Evaluation

Sea level readings indicate a tsunami was generated. Ptwc has received reports of tsunami related fatalities from the solomon islands and from papua new guinea. No tsunami threat exists for other coastal areas in the pacific although some other areas may experience small sea level changes. For all areas the tsunami warning and tsunami watch are cancelled. This will be the final bulletin issued for this event unless additional information becomes available.

The japan meteorological agency may also issue tsunami messages for this event to countries in the northwest pacific and south China sea region. In case of conflicting information the more conservative information should be used for safety.
