analysis of TIR Anomalies extracted by RST in Relation with Earthquake in Sichuan Area with Use of MODIS LST Data

“…Using MODIS LST data, Pergola 20 studied the 6 April 2009 Abruzzo earthquake found that spatially extended and time persistent TIR anomalies (with RETIRA>3) appear in some space-time correlation with earthquakes of different magnitude occurred in Italy in the considered period (15 March-15 April) and since seven days before the Abruzzo main shock (Pergola, Aliano et al, 2010), while Mebrouk studied 21 May 2003 Boumerdes earthquake and detected a thermal anomaly persisting for a week during the month 25 preceding the earthquake (Bellaoui, Hassini et al, 2017). Many researchers also used data of other satellites, Aliano used 8 years of Meteosat TIR observations to analyze 21 May 2003 Boumerdes/Thenia(Algeria) earthquake found that the area of interest was affected by significant positive thermal anomalies (S/N>2.5-3) about one month before the main shock (Aliano, Corrado et al, 2007), and M.Lisi studied 6 April 2009 Abruzzo earthquake with the use of NOAA/AVHRR 30 TIR observations and TIR anomalies were identified in some space-time correlation with Abruzzo earthquake epicenter between 30 March and 1 April (Lisi, Filizzola et al, 2010). Genzano have studied the 2009 Abruzzo with use of different satellite data(5 years of MSG/SEVIRI, 15years of NOAA/AVHRR and 8 years of EOS/MODIS), t no similar results have been observed in confutation (Genzano, Corrado et al, 2010).…”
