More than 70, 000 people had died in the province in an earthquake in 2008.
The worst hit area of Saturday’s quake was the Lushan county of Sichuan province where buildings crumbled into stacks of debris as tremors continued for nearly 20 seconds.
Thousands were left without homes and rescue workers had put up makeshift shelters to house survivors. Several medical teams were working around the clock to treat the injured.

State media reported that the drone images will cover the hardest-hit Baoxing, Taiping and Longmen townships.
The administration has already obtained satellite images of pre-disaster Lushan county, of Ya'an City in Sichuan Province, through the Ziyuan III satellite.
Helicopters from army installations were also pressed into service to aid rescue work.
