A magnitude-6.5 earthquake rocked the area around Wellington, the capital of New Zealand, on Sunday, but no injuries have been reported, officials said.

The temblor was felt as far north as Auckland and in the southern city of Christchurch.

The powerful quake shattered windows in a Wellington building, Radio New Zealand said.

Flights were cancelled at the Wellington airport so that engineers could inspect the facility and aircraft, media reports said.

The U.S. Geological Survey, or USGS, said the earthquake's epicenter was 57 kilometers (35 miles) south-southwest of Wellington at a depth of 14 kilometers (about nine miles).

A magnitude-6.3 earthquake killed nearly 170 people in February 2012 in Christchurch, which is in New Zealand's South Island.

New Zealand is located on one of the tectonic plates in the Pacific Ocean and experiences about 14,000 earthquakes annually, of which between 100 and 150 are strong enough to be felt by humans. EFE
