Strong earthquake hits off east coast of New Zealand

A strong earthquake has struck off the east coast of New Zealand, but there were no immediate reports of any injuries or damage.
The US Geological Survey says the magnitude-5.8 temblor struck on Saturday off the east coast of the North Island at a depth of 20 kilometers (12 miles).
New Zealand is prone to earthquakes. In February 2011, a strong quake in Christchurch killed 185 people and destroyed much of the city's downtown area.
