Some 780 rescue workers dug through rubble in search of 120 people missing after the landslide buried more than 40 homes in southwestern Sichuan province, the Chinese state-run broadcaster China Central Television (CCTV) reported Saturday.

“Authorities must make maximum efforts to reduce casualties and prevent secondary disasters,” President Xi Jinping said, calling in an official statement for “all-out efforts” to save those who were buried.

Authorities launched the highest level of disaster response, the broadcaster said. Relatives of the missing and those suffering losses in the disaster will be given appropriate care, Xi said.
The landslide occurred at 6 a.m. local time in Xinmo village in Mao County, Aba Prefecture, CCTV said.

A smaller, second landslide caused huge rocks to fall onto the village, which made it more difficult for heavy machinery to get to the scene, police team leader Wang Yongbo told CCTV.

A family of three was pulled alive from the rubble on Saturday, the Mao County government said on its official Weibo page. The couple and their baby were being treated at the Mao County People’s Hospital, the post said.

Qiao Dashuai, whose infant is just 1 month old, said he heard a loud sound and tried to close the door to his house against the wind, he told CCTV.

“I ran outside and felt this strong wind and saw water rushing towards us,” he said. “A rock fell into our living room. We slowly crawled out while holding our baby and escaped. People from a neighboring village gave the baby a bath, and looked for clothes for us and the baby. As we went to the crossroads, we saw an ambulance. The ambulance sent us to Mao County (Hospital).”

“Now we just have external wounds, and there aren’t any major problems. But my heart feels uncomfortable. Several dozen households in this one village have all been submerged,” he said.

The landslide happened at a high part of a mountain and fell onto the village, blocking a 2-kilometer (1.25-mile) section of a river, China’s state-run news agency Xinhua reported.

Landslides’ causes are complicated and could include rain and unstable rock masses, an official from China’s Ministry of Land and Resources told CCTV.

“In this landslide, we feel that it is also because the whole mountain structure in Sichuan has become loosened following the earthquake on May 12, 2008. There is a drop in the ‘dynamic properties’, and its stability has also decreased. The recent rainfall has triggered the landslide,” Tian Yanshan said.

“Earthquakes, mining activities — many man-made and natural activities can possibly trigger landslides. When the stability of the mountain structure has reached its maximum, any triggering factor could lead to landslides,” Tian said.

Mountainous Sichuan province has a history of landslides triggered by flooding and earthquakes. In 1933, 6,800 people died in landslides triggered by an earthquake and 2,500 more were killed when one of the landslides caused a dam to fail.
