Romanian Seismic Network Since 1980 to the Present

National Institute for Earth Physics is responsible for seismic monitoring of Romania. For this purpose, a dense seismic network is now operating covering almost the entire surface of the country. At present, the Real Time Seismic Network consists of 96 sites with seismic digital equipment, of which 3 in Republic of Moldova, and two seismic arrays: Bucovina (BURAR) and Plostina (PLOR). BURAR array is a high performance seismic monitoring system consisting of 3 broad-band and 9 short period stations distributed over a 5 km\(^{2}\) area. Plostina seismo-acoustic array has been recently deployed in the Vrancea epicentral area for monitoring local microseismic activity and infrasound sources. All the stations are sending data in real time to the National Data Center (NDC) in Magurele. A strong motion network of 120 stations, equipped with accelerometer (EpiSensor—2g full scale) sensors was installed to record strong ground motion. 101 stations are sending data in real-time and 19 are offline stations. Most of the accelerometers are co-located with the seismic sensors. 23 of the accelerometers are operating in Bucharest city. Recently, 32 seismic stations were installed along the Danube River in the framework of the DACEA cross-border project. The goal of this network is to set an Early Warning System for the earthquakes in Romania and Bulgaria which affect the targeted area. To measure the ground motion deformation, a GPS network was developed mainly in the last years. NDC is exchanging data with other national and international seismological centers.
