Wellington: A powerful earthquake struck New Zealand's South Island early Monday, killing at least two people, damaging buildings and infrastructure, and prompting warnings to people along the coast to move to higher ground to avoid possible tsunami waves.
The magnitude 7.8 earthquake struck just after midnight in a mostly rural area that's dotted with small towns. Near the epicenter, it opened up snaking fissures in roads and triggered landslides.
It caused damage in Wellington, the capital, more than 200 kilometres (120 miles) to the north. It was also strongly felt to the south in the city of Christchurch, which was devastated by an earthquake in 2011 that killed 185 people. Residents said the shaking went on for about three minutes, and was followed by a number of strong aftershocks.
Police said one person died in the small coastal town of Kaikoura and another in Mt. Lyford, a nearby ski resort. There were also reports that several people had suffered minor injuries in Kaikoura, police spokeswoman Rachel Purdom said.
The quake completely cut off road access to Kaikoura, said resident Terry Thompson, who added that electricity and most phones were also down in the town of 2,000, a popular destination for tourists taking part in whale-watching expeditions.
Thompson was out of town but managed to reach his wife by cellphone during the night before her phone died.
"She said the glass exploded right out of the double ranch-slider," he said. "The neighbour's chimney was gone, there were breakages and things smashed everywhere."
His wife helped a 93-year-old neighbor and a tourist into her car and drove to higher ground, he said.
"They stayed in the car all night but couldn't sleep," Thompson said. "They're all very, very tired and concerned about the state of their property."
The main road to Kaikoura was blocked in places by landslides, and police were working to airlift out a few tourists stranded in their campervans to the north and south of the town, according to emergency services officials in the nearby Marlborough region.
Kaikoura suffered "major infrastructure" damage in the quake, the Marlborough Emergency Management Group said in a statement. Sewage and water supplies were knocked out, though power was gradually being restored Monday afternoon. Police were in radio communication with the town and mobile phone service was expected to be restored shortly.
Prime Minister John Key was traveling to Kaikoura by helicopter on Monday afternoon. The prime minister said waves of about 2 metres (6.6 feet) hit the coast but the tsunami threat had since been downgraded to coastal warnings.
He said authorities had no reason to believe the death toll would rise above the two reported fatalities.
"On the very best information we have at the moment, we think it's only likely to be two. But of course there are isolated parts of the country which we don't have perfect eyes on, so we can't be 100 percent sure," he said.
Key said officials had decided not to declare a national emergency because the nation's regions were able to adequately cope with the situation.
The quake temporarily knocked out New Zealand's emergency call number, 111, police reported. In Wellington, it collapsed a ferry loading ramp, broke windows and caused items to fall from shelves. It also forced hundreds of tourists onto the streets as hotels were evacuated.
Australians Paul and Sandra Wardrop and their children Alexander, 15, and William, 12, were on the 10th floor of the Park Hotel when the shaking began.
"We felt that the building was going to collapse," Sandra Wardrop said. "You could hear the sounds of the building shaking and see cracks appearing in the walls, in the plasterwork in the bedroom."
The family was among dozens of people who took shelter in the capital's parliamentary complex, which threw open its doors. It was William's 12th birthday, and while he didn't get to tour Wellington as planned, he did get to meet Key, who visited the displaced tourists.
New Zealand, with a population of 4.7 million, sits on the "Ring of Fire," an arc of seismic faults around the Pacific Ocean where earthquakes are common.
Monday's quake brought back memories of the magnitude 6.3 earthquake that struck Christchurch in 2011 and destroyed much of the downtown area. That quake was one of New Zealand's worst disasters, causing an estimated $25 billion in damage.
Monday's quake was stronger but its epicenter was deeper and much farther from major urban areas. Location, depth and other factors beyond magnitude all contribute to the destructive power of an earthquake.
Authorities in Wellington were urging people who work in the city's central business district to stay home on Monday. Officials said some large buildings were showing signs of structural stress, and the quake would likely have caused a mess in some buildings. The city's suburban rail network was shut while crews checked tracks, bridges and tunnels.
New Zealand's Ministry of Civil Defence and Emergency Management reported that a tsunami wave struck at about 1:50 am and warned residents living in low-lying areas anywhere along the country's east coast to move to higher ground.
There was confusion about the tsunami threat throughout the morning. The ministry initially said there was no threat but later wrote on Twitter "situation has changed - tsunami is possible" before reporting that a tsunami had hit.
When the quake hit, Christchurch resident Hannah Gin had just sat down in her living room to watch a replay of the national rugby team's weekend match against Italy when her house started shaking. Upstairs, her mother let out a scream.
The 24-year-old is accustomed to quakes in the temblor-prone region, so she said she sat calmly and waited, figuring the rumbling would stop in a few seconds. Instead, she said by telephone, the shaking went on and on — for at least three minutes, according to the clock on her phone.
The quake was far less violent than the one that struck Christchurch in 2011, Gin said, adding that there was no jarring up and down or side to side, just a long, rolling sensation. But it went on for much longer than the typical quakes that strike the area, she said. She was less concerned about running for cover than she was about vomiting from the motion sickness, she said.
"I could hear the sliding door sliding back and forth, and we've got washing hanging up and I could see the washing moving," Gin said. "It just kept going and going."
The quake was centered 93 kilometers (57 miles) northeast of Christchurch, according to the U.S. Geological Survey. The USGS initially estimated it had a magnitude of 7.4 before revising it to 7.8. It said the quake struck at a depth of 23 kilometers (14 miles), after initially putting the depth at 10 kilometers (six miles). Earthquakes tend to be more strongly felt on the surface when they are shallow.
