The OGS Northeast Italy Virtual Seismic Network
The OGS Northeast Italy Virtual Seismic Network: partners • ARSO, Agenciji Republike Slovenije za Okolje (Agency of the Republic of Slovenia for the Environment), Ljubljana, SLOVENIA • BZ, Provincia di Bolzano (Bolzano District), Bolzano, ITALY • INGV, Istituto Nazionale di Geofisica e Vulcanologia (National Institute for Geophysics and Volcanology), Roma, ITALY • SED, Schweizerische Erdbebendienst (Swiss Seismological Service), Zürich, SWITZERLAND • TN, Provincia di Trento (Trento District), Trento, ITALY • UNITS, Università di Trieste (Trieste University), Trieste, ITALY • ZAMG – CTBT NDC Austria, Zentralanstalt für Meteorologie und Geodynamik (Central Institute for Meteorology and Geodynamics), Wien, AUSTRIA
The OGS Northeast Italy Virtual Seismic Network: partner stations • ARSO, Ljubljana, SLOVENIA: 12 Broad Band (Quanterra Q730 + Guralp CMG40T) • BZ, Bolzano, ITALY: 7 Very Broad Band (Quanterra Q330 + Streckeisen STS-2) • INGV, Roma, ITALY: 12 Broad Band (Nanometrics Trident/INGV GAIA + Nanometrics Trillium 40) • SED, Zürich, SWITZERLAND: 6 Very Broad Band (Nanometrics Trident + Streckeisen STS-2) • TN, Trento, ITALY: 8 Short Period (Solgeo + Lennartz 5 sec) • UNITS, Trieste, ITALY: 4 Very Broad Band (Quanterra Q330 + Streckeisen STS-2) • ZAMG, Wien, AUSTRIA: 11 Very Broad Band (Quanterra Q330 + Streckeisen STS-2)
The OGS Northeast Italy Seismic Network
The OGS Northeast Italy Seismic Network: stations • 17 (Very) Broad Band • Quanterra Q330/Q4128/Q680 • Streckeisen STS-2, Nanometrics Trillium 40/120 sec
• 18 Short Period • Lennartz Mars 88 • Lennartz 3Dlite
The OGS Northeast Italy Seismic Network: station challenges • hardware diversity • mix (Very) Broad Band / Short Period • mix trigger / continuous • accessibility in remote sites (mountain area) • communication availability (GPRS/UMTS, satellite, spread spectrum) • power supply availability (main / solar panels, batteries) • specialization (VBB, SP, data links)
The OGS Northeast Italy Seismic Network: data acquisition
The OGS Northeast Italy Seismic Network: data acquisition challenges • hardware diversity (SUN, Intel, MAC) • OS diversity (SUN OS, Linux SuSe, Linux SlackWare, MAC OS X) • software diversity (Antelope, SeisComP) • HW & OS maintenance: outsorce • SW maintenance: in-house • multiple clients / multiple services • => specialization (task -> responsible)
Northeast Italy seismicity 1977-2011
Improving maintainability: automatic monitoring (with alarms) • Automate State-Of-Healt monitoring: • web • email / Short Message System Alarms • Station hardware • Data links • Waveform data acquisition & archiving • define what to monitor & how (metrics)
