Abstract
Cumulative stress energy in seismic active regions under operating tectonic force manifests various earthquake precursors. For seismic hazard analysis in Vrancea area placed in the Eastern Carpathians, Romania have been selected the earthquake presignals detectable from space: land (LST) and air (AT) surface temperature anomalies, outgoing longwave radiation (OLR) provided by time-series satellite NOAA AVHRR and MODIS (Terra/Aqua) data. This study analyzed the presignal anomalies of geophysical parameters for some strong and medium recorded earthquake events in Vrancea geotectonic active area: 1977, March 4th, Mw = 7.4; May 30ty, 1990, Mw = 7; 1986 August, 30ty, Mw = 7.1; 2004, October 27th, Mw =5.9.
