Members of the Police DVI (disaster victim identification) team prepare to move a body found in the rubble of the PGC building during ongoing search operations in the aftermath of the earthquake in Christchurch on March 3, 2011. Rescuers have conceded they do not expect to find any more survivors, turning attention to questions about why the damage inflicted on the city in the 6.3-magnitude tremor was so severe. Up to a third of the downtown area faces demolition and two office blocks concertinaed in the violent 15-second shake and were completely destroyed.One of them, the Canterbury Television (CTV) building, housed an English language school attended by Asian students, predominantly from Japan and China, more than 60 of whom are presumed dead in its ruins.
