Summary:

At 527 am HST, a 7.9 magnitude earthquake occurred south of Tonga. This prompted the Pacific Tsunami Warning Center to issue a Tsunami Watch for Hawaii. As additional data from buoys and tide gauges in the South Pacific arrived at the Pacific Tsunami Center over the next couple of hours, the indication was that no large, potentially damaging tsunami had been created. Thus at 739 am HST, the Tsunami Watch for Hawaii was cancelled.

Although the risk for a damaging tsunami no longer existed, a small tsunami had been generated by the quake. The tsunami reached Hawaii around noon HST and was recorded by a number of tide gauges across the state maintained by NOAA's National Ocean Service.

Based upon the gauge readings, the tsunami that reached Hawaii was generally one-half to one foot (6 to 12 inches), although local effects in Kahului Harbor resulted in a slight enhancement with the tsunami about 1 1/2 ft high. The only report received at this office was of unusual tidal surge behavior observed at Hanalei Bay, Kauai shortly after 100 pm HST.

Senorpepr, that report of unusual tidal surge at Hanalei Bay, Kauai: did you find data on this? If you can, when you have time, could you post a link or any data on that? Thanks.
