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.

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 (GS21) 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 infrasound
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
Data is transmitted trough: - dedicated lines
- gprs connections
- internet connections

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.
