Abstract

Starting with 2002 the National Institute for Earth Physics ( NIEP) has developed its real-time digital seismic networ k. This network consists of 39 broad band and short period stations and two seismic arrays. SeedLink and Antelope TM program packages are used for real-time (RT) data acquisition and exchange. The present network is going to be ex panded in the near future. Thus, in 2008 NIEP will install 40 additional broad band stations in Rom anian territory and 40 strong motions stations in Bucharest, so that at the end of the year NIEP will have 119 digital broad-band seismic stations and short pe riod in real time. The communication from digital seismic stations to the Nationa l Data Center in Bucharest is achieved by 5 providers (GPRS, VPN, satellite communication, ra dio lease line and internet), which assure the back-up communication lines. The power energy for all the se ismic stations and the communic ation systems is supplied by batteries which offer 24 hours of autonomy. The processing centre runs BRTT’s Antelope TM 4.9 data acquisition and processing software on two workstations for real-time processing and post processin g. The Antelope Real-Time System is also providing automatic event detection, arrival picking, even t location and magnitude calculation. It provides graphical display and reporting within near-real-time after a local or regional event occurred. The Romanian Seismic Network is permanently exchanging real–tim e waveform data with IRIS, ORFEUS and different Eur opean countries through internet. In Romania, the magnitude and location of an earthquake are now available within a few minutes after the earthquake occurred. One of the greatest chal lenges in the near future is to provide shaking intensity maps and other ground motion parameters, with in 5 minutes post-event, on the Internet and GIS-based format in order to improve emergency res ponse, public information, preparedness and hazard mitigation.
