The document discusses the Tridec system used for collaborative decision support during the NEAMWave12 exercise, focusing on tsunami management through advanced real-time information technologies. It highlights the validation of this system through simulated tsunami scenarios involving multiple organizations, including the integration of both conventional seismic sensors and unconventional eyewitness reports for data collection. The findings from the exercise demonstrate the effectiveness of the system in communication and dissemination of tailored warning messages across different platforms.
