Yet Another Quake Hits Christchurch 4.7-magnitude quake rattles NZ city By Rob Quinn, Newser Staff Posted May 25, 2012 12:49 AM CDT 1 comment Comments Today's quake knocked more bricks off the earthquake-damaged Christchurch Cathedral, seen here days after last year's devastating quake. (AP Photo/Mark Baker, File) (Newser) – One of the stronger of the thousands of earthquakes and aftershocks to hit Christchurch since last year's devastating 6.1 quake struck the New Zealand city today. No reports of serious injuries or damage were received after the 4.7 quake, reports the New Zealand Herald. Authorities closed the city's downtown area—now known as the "red zone"—as a precaution. Buildings in the area will be inspected over the weekend before the hundreds of workers rebuilding downtown are allowed back in. More bricks were said to tumble from the damaged Christchurch Cathedral.
