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 bySupported 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 NetworkIM (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
