The Tsunami Warning Bulletin is an essential component of the Tsunami Warning Centre (TWC), dedicated to providing early alerts on potentially destructive tsunamis to emergency officials and, when feasible, directly to the public. Leveraging local and global seismographic networks for real-time monitoring of seismic activities, the bulletin plays a critical role in the internationally-coordinated effort to mitigate the impact of tsunamis across the globe. By rapidly disseminating advisory and warning messages to relevant authorities, the Tsunami Warning Bulletin ensures that communities are prepared, informed, and can take timely action to safeguard lives and properties against the imminent threat of tsunamis.
