Abstract:
Starting with 2002 the National Institute for Earth Physics (NIEP) has developed its real-time digital seismic network. This network consists of 35 broad band and short period stations, two seismic arrays. SeedLink and AntelopeTM program packages are used for real-time (RT) data acquisition and exchange. The present network will be expanded in the near future. In 2008 NIEP will install 40 additional broad band stations in Romanian territory and 40 strong motions stations in Bucharest, so that end of the year NIEP will have 105 digital broad-band seismic stations and short period in real time. The communication from digital seismic stations to the National Data Center in Bucharest is assured by 5 providers (GPRS, VPN, satellite communication, radio lease line and internet), which will assure the back-up communications lines. All the seismic stations and the communication systems are energy supplied from batteries which offer a 24 hours of autonomy. The processing centre runs BRTT’s AntelopeTM 4.9 data acquisition and processing software on 2 workstations for real-time processing and post processing. The Antelope Real-Time System is also providing automatic event detection, arrival picking, event 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 –time waveform data with IRIS, ORFEUS and different European countries through internet. In Romania, magnitude and location of an earthquake are now available within a few minutes after the earthquake occurred. One of the greatest challenges in the near future is to provide shaking intensity maps and other ground motion parameters, within 5 minutes post-event, on the Internet and GIS-based format in order to improve emergency response, public information, preparedness and hazard mitigation.
