Sandstorms in big cities is a problem in China even though deserts are far away. Sand and dust from construction sites are spread all over the cities with the wind. 

With the Olympic Games in sight the problem has to be solved. A 15-story hotel in the coastal city of Qingdao was demolished on Sunday morning in an environmentally-friendly way.

Guangdong Provincial Hongda Blasting Engineering Company, who carried out the explosion, made use of advanced technologies for the first time to reduce flying debris and lower the shockwave and dust and noise pollution from the process.

The demolition only took five seconds, with the building collapsing within the planned area. It is reported that a higher grade hotel will be built to replace the old one on the same site. Qingdao will host the 2008 Olympics' sailing events.
