Seismological Survey of Serbia National seismological network of Serbia 1
Seismological Survey of Serbia consist of two networks: SEISMOLOGICAL NETWORK ACCELERATION NETWORK 2
Spatial distribution of seismological stations on the territory of Serbia 2016 3
SEISMOLOGICAL NETWORK 4
Seismological Survey of Serbia 1893 Started systematic collection of macroseismic data after Svilajinac earthquake 1906 Started construction of special building for the Seismological Institute 1909 Installation of first instruments 1910 First earthquake was recorded 5

SEISMIC NETWORK Total number of stations 21 (average - 1 station on 4.200 km 2 ): VBB 1 (DIVS) BB 8 LP 1 (BARS,DJES,BBLS, FRGS, GRUS, SJES, BOVS,PRVS) (BEO) SP 11 (SELS, SVIS, BORS, ZAPS, TRUS, IVAS, TEKS, KUBS, BOSS, ZAGS, SUBS) 7
SEISMIC NETWORK VBB DIVS - STS-1+Q680 BB BBLS, GRUS, SJES BARS, FRGS, PRVS BOVS, DJES - STS-2+Q330HR - STS-2+Q330 - PBB-200S+Q4120 8
SEISMIC NETWORK LP BEO - SKD+WAVE 24 SP ZAPS - SS-1+WAVE 24 SELS, BORS, TRUS, IVAS, TEKS, KUBS, BOSS, ZAGS, SUBS - SM3+WAVE 24 SVIS - S-5-S+WAVE 24 9
SEISMIC NETWORK All stations have Internet connection in real time with two national centers, Beograd and Divcibare (8 satellite, 7 wireless, 6 ADSL) Automatic location (within 5 min.) 24 hours manual analysis 10

SEISMIC NETWORK Seismological Survey of Serbia Data exchange Established data exchange with countries from region : Austria Bosnia and Hercegovina (Republic of Srpska) Bulgaria Croatia FYR Macedonia Greece Hungary Montenegro Romania Slovakia Slovenia 14
SEISMIC NETWORK 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 e-mails and SMS to Ministry of Interior s Sector for Emergency Management and to media ( local earthquakes M>2.3) 15

ACCELERATION NETWORK 17
ACCELERATION NETWORK Number of accelerographs 47 Number of locations 32 17 real time data transfer Registration of strong earthquakes is basis for estimation of hazard, so that accelerometric network is precondition for adequate decrease of risk 18
Spatial distribution of accelerographs in territory of Serbia 19
ACCELERATION NETWORK Number of Instruments: 5 EpiSensor (MiniSEED format) 39 ETNA (.evt format, MiniSEED format) 3 SSA-2 (.evt format) 20
ACCELERATION NETWORK Analyzed registrations (V2) of acceleration are available on Web page From 2002 up to now SSS have ~360 registrations 21
Planed activities: Increasing number of weak motion stations (2-3 new stations) Substitution of old type SP seismometers Substitution of old type digitizers Increasing number of strong motion instruments Linking all strong motion instruments by Internet with national seismological centers 22
