People survey the aftermath of an earthquake in Yaoshan Township in Qiaojia County, southwest China's Yunnan Province, on February 19.

The 4.9-magnitude earthquake injured 10 people, toppled 139 houses and damaged more than 4,200 others.

China is planning to build a national earthquake monitoring and warning system in five years, said the China Earthquake Administration.

A trial program including nearly 100 monitoring stations is being carried out in southeast China's Fujian Province and has proven successful.
