Yangliu Forest Park: an interesting landslide video from South China
An interesting landslide video has been posted to Youtube, showing a failure that occurred last week in Yangliu Forest Park, a tourist area in Quanzhou, Guangxi, South China. There are various angles on this event. The best video that I have found is on Youtube, which shows two different views of the failure:

The commentary says:
At the scene of the emergency, a landslide occurred in the Yangliu Forest Park in Quanzhou, Guangxi. With a loud noise, the earthwork and trees poured down instantly. The people on the scene screamed and quickly escaped to avoid danger, and road traffic was interrupted. Remind everyone, pay attention to safety.
There is a view from the other end of the landslide too, which appears half way through this video, also on Youtube:

The failure appears to be the result of works on the road. The slope that has failed is a steep cut in deeply weathered rock, as the image below shows:

Dave Petley is the Vice-Chancellor of the University of Hull in the United Kingdom. His blog provides commentary and analysis of landslide events occurring worldwide, including the landslides themselves, latest research, and conferences and meetings.
From the second video (the view from the other end of the landslide), at about the 14 second mark, it almost looks like tension cracks where everyone is standing. That whole experience would be terrifying.
Translational landslide is a mass that slides downward and outward on top of an inclined planar surface (Abbott 2004).
