UPDATE: 1:05 p.m. 9/17/15: The Pacific Tsunami Warning Center has issued its final tsunami message for Hawaii saying that based on all available data, the tsunami threat from yesterday’s 8.3 Chile earthquake has now mostly passed. Any remaining threat will be evaluated by local authorities in impacted areas
The Pacific Tsunami Warning Center cancelled the tsunami advisory that was in effect for the state, ending the advisory at 7:33 a.m.
The agency reported the largest wave to be 3.2 feet, occurring shortly after 4 a.m. in Hilo on the Big Island of Hawaii.
In Kahului on Maui a tsunami wave of 1.2 feet was reported at 3:53 a.m.; and a 2.2 foot wave was recorded at 4:35 a.m. according to preliminary data compiled by the Pacific Tsunami Warning Center. Wave activity was occurring in 18 to 22 minute intervals.
Beginning at approximately 3:20 this morning, sea level changes and increased wave heights were observed. Since that time no damages have been reported and conditions have continued to subside and improve, according to Civil Defense authorities.
Authorities say tsunami wave heights across the state are now below advisory levels and are continuing to diminish. The public is reminded that small sea level changes and strong or unusual currents may persist for several additional hours in some coastal areas. Appropriate caution should be exercised by boaters and swimmers when venturing out today.
At 8 a.m., county beach parks were reopened on Maui.
Beach parks were closed in anticipation of impacts from an 8.3 earthquake reported in Chile yesterday afternoon. Several hours later, Hawaii was placed under a Tsunami Advisory. Authorities said that while no major tsunami was expected in the islands, hazardous conditions posed a threat to beach goers and mariners.
The Pacific Tsunami Warning Center was forecasting waves of 1 to 3 feet, and advised the public against entering coastal waters.
The following measurements and reports of tsunami wave activity were documented in Hawaii this morning:

The public is reminded of the following guidelines relating to tsunami activity and compiled by the Pacific Tsunami Warning Center:
* A TSUNAMI IS A SERIES OF WAVES. THE TIME BETWEEN WAVE CRESTS
CAN VARY FROM 5 MINUTES TO AN HOUR. THE HAZARD MAY PERSIST FOR
MANY HOURS OR LONGER AFTER THE INITIAL WAVE.
* IMPACTS CAN VARY SIGNIFICANTLY FROM ONE SECTION OF COAST TO
THE NEXT DUE TO LOCAL BATHYMETRY AND THE SHAPE AND ELEVATION
OF THE SHORELINE.
* IMPACTS CAN ALSO VARY DEPENDING UPON THE STATE OF THE TIDE AT
THE TIME OF THE MAXIMUM TSUNAMI WAVES.
* PERSONS CAUGHT IN THE WATER OF A TSUNAMI MAY DROWN… BE
CRUSHED BY DEBRIS IN THE WATER… OR BE SWEPT OUT TO SEA.
