Modernization of the Modernization of the IM (now IPMA) Seismic - - PowerPoint PPT Presentation

by performing major improvements in the present network: 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

Supported by Supported by

• - Portuguese National Science Foundation, FCT (20 new stations + 6 upgrades)
• - Private Donation (GALP – oil company) (2 new stations)
• - Instituto de Meteorologia, I.P.

Solve some constrains: Solve some constrains:

• - frequency band (SP stations …)
• - dynamic range
• - non real time (digital)

Modernization of the Modernization of the IM (now IPMA) Seismic Network IM (now IPMA) Seismic Network

These improvements allowed: These improvements allowed:

• - 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, shakemaps, etc.)
• - contribute to international monitoring efforts (FDSN, ORFEUS,

tsunami projects [NEAREST, IOC])

• - data for scientific research purposes
