The provincial department of land and resources said the landslide was caused by heavy rain. An estimated 18 million cubic meters of earth mass fell some 1,600 meters, engulfing half of Xinmo Village.

Geological experts at the site said the chance of survival for the people buried was really slim.

Only three people from one family were rescued five hours after the landslide struck. They were taken to Maoxian county People's Hospital and none suffered life-threatening injuries. Another three-year-old child of the family remains buried.

Qiao Dashuai, 26-year-old husband of the family, recalled that he and his wife woke up to cries of their one-month-old son at about 5:30 am.

"Just after we changed the diaper for the baby, we heard a big bang outside and the light went out," said Qiao. "We felt that something bad was happening and immediately rushed to the door, but the door was blocked by mud and rocks."

The husband and wife mainly suffered bruises and their one-month-old son was being treated for pneumonia as he inhaled muddy water.

"I arrived at the site at 7:30 am and found that the whole area was buried by the landslide," said He Dajun, a worker with Maoxian county Power Company.

Another 110 people living nearby in another part of the village were being evacuated to a township school on Saturday night, fearing there might be rain and secondary disasters.
