HONOLULU — The Pacific Tsunami Warning Center ended the tsunami advisory for the State of Hawaii. The advisory was cancelled at 7:25 a.m. this morning, after originally being issued at 5:45 p.m. yesterday due to an 8.2 moment magnitude earthquake off the coast of Northern Chile. No damage has been reported, and emergency personnel reported minimal wave activity.
“Mahalo to our local emergency personnel and all those that came together following the Chile earthquake yesterday,” said Doug Mayne, vice director of Civil Defense. “We would also like to extend our sympathy to those affected by the earthquake in Chile and remind our beachgoers, boaters and other ocean users to continue to follow instruction from ocean safety personnel.”
UPDATED: 6 a.m. Wednesday, April 2
At 6 a.m., Hawaii County Civil Defense Director Darryl Oliveira said he saw the water levels along Hilo side rise, but no injuries or property damage have been reported.
“As forecast, the first waves came in about 3:30 a.m. I was down at Puhi Bay in Keaukaha and there was one resident out and about at the same time. We saw a maybe 6-inch change,” Oliveira said.
“I talked to the folks on the (USCG Cutter) Kiska and they said they did see a small surge in Hilo Bay, but it difficult to distinguish tsunami action from the high surf warning,” he said. “In all, we saw a 1 to 2 foot change in and around Hilo.”
“We’ve had the police checking the small boat harbor through the night and they reported nothing that was causing any issues,” he said.
“All good signs for us,” he said.
Oliveira said beaches will remain closed until the tsunami advisory is lifted – likely at or shortly after 8 a.m.
Pacific Tsunami Warning Center reported the first tsunami action at 3:42 a.m.
According to PTWC:
* Hilo recorded a 1.9 foot sea level change in 16 minutes
* Honokohau Harbor recorded a 0.2 foot rise over 12 minutes
* Honuapo recorded 0.1 foot rise over 16 minutes
* Kapoho recorded a 0.4 foot change over 14 minutes
Hawaii remained under a Tsunami Advisory Tuesday evening following an 8.2 magnitude earthquake off the northern coast of Chile.
The quake struck at 1:47 p.m. Tuesday (Hawaii time) and generated tsunami wave action along the western shores of South America and into Central America.
However, scientists based at Honolulu’s Pacific Tsunami Warning Center said at 6 p.m. Tuesday that they do not expect destructive waves to strike Hawaii’s shores.
As of 6 p.m. Tuesday, scientists predict waves between 1-3 feet to begin washing onto Hawaii shores at 3:24 a.m. Wednesday. However, the waves are not expected to cause flooding.
Meanwhile, authorities are cautioning beachgoers to avoid going into the ocean from about 3 a.m. Wednesday until at least 10 a.m.
According to the Pacific Tsunami Warning Center: Although a destructive Tsunami is not expected, sea level changes and strong currents may occur along all coasts and present with hazardous conditions to swimmers, boaters, and persons near the shore and in harbors or marinas. These hazards may continue for several hours.
During a 6 p.m. press conference, Gerard Fryer, Pacific Tsunami Warning Center geophycist, said, “We’re sure the waves are not going to be large enough to cause any flooding. The issue is strictly at the beach.”
Fryer also indicated it is unlikely the advisory would be upgraded to a warning or watch.
“We’re very sure about this,” he said “We have a lot of information now on what this tsunami is doing.”
The tsunami advisory is expected to remain in place until approximately 8 a.m. Wednesday.
Big Island beaches will be closed until 8 a.m. Wednesday.
No evacuations have been ordered.
UPDATE: 8:25 p.m. Tuesday, April 1
TSUNAMI ADVISORY ISSUED FOR STATE OF HAWAII
The Pacific Tsunami Warning Center has issued a Tsunami Advisory for the State of Hawaii effective at 5:45 p.m. HST based on a 8.2 moment magnitude earthquake off the coast of Northern Chile.
A Tsunami Advisory is issued when a tsunami with the potential to generate strong currents or waves dangerous to those in or very near the water is expected or occurring.
The State Emergency Operations Center will remain activated until the Tsunami Advisory is cancelled.
“Throughout this tsunami advisory, we are in close contact with State Civil Defense, local emergency personnel and all state departments,” Gov. Neil Abercrombie said. “With April being Tsunami Awareness Month in Hawaii, this is a timely reminder that we all need to be prepared and have emergency plans and kits ready.”
Sea level changes and strong currents may occur along all coasts and may be a hazard to swimmers and boaters.
County governments will release instructions to beachgoers, boaters and other ocean users.
Streams and canals that feed into the ocean may also be affected by unusual currents.
The estimated time of arrival of the anticipated effects is 3:24 a.m. HST on April 2, 2014.

Tsunami Animation: Northern Chile, 1 April 2014
USGS: How large does an earthquake have to be to cause a tsunami?
Magnitudes below 6.5
Earthquakes of this magnitude are very unlikely to trigger a tsunami.
Magnitudes between 6.5 and 7.5
Earthquakes of this size do not usually produce destructive tsunamis. However, small sea level changes may be observed in the vicinity of the epicenter. Tsunamis capable of producing damage or casualties are rare in this magnitude range but have occurred due to secondary effects such as landslides or submarine slumps.
Magnitudes between 7.6 and 7.8
Earthquakes of this size may produce destructive tsunamis especially near the epicenter; at greater distances small sea level changes may be observed. Tsunamis capable of producing damage at great distances are rare in the magnitude range.
Magnitude 7.9 and greater
Destructive local tsunamis are possible near the epicenter, and significant sea level changes and damage may occur in a broader region.
Note that with a magnitude 9.0 earthquake, the probability of an aftershock with a magnitude exceeding 7.5 is not negligible. To date, the largest aftershock recorded has been magnitude 7.1 that did not produce a damaging tsunami.
