The number of hydrological (flood, mass movement), meteorological (tropical storm, extratropical storm, convective storm, local storm), climatological (extreme temperature, drought, wildfire) and geophysical (earthquake, tsunami, volcanic activity) events continue to increases in the last decades at global level. According to different research, statistics and databases (UNISDR, EM-DAT) floods are the most frequent in the last decades worldwide and especially in Romania. On the other hand, the probabilistic hazard results for Romania indicate that, in the future, the highest damages will be produced by floods and earthquakes. In this context, it has become necessary to develop an emergency response service. The emergency service, named GEODIM, integrates the GIS geodatabases: roads, rivers, administrative units, land cover/land use, satellite data (optical and synthetic aperture radar), in-situ measurements, in order to support the disaster management. The Earth Observations data offers the capabilities to monitor the disasters at a large scale, being able to identify areas where the events are not in-situ observed or to monitor large vulnerable areas potentially affected by disasters. The paper presents the downstream emergency response service for disaster hazard in Romania, based on Earth Observation data and other geo-information information.
