Close to 100 people from 40 homes are feared buried after a landslide in Maoxian country in China’s Sichuan province on Saturday.
Rescue operation have begun to trace those missing.
Rescuers used ropes to move a massive rock while dozens of others scoured the mountain for survivors.
Bulldozers and heavy diggers were also deployed to remove boulders.
Local police captain Chen Tiebo said the heavy rains that hit the region in recent days had triggered the landslide.
The full extent of the landslide was at yet unclear.
Landslides are a frequent danger in rural and mountainous parts of China, particularly at times of heavy rains and putting thousands of lives in danger.
A part of mountain in the Tibetan and Qiang Autonomous prefecture of Aba had collapsed.
Earlier in January, 12 people were killed during landslide.
More than 70 were killed by a landslide in the southern commercial hub of Shenzhen in December 2015, caused by the improper storage of waste.
