Tsunami alerts are your first line of defense in coastal regions. Here’s a breakdown of the four-tiered alert system from the NWS and what each level entails:
Tsunami warning: Immediate action required
This alert is issued when a tsunami that could result in widespread flooding is either expected or already underway. It comes with the potential for dangerous coastal flooding and powerful currents that may persist for hours or even days after the initial wave. Local officials will provide instructions, and evacuation is often recommended, directing individuals to move to higher ground or inland, away from the shoreline.
Tsunami advisory: Exercise caution
A tsunami with potential for strong currents or waves dangerous to those in or very near the water is expected or occurring. There may be flooding of beach and harbor areas. Stay out of the water and away from beaches and waterways. Follow instructions from local officials.
Tsunami watch: Stay prepared
A tsunami watch is triggered when a distant earthquake has occurred, and there is a possibility of a tsunami. People in the affected areas are advised to stay tuned for further updates and be ready to take action if required. While the threat isn’t immediate, preparedness is key.
Tsunami information statement: No immediate threat
This statement is issued when an earthquake has taken place, but there is either no threat or it was so distant that it poses no danger. In most cases, there is no potential for a destructive tsunami.
Remember, official warnings might not always offer ample time to react. Nature can provide early warnings, so if you’re near the coast and experience a significant or prolonged earthquake, witness sudden changes in sea levels, or hear unusual sounds from the ocean, take immediate action to move to higher ground. Your safety is paramount, and being aware of these alerts can be life-saving.
