Tsunami Preparedness and Procedures
National Weather Service (NWS)
A tsunami watch is issued when a tsunami may later impact the watch area. The watch may be upgraded to a warning or advisory or canceled based on updated information and analysis. Emergency management officials and the public should prepare to take action.
A tsunami advisory is issued when a tsunami with the potential to generate strong currents or waves dangerous to those in or very near the water is imminent, expected, or occurring. The threat may continue for several hours after initial arrival, but significant inundation is not expected for areas under an advisory. Appropriate actions to be taken by local officials may include closing beaches, evacuating harbors and marinas, and the repositioning of ships to deep waters when there is time to safely do so. Advisories may be updated, adjusted geographically, upgraded to a warning, or cancelled based on updated information and analysis.
A tsunami warning is issued when a tsunami with the potential to generate widespread inundation is imminent, expected, or occurring. Warnings alert the public that dangerous coastal flooding accompanied by powerful currents is possible and may continue for several hours after initial arrival. Warnings alert emergency management officials to take action for the entire tsunami hazard zone. Appropriate actions to be taken by local officials may include the evacuation of low-lying coastal areas, and the repositioning of ships to deep waters when there is time to safely do so. Warnings may be updated, adjusted geographically, downgraded, or canceled based on updated information and analysis.
- Monitor an emergency alert system radio station (ex: NOAA 162.55 AM), TV news station, or official news social media accounts for updates.
- If you hear an official tsunami warning or sirens sound, gather your two week kits and prepare to evacuate to higher ground.
- Evacuate at once to high ground. Second level of Hales and TVA apartments are sufficient unless otherwise directed.
- Off-campus students should evacuate to the second floor of the on campus dormitories (hales).
- PCC Guests should evacuate to the Cannon Activities Center. Remember, no food will be provided at the Canon Activity Center shelter.
- Remain in safe area until warning expires or until emergency personnel have issued an “all clear” signal.
