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
