Rescuers are searching for at least 91 missing people a day after a mountain of excavated soil and construction waste buried dozens of buildings when it swept through a Chinese industrial park.
China’s official Xinhua News Agency said the landslide in the southern city of Shenzhen buried or damaged 33 buildings in the industrial park. Shenzhen is a major manufacturing centre in Guangdong province across the border from Hong Kong that makes products used around the world ranging from mobile phones to cars.
The initial landslide sparked an explosion in a section of a natural gas pipeline owned by PetroChina, the country’s top oil and gas producer. By today, the fire was extinguished and a temporary section of pipe was being laid.
Aerial photos on the microblog of the Public Security Ministry’s Firefighting Bureau showed the area awash in a sea of red mud, with several buildings either knocked on their side or collapsed entirely.
Posts on the microblog said mud had thoroughly infused many of the buildings, leaving the “room of survival extremely small.”
Just seven people were rescued overnight and 13 overall were taken to hospital, including three with life-threatening injuries, according to state broadcaster China Central Television, or CCTV.
Mobile phone video of the noon-time Sunday disaster run by CCTV showed the massive wall of debris slamming into the buildings and sending up huge plumes of dust.
Details are beginning to emerge about the cause of the landslide, which authorities say covered an area of 100,000 square metres (one million square feet) with up to six metres (20ft) of mud.
The Ministry of Land and Resources said the debris originated with a steep, man-made mountain of dirt, cement chunks and other waste that had been piled up against a 100-metre (330ft) high hill over the past two years.
Heavy rain in the region had saturated the soil, making it increasingly unstable and ultimately causing it to collapse with massive force.
“The pile was too big, the pile was too steep, leading to instability and collapse,” the ministry said, adding that the original, natural hill remained intact.
The ministry said it had sent more staff to help monitor the situation and guard against a second collapse.
The 33 damaged or collapsed buildings included 14 factories, two office buildings, one cafeteria, three dormitories and 13 sheds or workshops, Shenzhen deputy mayor Liu Qingsheng said.
Nearly 1,500 people were involved in the rescue efforts, aided by 151 cranes, diggers and other equipment, along with rescue dogs and special life-detecting equipment.
CCTV said Chinese president Xi Jinping and premier Li Keqiang issued orders to make rescuing those trapped the top priority.
Xinhua said that as of today, 59 men and 32 women were missing in the landslide.
Li Yikang, the deputy secretary general of the Shenzhen city government, said more than 900 people had been evacuated and moved to local schools and community centres.
Ren Jiguang, the deputy chief of Shenzhen’s public security bureau, said most people had been moved to safety before the landslide hit.
State media carried photos of what looked like at least one five-storey building leaning over and partly crumpled in the industrial park, and a sea of brown soil covering a vast area around it.
The landslide is the fourth major disaster to strike China this year following a deadly New Year’s Day stampede in Shanghai, the capsizing of a cruise ship in the Yangtze River and a massive explosion at a chemicals warehouse in Tianjian on the coast near Beijing.
Human error has been suspected or confirmed in all three previous disasters, pointing to an often callous attitude toward safety in China despite the threat of harsh penalties.
Three decades of headlong economic growth have been catching up with China in terms of safety and damage to the environment.
Many of the country’s major cities suffer from chronic air pollution. A four-day smog red alert continued in Beijing, forcing schools to close, factories to curtail production and half the city’s cars off the roads.
