History

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.

Mission Seismic Survey of Romania & National Seismic Network Operation and Maintenance Research Tasks

seismic source and seismotectonics seismic hazard assessment site effects and microzonation lithosphere structure and dynamics earthquake prediction assessment and mitigation of seismic risk

National Institute for Earth Physics Romania's Technical Participation to global seismological monitoring in support of Comprehensive Nuclear Test-Ban Treaty (CTBT) Advanced Seismic Data Collection Management System

robust real-time data acquisition techniques reliable communications links rapid processing and exchange of earthquake information creating and handling of large data sets compilation of bulletins and earthquake catalogues

Romanian Seismic Stations Real Time Seismic Network - Sts2 - Cmg3esp - Cmg40t - Cmg3t - Ks2000 - 52 BB sensors - 45 SP sensors - Mark l4c - Mark l22 - S13 - Ranger - gs21 Strong Motion Stations - 102 episensors

Romanian Seismic Stations

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)

BURAR Array - 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.

Plostina Array Plostina Observatory · 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 infrasound

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

Data Exchange 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).

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.
