Tsunami Information Centre

National Tsunami Warning Centres (NTWCs)

• Collect, record, and process earthquake data for the rapid initial warning (locate the earthquake, the depth, the magnitude, the origin time)

• Compute the arrival time of the tsunami in the national forecasting points

• Collect, record, and process sea level data for confirming or cancelling the warning Warning Centres strive to be:

• Rapid, by providing warnings as soon as possible after a potential tsunami generation

• Accurate, by issuing warnings for all destructive tsunamis while minimizing false warnings

• Reliable, by making sure they operate continuously, and that their messages are sent and received promptly and understood by the users of the system.
