This paper investigates earthquake precursors which can be detected from geospatial time series data in synergy with ground monitoring data. Have been analyzed air and land surface temperature anomalies, Aerosol Optical Depth (AOD) variations as well as anomalies recorded by outgoing long-wave radiation and latent heat flux from TIR (Thermal InfraRed) from MODIS Terra/Aqua, NOAA AVHRR, Landsat TM/ETM/OLI and Sentinel 1/ 2 data. Also have been located ground surface deformations detected through Synthetic Aperture Radar Interferometry (InSAR) radar satellite (Sentinel 1) and high quality in-situ GPS monitoring data as well as in-situ monitoring of radon in air near the ground for some moderate earthquakes recorded during 2012 – 2016 period in Vrancea active region in Romania. As Vrancea zone in Carpathians has a significant regional tectonic activity in Romania and Europe, the joint analysis of satellite and field geophysical information is revealing new insights in seismic hazard assessment.
