1 Seismic monitoring in Serbia Seismological Survey of Serbia

2 Seismological Survey of Serbia consist of two networks: SEISMIC NETWORK ACCELERATION NETWORK

3 Seismological Survey of Serbia Spatial distribution of seismological instrument in territory of Serbia (Mart 2013)

4 Seismological Survey of Serbia SEISMIC NETWORK

5 Seismological Survey of Serbia Systematic collecting of data started after Svilajinac earthquake 1893 Construction of special building for the Seismological Institute started in 1906 First instruments where installed in 1909 First earthquake was recorded in 1910

6 Seismological Survey of Serbia SEISMIC NETWORK Total number of stations 22 (average - 1 station on km 2 ): VBB – 1 (DIVS) BB – 6 (BARS, BBLS, FRGS, GRUS, SJES, BOVS) LP – 2 (BEO, DJES) SP – 13 (SELS, SVIS, BORS, ZAPS, KMIS, TRUS, IVAS, TEKS, KUBS, BOSS, KOVS, ZAGS, SUBS)

7 Seismological Survey of Serbia SEISMIC NETWORK VBB DIVS - STS-1+Q680 BB BBLS, GRUS, SJES- STS-2+Q330HR BARS, FRGS - STS-2+Q330 BOVS - PBB-200S+Q4120

8 Seismological Survey of Serbia SEISMIC NETWORK LP BEO, - SKD+WAVE 24 DJES - SKD+Q4120 SP ZAPS - SS-1+WAVE 24 SELS, BORS, TRUS, IVAS, TEKS, KUBS, BOSS, KOVS, ZAGS, SUBS - SM3+WAVE 24 SVIS- S-5-S+WAVE 24

9 Seismological Survey of Serbia SEISMIC NETWORK All stations have Internet connection in real time with two national centers, Beograd and Divcibare (7 satellite, 6 wireless, 11 ADSL) Automatic location (within 5 min.) 24 hours manual analysis

10 Seismological Survey of Serbia Internet presentation SEISMIC NETWORK

11 Seismological Survey of Serbia Acquisition software Seiscomp ver. 2.1 and Seiscomp ver. 3 Analyzing software Seismic Handler Automatic location software Seiscomp 3 SEISMIC NETWORK

12 Seismological Survey of Serbia

13 Seismological Survey of Serbia Data exchange Established data exchange with countries from region : Austria Bosnia and Hercegovina (Republic of Srpska) Bulgaria Croatia Macedonia Greece Hungary Montenegro Romania Slovakia Slovenia SEISMIC NETWORK

14 Seismological Survey of Serbia Publication of data Publishing data on Survey’s internet presentation: Sending automatic alerts to EMSC (M>2.3 for region and M>5.0 for world earthquakes up to distance 103 o ) Sending automatic s and SMS to Ministry of Interior’s Sector for Emergency Management and to media ( local earthquakes M>2.3) SEISMIC NETWORK

15 Seismological Survey of Serbia ACCELERATION NETWORK

16 Seismological Survey of Serbia ACCELERATION NETWORK Number of accelerographs – 47 Number of locations – real time data transfer

17 Seismological Survey of Serbia ACCELERATION NETWORK Number of Instruments from former Project (BSHAP) is :12 ETNA accelerographs

18 Seismological Survey of Serbia Distribution of accelerographs in territory of Serbia.

19 Seismological Survey of Serbia ACCELERATION NETWORK Number of Instruments: 5 EpiSensor (MiniSEED format) 39 ETNA (.evt format, MiniSEED format) 3 SSA-2 (.evt format)

20 Seismological Survey of Serbia ACCELERATION NETWORK Analyzed registrations (V2) of acceleration of stronger earthquakes are available on Web page From 2002 up to now SSS have analized more then 400 registrations

21 Seismological Survey of Serbia ACCELERATION NETWORK We have to prepare significant number of analog registration from Kopaonik region From 2011 SSS have 4 EpiSensors connected to Quantera digitizers, so there will be lot of small (and big) earthquakes registrated (planed to be done for next 6 months)
