Providing earthquake warning notifications several seconds before dangerous earthquake waves arrive at a target site significantly reduces the property damages and the number of lives lost. Most earthquake early warning systems (EEWS) developed so far are either regional ("network-based) or "on-site" (stand-alone) systems. The recent upgrade of the seismic networks in Romania and Bulgaria with high dynamic range accelerometers allows recording of moderate-to-large magnitude earthquakes at very close epicentral distances (less than 10-20 km). This allows an increase of the early warning lead-time (the time difference between the alert notification time and the arrival time of potentially destructive waves at a given target).The Romania-Bulgaria border region is significantly affected by earthquakes occurred in both territories: on the one hand, produced by the Vrancea seismic source, with intermediate-depth events (3 shocks/century with magnitude greater than 7), and on the other hand, crustal seismicity recorded in the northern part of Bulgaria (Shabla, Dulovo, Gorna Orjahovitza).In this paper we present the rapid early warning system (REWS) for earthquakes that may affect the border areas of Romania and Bulgaria together with the software tools developed that are now used by emergency situations units in both Romania and Bulgaria.
