An initial investigation shows that the 33 buildings have been buried or damaged to various degrees - 14 factory buildings, two office buildings, one canteen, three dormitories and 13 low-rise buildings, said Liu Qingsheng, deputy mayor of Shenzhen, at a press conference on Monday. So far, 151 construction vehicles and a large group of rescuers are still battling at the site where the landslide occurred. Experts at the site said it was unlikely there would be more landslides. PetroChina, China's top oil and gas producer, owned the West-to-East natural gas pipeline that exploded as the landslide hit the area. They announced that the 400-meter-long ruptured pipe has been emptied. A temporary pipe will be built on Monday morning.

Chinese President Xi Jinping and Premier Li Keqiang ordered Guangdong authorities to step up rescue operations and evacuate victims to shelters. 2,000 fire-fighters, police, and health workers were mobilized to the rescue effort and 20 emergency first-aid centers were set up.
