CCTV9英语新闻：无人机视频帮助救援工作拍摄的图像

Four drones from the national mapping agency are currently in the quake hit region in Ludian county. In the 24 hours since the disaster, they took hundreds of videos and images of some 60 square kilometres around the epicentre. This is greatly helping 1 rescuers plan ahead, to ensure timely rescue and relief work.

A whole and clear picture of the destruction the disaster has brought. These videos, taken within 24 hours of the quake, show what rescuers were up against.

"Barrier lakes are a huge danger. Other factors that may hamper 2 the rescue efforts are mudslides and traffic jams," Luo Jianjun, deputy director of National Geomatics Center, said.

Water levels in barrier lakes, which were formed by mudslides pouring into rivers, have been rising fast since day one. That has put villages further downstream in danger. Experts are analyzing 3 pictures and videos by comparing them with geological images from last year.

"The water level in this lake has risen by 30 metres in just one day. This is very dangerous. As we can see from this animated 4 video, this is the normal water level. And in this video, it is already three times larger," Luo said.

The images also show at least eight major sites where landslides 5 have occured. All are located on roads leading to the epicenter. As a result, traffic jams have hampered 6 the flow of rescuers and relief materials.

"The yellow ones are serious mudslides. We can see this whole road has been interrupted. It’s quite difficult to clear it. This is a rescue team, which is stuck on the road," Luo said.

Experts have asked people living downstream from the rivers to evacuate 7, since the barrier lakes can burst any time. Meanwhile, these drones will continue with their vital work to prevent any more loss of lives.
