For over 20 years, the National Institute for Earth Physics (NIEP) has operated a real-time seismic network consisting of 18 short-period stations, 14 of them located in the Eastern and Southern Carpathians and telemetered to Bucharest, 4 stations sited in the southwestern part of Romania and telemetered to a regional recording center. NIEP also operates a free-field strong motion network consisting of 39 high-quality digital stations installed jointly with the Collaborative Research Center 461 ‘Strong Earthquakes’ of Karlsruhe University and 21 analog accelerometers for recording the strong and moderate Vrancea earthquakes. One of its stations (Cheia-Muntele Rosu) became in 1994 part of the GEOFON network, and has been recently upgraded by technical support from the Government of Japan and Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) for participating to the CTBTO international monitoring system. Since 2002, a new seismic monitoring station, the Bucovina Seismic Array (BURAR), has been established in the northern part of Romania, in a joint effort of the Air Force Technical Applications Center, USA, and the NIEP.

Key words: Romanian seismic network, telemetery, free-field strong motion network, seismic array, international monitoring system.
