Abstract
During last decade, due to fast progress of thermal infrared (TIR) technology, all weather, high-resolution and highdynamic range of new developed sensors, a large time-series data base is available for seismic anomalies monitoring. As received satellite infrared information is influenced by many types of factors, the main problem for seismic anomalies recognition is to extract useful information associated with tectonic activities and to eliminate the effects of non-tectonic factors. Pre-earthquake spatio-temporal thermal anomalies are controlled by various factors like as earthquake moment magnitude and its focal depth, geological setting, topography and land covers. In this paper, changes before and after the Vrancea earthquakes in the atmospheric parameters have been investigated on the basis of time-series geospatial and field data analysis. The detected changes show a complementary behavior in terms of the various atmospheric parameters, further showing strong evidence of coupling between lithosphere-land surface-atmosphere associated with the Vrancea’s earthquakes. Have been selected the atmospheric earthquake presignals detectable from space: surface latent heat flux (SLHF), and air (AT) surface temperature anomalies, provided by time-series satellite NOAA AVHRR and in-situ monitoring data. For some analyzed earthquakes, starting with ten days up to one week prior to a moderate or strong earthquake a transient thermal infrared rise appeared in SLHF (tens of W/m2) and AT (2-10°) values higher than the normal, function of the magnitude and focal depth, which disappeared after the main shock. The joint analysis of geospatial, geophysical, and geological information is revealing new insights for Vrancea zone seismicity understanding in Romania.
