| This paper presents a validation and confutation analysis using the methods
of the robust satellite data analysis technique (RST) to detect seismic
anomalies within the bi-angular Advanced Along-Track Scanning Radiometer
(AATSR) data based on spatial/temporal continuity analysis. The
distinguishing feature of our method is that we carried out a comparative
analysis of seismic anomalies from bi-directional observation, which could
help understanding seismic thermal infrared (TIR) anomalies. The proposed
method has been applied to analyse bi-angular AATSR gridded brightness
temperature data with longitude from 5 to 25° E and
latitude from 35 to 50° N associated with the earthquake
that occurred in Abruzzo, Italy, on 6 April 2009, and a full data set of 7 yr
data from 2003 to 2009 during the months of March and April has been analysed
for validation purposes. Unperturbed periods (March–April 2008) have been
considered for confutation analysis. Combining with the tectonic explanation
of spatial and temporal continuity of the abnormal phenomena, along with the
analysed results, a number of anomalies could be associated with possible
seismic activities, which follow the same time and space. Therefore, we
conclude that the anomalies observed from 29 March 2009 to 5 April 2009,
about eight days before the Abruzzo earthquake, could be earthquake anomalies. |
