Tsunami Follows Powerful Quake In New Zealand

A magnitude-7.8 earthquake struck near Christchurch, New Zealand, leading to tsunami activity, officials said Sunday. 

The quake caused damage to buildings and prompted emergency services to warn people along the coast to move to higher ground to avoid tsunami waves.

The scope of damage and size of the tsunami waves are not yet clear. The first tsunami wave struck several hours after the temblor.

The Pacific Tsunami Warning Center issued a delayed tsunami warning after the earthquake, asking people in coastal areas of New Zealand’s South Island to move inland.

The New Zealand Civil Defence Ministry warned that the first tusnami waves may not be the worst, and that tsunami activity could continue for several hours.

The quake knocked out New Zealand’s emergency call number, 111, for about 10 minutes, police reported. It caused items to fall from shelves and windows to break in Wellington, and forced hundreds of tourists onto the streets as hotels were evacuated.

New Zealand’s Ministry of Civil Defence and Emergency Management reported that a tsunami wave struck at about 1:50 a.m.

The magnitude-7.8 quake struck just after midnight Sunday and was centered 57 miles northeast of Christchurch, according to the U.S. Geological Survey. It was at a relatively shallow depth of 6 miles. 

Earthquakes tend to be more strongly felt on the surface when they’re shallow.

As Monday’s quake hit, Christchurch resident Hannah Gin had just sat down in her living room to watch a replay of this weekend’s All Blacks versus Italy rugby match when her house started shaking. Upstairs, her mother let out a scream. 

Gin, a 24-year-old lifelong Christchurch resident, is accustomed to quakes, so she said she sat calmly and waited, figuring the rumbling would stop in a few seconds. Instead, the shaking just went on and on - for at least three minutes, according to the clock on her phone, she said by phone. 

The quake was far less violent than the one that struck her city 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 with a chuckle. 

“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.” 

Her house, which was damaged in the 2011 quake, did not appear to have sustained any new damage from Monday’s quake, she said. She said she had heard from many of her friends who live in the city, and all were safe. 

“As far as I know, everyone’s fine,” she said. “We’re all just really shaken.” 

New Zealand is part of a geologically active region that’s often called the Pacific “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin.

A 2011 earthquake in the city of Christchurch destroyed much of the downtown and killed 185 people.

In 2014, a magnitude-6.7 earthquake struck off the New Zealand coast and rattled much of the country but resulted in few damages or injuries.
