The toll so far

• The aid effort has focused on China's south western Sichuan province, where 50,000 troops have been deployed.
• The official death toll has climbed to nearly 15,000 - and that is set to rise.
• 14,000 people are still missing and more than 25,000 are still buried under collapsed buildings.
• The worst affected areas are around the quake's epicentre in the mountainous Wenchuan area, where rain and mudslides have hampered the relief effort.
• In Mianyang city up to 10,000 homeless survivors from the rural county of Beichuan have filled a sports stadium.
