Time series analysis of Land Surface Temperatures in 20 earthquake cases worldwide

DOIAbstract
The objective of the study was to examine if there are detectable localized increases in geostationary satellite-derived Land Surface Temperatures (LST) prior to twenty large (Mw>5.5) and shallow (<35km) land-based earthquakes. Two one-year-long datasets are constructed for every study area: one in a year with earthquakes and one in a year without. LST data are normalized based on the methodology described in Pavlidou et al., 2016. Anomalies are detected when normalized values exceed a threshold. Numbers of anomalies are counted in four spatial zones laying at different distances from the earthquakes and in five temporal periods before, during and after the earthquake. Anomaly densities (number of anomalies per zone and per period) are stat...
