Evaluation Watch

  • Sea level readings indicate a TSUNAMI was generated
  • This TSUNAMI can strike coastlines with a wave height greather than 0.5m and/or cause a TSUNAMI run-up greater than 1m
  • This center will continue to monitor sea level gauges nearest the region and report if any additional TSUNAMI wave activity is observed
  • Authorities should take appropriate action in response to this possibility
  • A TSUNAMI is a series of waves and the forst wave MAY not be the largest
  • TSUNAMI wave heights cannot be predicted and can vary significantly along a coast due to local effects
  • The time from one TSUNAMI wave to the next can be five minutes to an hour and the threat can continue for many hours as multiple waves arrive
