Earthquake rattles New Zealand city; no injuries

A magnitude-4.7 earthquake has rattled the quake-weary New Zealand city of Christchurch. There are no initial reports of serious injuries or damage.

Authorities closed down the downtown part of the city after Friday's quake and asked hundreds of construction workers to leave the area as a precaution. Officials say they plan to check buildings over the weekend before allowing the workers back in to continue the job of rebuilding the downtown area, which was devastated by a magnitude-6.1 quake in February 2011 that killed 185 people.

The city has been rocked by hundreds of temblors since then.

The U.S. Geological Survey reported that Friday afternoon's 4.7 quake was centered about 27 kilometers (17 miles) east of Christchurch.
