A magnitude 8 earthquake struck Wednesday off Santa Cruz Islands, shortly after a magnitude 6.3 quake struck in the same area, triggering a tsunami warning for islands in the Pacific, U.S. watch centers said.

The magnitude 8 quake occurred at 12:12 p.m. local time (0112 GMT) at a depth of 5 kilometers off Santa Cruz Islands, which are part of the Solomon Islands nation, about 347 kilometers east of Kira Kira, Solomon Islands, the U.S. Geological Survey said.

A tsunami warning was issued for areas in the Pacific including Solomon Islands and Papua New Guinea, while a tsunami watch was in effect for other areas including Marshall Islands and Samoa, the Pacific Tsunami Warning Center said.

Civil Defence still urging caution after tsunami watch cancelled

Swimmers and boaties, including those in Kapiti, are being warned to keep safe ahead of a small tsunami likely to hit New Zealand this evening.

The wave was generated following a magnitude 8.0 earthquake which hit east of the Solomon Islands this afternoon, destroying at least three villages there.

The quake was a shallow 5.8km deep and the epicentre was 347km east of Kira Kira in the Solomon Islands. Several large aftershocks, ranging between 5.2 to 6.6 in magnitude, have hit since the initial quake.

A hospital director told AFP three villages had been destroyed by the quake. However, the full extent of the damage yet unknown.

A tsunami measuring 91 centimetres in height had been recorded at Lata Wharf in Santa Cruz Islands, near the epicentre.

There were early fears for a large tsunami that could affect other countries in the region, however, A "warning" by the Pacific Tsunami warning centre was cancelled just before 5pm.

CIVIL DEFENCE URGING CAUTION IN NEW ZEALAND

However, in New Zealand, authorities are still urging care.

The current assessment by the Ministry of Civil Defence & Emergency Management places New Zealand on a tsunami watch. This is a step below a tsunami alert.

The ministry has issued a potential threat advisory for North Cape, Auckland west, East Cape, Gisborne, Auckland east, New Plymouth and Wellington.

It says those in restricted coastal areas in particular need to be aware of the changing conditions expected around 6pm this evening. The wave would be around 1m high.

Director of Civil Defence John Hamilton, speaking from the bunker at Parliament this afternoon, said there was unlikely to be damage to buildings or property due to the tsunami. He said however, that people near the water, particularly swimmers or those in boats, needed to be cautious.

"You just don't know [what could happen] with these things travelling over a long distance."

"If you're in the water particularly in restricted coastal areas you need to be wary of what might happen."

He said in areas like Tutukaka, in Northland, had experienced surges that had damaged boats and yachts in situations like this before. Likewise, he urged swimmers to be careful.

"I wouldn't want to see people being swept out [to sea].

"This is not insignificant but there is not going to be damage to building and things like that."

@Butrflynet,
Big quake, relatively little tsunami.

It's interesting how the type of quake, as opposed to the magnitude of the quake, contributes more to any resulting Tsunami. I believe the one in 2005 caused the movement of a large portion of the ocean floor, displacing a lot of water. I'm guessing this one didn't displace much.

In order to minimize false alarms (which will dull people's reactions to future warnings), scientists need to include topology displacement into their warning system. That's not going to be easy given the short timeframe they have to work with to generate a reliable warning. Lots of challenges to overcome with tsunami prediction.

SIX bodies, including that of a child, have been found in the sodden wreckage left by a tsunami that smashed into villages in the Solomon Islands.

A government spokesman says the 1.5-metre waves that roared into Santa Cruz Island on Wednesday were too fast to outrun for five elderly villagers and one child.

George Herming said several other people were missing today and strong aftershocks were keeping frightened villagers from returning to the coast.

The tsunami was generated by an 8.0-magnitude earthquake in the South Pacific.

Smaller waves were recorded in Vanuatu and New Caledonia.

Herming said an estimated 100 homes had been damaged or destroyed.

The tsunami flooded the airstrip at the nearest airport, preventing relief workers from reaching the region by air.
Sirens were heard in Fiji as the region-wide tsunami alert was issued, locals said.

"Chaos in the streets of Suva as everyone tries to avoid the tsunami!!'' tweeted Ratu Nemani Tebana from the Fiji capital.

The waves reached as far away as Japan, which was hit by a huge tsunami in March 2011 that killed more than 19,000 people.

Japan's Meteorological Agency reported a 40-centimetre tsunami hitting Hachijo Island about 290 kilometres south of Tokyo, while 20-centimetre waves reached the main islands of Kyushu and Shikoku and smaller waves were recorded on Honshu.

Australian and US monitors said a tsunami wave measuring 91 centimetres washed into the town of Lata, on the main Santa Cruz island of Ndende.

The United Nations Office for the Coordination of Humanitarian Affairs said the wave appeared to have travelled 500 metres inland, inundating Lata's airstrip as well as surrounding villages, flattening many traditional houses.

"We can report five dead and three injured. One of the dead was a male child, three were elderly women and one an elderly man,'' Chris Rogers, a nurse at Lata Hospital, told AFP.

Solomons Prime Minister Gordon Darcy Lilo's office said four villages on the Santa Cruz Islands had been hit by the tsunami.

"Latest reports suggest that between 60 to 70 homes have been damaged by waves crashing into at least four villages on Santa Cruz Islands,'' Lilo's spokesman George Herming told AFP.

"At this stage, authorities are still trying to establish the exact number and extent of damage. Communication to (the) Santa Cruz Islands is difficult due to the remoteness of the islands.''

Solomon Islands Red Cross secretary general Joanne Zoleveke said she had been told at least three villages were hit, with houses washed away.

"In the Solomon Islands when we talk about villages there can be anything from 10 to 30 houses,'' she said.

With Lata's airstrip out of commission, officials were hoping to fly over the area early on Thursday to assess the damage better.
