WELLINGTON, NEW ZEALAND (AP) - New Zealand authorities say a powerful earthquake has generated a tsunami, with the first waves hitting the South Island.
In Wellington, 132 miles north of the quake's epicenter, power was knocked out in some places, and some windows smashed and some chimneys collapsed.
There were no immediate reports of any major damage or injuries in Christchurch.
The quake, which struck just after midnight Sunday, was centered 93 kilometers (57 miles) northeast of Christchurch, according to the U.S. Geological Survey. It was at a relatively shallow depth of 10 kilometers (6 miles). Earthquakes tend to be more strongly felt on the surface when they're shallow.
The quake brought back memories of a 2011 earthquake that struck Christchurch, destroying much of the city and killing 185 people. But Monday's quake was much farther away from any major population centers.
New Zealand sits on the "Ring of Fire," an arc of seismic faults around the Pacific Ocean where earthquakes are common.
