Three workers are missing after massive landslides hit eastern China on Tuesday (December 17).

The dramatic video, filmed in the county of Songyang in Zhejiang Province, shows the mountain collapsing, sending a large amount of dust into the air.

A man can be heard saying: "Landslide, landslide, the houses are all buried."

According to reports, the mountain is also a coal mine. Three out of 17 workers are missing. A factory which is around 2000-sqaure-metre was buried.

More than 300 rescuers arrived on-site, four diggers, two drones and life-detection equipment were use to search for the missing people.

The 14 other workers were evacuated safely.
