Rescuers searched Monday for 85 missing people a day after the collapse of a mountain of excavated soil and construction waste that had been piled up over two years in China’s manufacturing center of Shenzhen.

CCTV’s Li Yang reports from the scene.

Authorities said the landslide buried or damaged 33 buildings in the industrial park in Shenzhen, a city near Hong Kong that makes products used around the world ranging from cellphones to cars.

The landslide on Sunday in Shenzhen City, south China’s Guangdong Province, was captured by a witness on mobile phone video.

Footage of the scene shows mud shooting-up like a fountain from beneath a hill. The mud covered more than 100-thousand square meters of the industrial park. The area was sealed off afterwards as rescuers search for survivors.

The government in China says about 900 people fled before the mud came down.

The mud slide also caused a nearby section of the West-East Gas Pipeline to explode. Power in the region has been cut-off to reduce further risk.

President Xi Jinping and Premier Li Keqiang issued orders to make rescuing those trapped the top priority.

The landslide Sunday covered an area of 380,000 square meters (450,000 square yards) with silt 10 meters (33 feet) deep, authorities said. At least 16 people were hospitalized, including children, the official Xinhua News Agency said.

The Shenzhen government said seven trapped people had been rescued and 85 others remained missing Monday evening. Earlier in the day it had said 91 people were missing and seven rescued, but it gave no explanation for the change in the missing. No deaths had been reported.

The landslide is the fourth major disaster to strike China in a year following a deadly New Year’s Eve stampede in Shanghai, the capsizing of a cruise ship in the Yangtze River and a massive explosion at a chemicals warehouse in Tianjin on the coast near Beijing.
