A massive rescue operation continues this Monday to find survivors of a strong quake that struck the densely populated city of Zhaotong in China a day earlier, toppling thousands of buildings and killing over 400 people.
So far, the number of injured stands over 18-hundred, but is expected to rise.
The 6.1 magnitude earthquake had the deepest impact on Ludian, a county of some 449-thousand people located in China's southwestern Zhaotong prefecture.
China's state-run Xinhua News Agency says an estimated 80-thousand homes have been destroyed and 124,000 more seriously damaged.
It is still unknown how many people could STILL be trapped under the debris as rescue teams have yet to reach some remote villages.
A major relief operation is underway, with over 18-thousand rescuers dispatched to the worst-hit areas, carrying tents, food and excavating tools.
The Red Cross Society of China has sent quilts and tents, while Red Cross branches in Hong Kong and Macau are also sending relief supplies.
Chinese authorities scaled up their disaster response to the highest national level in the aftermath of the worst earthquake to hit the region in 14 years.
Chinese President Xi Jinping has ordered authorities to make "all-out efforts" to save lives, while Premier Li Keqiang arrived at the disaster site on Monday afternoon to oversee relief efforts.
The quake struck in a largely agricultural area that is prone to seismic activity.
In 1970, a magnitude 7.7 quake in Yunnan killed at least 15-thousand people.
