National Institute for Earth Physics, Magurele-Ilfov, Romania

In February 1977, the Department of Seismology from the Romanian Geophysical and Geological Institute (GGI) together with the Laboratory of Geodynamics of the Romanian Academy formed the Centre of the Earth Physics (CEP). In 1994, after a governmental decision, CEP was transformed in the National Institute for Earth Physics (NIEP). NIEP is coordinated by the Romanian Ministry of Education, Research, Youth and Sport.

National Seismic Network Operation and Maintenance

Mission

Real Time Seismic Network- 52 BB sensors- 45 SP sensors

Strong Motion Stations

- 102 episensors

Romanian Seismic Stations

- Sts2- Cmg3esp- Cmg40t- Cmg3t- Ks2000

- Mark l4c- Mark l22- S13- Ranger- gs21

Seismic and Strong Motion Stations in Bucharest area 

- 23 strong motion stations- 9 real-time seismic stations, installed in the same locations as correspondent strong motion stations (CIOR, BSTR, BTMR, BVCR, INCR, CNCR, BAPR, BUC and BUC1) 

Romanian Seismic Stations

- Medium aperture array, consisting of 10 seismic stations located in boreholes and distributed over a 5 km2 area: 9 elements equipped with short-period (SP) vertical sensors (GS-21) and one station equipped with broad-band (BB) three component sensor (KS 54000)- New elements added: 3 broad-band (BB) sensor at BUR01, BUR02 and BUR05 and one strong motion (episensor) at BUR01- New locations: BUR32 and BUR33 equipped with broad-band (BB) sensors.

BURAR Array

Plostina Observatory

Plostina infrasound

· Consists of a seismic array with 6 elements distributed within an 2.5 km aperture (PLOR1, PLOR2, PLOR3, PLOR4, PLOR5 and PLOR6) and an 6 site infrasound array (IPL2, IPL3, IPL4, IPH4, IPH5 and IPH6)·  In addition, sites 2, 3 and 4 are equipped with electrometers and three-component fluxgate sensors·  The collected data are continuously recorded and real-time transmitted to the Romanian National Data Centre, in Bucharest 

Plostina Array

Data is transmitted trough: - dedicated lines - gprs connections - internet connections

DATA ANALYSIS USING ANTELOPE

Automatic processing- P-wave picking- event association- event localization- computation of magnitude- sending e-mail / SMS alerts

Manual processing- phase picking- event association- computation of magnitude- creation of database- sending reports/ bulletins

SeisC om P 3 provides the follow ing features

- data acquisition- data qua lity control- data recording- real-time da ta exchange- netw ork sta tus monitoring- real-time da ta processing

-issuing event a le rts - waveform archiving- waveform data distribution- automatic event de tection and loca tion- interactive event de tec tion and location- event parameter archiving- easy access to re levant information about sta tions, waveforms and recent earthquakes

DATA ANALYSIS USING SEISCOMP3

Real Time Romania Seismic Network in the framework of Virtual European Broadband Seismic Network (VEBSN) 

Data from all real-time national seismic network stations and from several European stations: VTS (Bulgaria), MORC, VRAC (Czech Republic), APE (Greece), PSZ, PKSM (Hungary), AQU (Italy), KIV (Russia) and ANTO, MALT, ISP (Turkey) are send to the Romania Data Center (RO NDC). 

Data Exchange

RO_NDC Products

- The NDC has developed tools to make information available across the internet.- Acts like a hub between antelope database to mysql database. - Send notification (SMS and email) based on the parameter of an earthquake.
