There is NO tsunami threat to Hawaii.

The Pacific Tsunami Warning Center issued an alert at 3:40 a.m. and made the assessment that there was no tsunami for Hawaii at 4:01 a.m.

A tsunami warning was issued for Papua New Guinea and the Solomon Islands due to the earthquake evaluation. The warning was cancelled soon after it was issued.

Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicenter. For those areas – when no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed. Danger to boats and coastal structures can continue for several hours due to rapid currents. As local conditions can cause a wide variation in tsunami wave action the all clear determination must be made by local authorities.

No tsunami threat exists for other coastal areas in the Pacific although some other areas may experience small sea level changes. The tsunami warning is now cancelled for all areas covered by this center.

The region has suffered from a slew of major earthquakes this month.
