EVALUATION

A major earthquake has generated a tsunami that could be destructive to coasts in <country>.  The earliest estimated time that the first impacts may occur is <earliest ETA for your country from the PTWC bulletin, converted to local time>.  Authorities should take appropriate action to save lives and reduce property damage for this threat.

TSUNAMI THREAT FORECAST

< copy PTWC sections applicable to a country’s coastal tsunami amplitude wave forecasts in meters above the tide level. >

ESTIMATED TIMES OF ARRIVAL

Estimated times of arrival (ETA) of the initial tsunami wave for points within threatened regions are given below.  Actual arrival times may differ and the initial wave may not be the largest.

RECOMMENDED ACTIONS

•    This message is intended to trigger appropriate actions by <agencies responsible for carrying out evacuations, etc.> in accordance with their tsunami warning standard operating procedures.
•    Persons located in or near threatened coasts should stay alert for instructions from national and local authorities.

POTENTIAL IMPACTS

•    A tsunami is a series of waves and the time between wave crests can vary between five minutes to one hour.  The hazard may persist for many hours after initial wave arrival.
•    The first wave may not be the largest.
•    A coastal tsunami of only 1-meter amplitude above tide level can cause strong currents in a harbor, be dangerous to swimmers in the water and be hazardous to persons along inland waterways.
•    Flooding impacts can vary significantly from one section of coast to the next due to local bathymetry and the shape and elevation of the shoreline.

TSUNAMI OBSERVATIONS

The following are tsunami wave observations from coastal and/or deep-ocean sea level gauges at the indicated locations.  The maximum tsunami amplitude is measured with respect to normal tide level.
