  1. Instituto de Meteorologia, I.P. Department of Seismic and Geophysical Monitoring NEAREST 1st Meeting, Bologna, October 2006

  2. Instituto de Meteorologia, I.P. • 1947 – Serviço Nacional de Meteorologia;1977 – Instituto Nacional de Meteorologia e Geofísica; 1993 – Instituto de Meteorologia; 2003 – Instituto de Meteorologia, I.P. • National responsable for the activities in • Meteorology • Seismology • Geomagnetism

  3. Instituto de Meteorologia, I.P. • Atributions: • Maintain and develop the national information systems of meteorology and seismology • Exclusivity in the dissemination of bad weather warnings • Promote contacts with Civil Defense in case of seismic or meteorologic catastrophes • Promote the development of the international relations and cooperation in the domains of meteorology and seismology

  4. Instituto de Meteorologia, I.P. • Department of Seismic and Geophysics Monitoring: • National responsible for monitoring the seismicity in mainland, Madeira islands and adjacente areas • Gives support to the seismic monitoring in Azores, which is performed by the SIVISA consortium (IM and University of Azores) • Runs several seismic networks in the mentioned regions • Portable network • Research work on seismicity, seismotectonics, seismic attenuation and experimental seismology

  5. Published data (1961-2004) 1997-2004

  6. FMP Seismicity 1996-1999 (errZ(90%)<10km

  7. Contribution to the NEAREST project • Portuguese National Seismic network • New broadband and RT network under installation (MODSISNAC) • Seismic monitoring and surveillance experience

  8. Mainland/Madeira Network [IMP]

  9. MODSISNAC – new BB seismic network • Supported by • Portuguese National Science Foundation, FCT (20 stations) • Private Donation (GALP – oil company) (2 stations) • Instituto de Meteorologia, I.P. (operation and maintenance) • Solve some constrains: • frequency band (SP stations …) • dynamic range • non real time (digital) • by performing major improvements in the present network: • introduce significant enhancements in the remote stations • adopt (near) real-time transmission of signals • real-time processing capability

  10. MODSISNAC – new BB seismic network • These improvements will permit: • quality data acquisition in highly sensitive stations which are also equipped with strong-motion sensors • higher quality digital transmission • real time monitoring at the Operational Center • automatic signal detection • automatic association of detections, event location and magnitude evaluation • development of a rapid earthquake information system for Civilian Protection authorities • automatic archive of recorded data • development of high-level products (bulletins, shake maps, etc.) • contribute to international monitoring efforts (FDSN, ORFEUS, tsunami projects [NEAREST, IOC]) • data for scientific research purposes

  11. MODSISNAC – new BB seismic network 21 stations 1 station Seismometer STS-2 Accelerometer Episensor Digitiser Q330 (6 components) (GPS time signal) Seiscomp unit (seiscomp software) Seismometer CMG-3T & 3ESP compact Accelerometer CMG-5T Digitiser DM24 (6 components) (GPS time signal) Seiscomp unit (seiscomp software) VSAT / Internet (seedlink) Data Center (Lisbon) (SEISCOMP) Quality Control Archieve (Storage Area Network) Near RT processing Manual revision

  12. Planned Existing RT(IRIS/IDA, GEOFON, IST, CGUL) MODSISNAC - New BB Seismic Network Portugal mainland Azores isl. Madeira isl.

  13. Expectations • Identification and characterization of the tsunamigenic sources; impact scenarios in SW Portugal • Long-term seafloor observatory with RT access • EWS Prototype

  14. <90º 90º-180º 180º-270º >270º Seismicity 1970-2000
