The 6.0-magnitude quake, with a depth of 41 kilometers (26 miles), struck 75 kilometers (45 miles) west-northwest of the capital, Port Vila.

It was the second day in a row that a powerful earthquake hit the region, following Tuesday’s 7.5-magnitude quake.

No tsunami warning was issued.

Vanuatu is in the South Pacific Ocean, about three-quarters of the way from Hawaii to Australia, and is made of numerous islands.

The Pacific Tsunami Warning Center lifted its warning for Hawaii about two hours after the series of waves hit Hawaiian shores, and later for most of the rest of the Pacific.

"It’s a big relief," said Jenifer Rhoades, the National Weather Service’s tsunami program coordinator. "It was pretty scary. We’re glad it turned out to be an event where there wasn’t tremendous impacts in terms of loss of life."

The cancellation means residents who evacuated could begin returning to their homes. More than 144,000 people lived in the evacuation zone.

The biggest waves were reported at Kahului Bay in Maui, but even there no flooding or damage was reported, said Shelly Ichishita, a spokeswoman for the state Department of Defense Civil Defense Division.

"All the evidence indicated it would be larger," said Barry Hirshorn, a geophysicist at the Tsunami warning center. "This was a very large earthquake in a part of the world that tends to produce very large tsunamis. We need to walk a line between a false alarm and missing something that’s dangerous and could kill people. Since the science is not exact, we chose to err on the side of not killing people by missing something."

A tsunami warning remained in effect for Russia and Japan.

As the tsunami neared Hawaii, triggered by a massive earthquake in Chile, Hilo International Airport on the big island of Hawaii, which is near the southern coast , was closed, and all crews aboard vessels and on the ground in state ports were ordered to evacuate. A warning siren sounded at 6 a.m. local time, alerting residents to tune into their local television and radio stations for instructions.

"We are counting on the public to follow all the instructions of our emergency personnel," said Hawaii Gov. Linda Lingle. "Anyone who is ordering you to evacuate you need to take it seriously. We need you to evacuate in an orderly fashion.

Homeland Security Secretary Janet Napolitano had been briefed and was monitoring developments from Vancouver, where she is leading a U.S. delegation for the Olympics.

Four Hawaii-based U.S. Coast Guard cutters prepared to get underway to ride out the tsunami at sea, and the service planned to reposition aircraft at low-lying Air Station Barbers Point near Honolulu to be able to respond if big waves hit, officials said.

Lingle declared a state of emergency, a step aimed at making needed resources available, including the National Guard. Several water pumping stations that are in low-lying areas were shut down to prevent equipment from being damaged by flooding.

A regional tsunami warning was issued, but withdrawn just over an hour and a half later.

The US Pacific Tsunami Warning Center (PTWC) had said high waves were likely to hit Tonga, Samoa and other islands around the region.

The quake hit at 0618 local time (1818 GMT) at a depth of 10km (6.2 miles).

“It may have been destructive along coastlines of the region near the earthquake epicentre,” the centre said.

There were no immediate indications of any damage or casualties on Tonga’s main island, Tongan police said in the capital, Nuku’alofa.

US monitors advised that some coastal areas of Hawaii could see a rise in sea level and strong currents lasting up to several hours but said no destructive impact was expected.

‘People laughing’

Tonga resident Pesi Fonua told the Associated Press the quake had lasted for “something like 20 seconds” but he had seen no damage.

Police spokesman Niua Kama told the agency residents did not appear to take the warning seriously.

“People are out on the roads, laughing at the warning,” he said.

They were not moving back from the coast despite tsunami warnings, the spokesman added.

Mary Fonua, a resident of the Tongan capital Nuku’alofa, described experiencing “a lot of rattling and shaking”.

“It went on for about 30 seconds, and I went outside and the house was shaking for about another 30 seconds,” she told AFP.

The epicentre is 480km (300 miles) south-east of Fiji’s Ndoi Island and 1,830km (1,140 miles) north-east of Auckland, New Zealand.

The island state of Tonga is a developing tourist destination.

An underwater volcano has erupted close to the Tonga coast, in the South Pacific ocean.

Scientists sailed to inspect the the volcano, which has been shooting smoke, steam and ash into the air near the low-lying twin volcanic islands of Hunga Tonga and Hunga Ha’apai.

Local authorities said coastal villages close to the active volcano were not yet at risk, and that no warnings had been issued.
