Awwal 12, 1432, April 16, 2011, SPA -- New Zealand's quake-ravaged second largest city Christchurch suffered further damage as a series of 10 earthquakes rocked the region on Saturday. Reports said power was cut to 20,000 homes, water mains burst flooding suburban streets, goods toppled from store shelves and rocks toppled from cliffs blocking roads, DPA reported. Mayor Bob Parker said one shock put a multi-storey building north of the city centre on a tilt and surrounding roads were closed. The largest of magnitude 5.3 was the biggest since a 6.3 quake devastated the city centre on February 22. It was already severely damaged by a magnitude-7.1 quake in November. There were no reports of injury but residents were urged stay at home until roads are cleared and to limit use of water. Power was restored to all homes after about two hours, Radio New Zealand reported.
