(Reuters) - An earthquake with a magnitude of 5.3 struck close to the New Zealand city of Christchurch on Saturday, the U.S. Geological Survey reported, but there were no immediate reports of damage or casualties.
The quake was measured only about 14 km (9 miles) northeast of the city. It was another in a series of quakes that have rattled the city since a major earthquake killed almost 200 people there 10 months ago.
