A sandstorm hit Guazhou County in northwest China's Gansu Province on Friday afternoon.
Mobile phone videos showed the height of the wall of sand was over three times that of five-story buildings. The whole county was enveloped by the storm in less than ten minutes.
The storm brought strong gales, with speed of more than 75 kilometers per hour, and dropped visibility to less than 600 meters.
Due to the decreased visibility five vehicles collided on a highway causing a fire and leaving one person injured.
A short rainstorm cleared the skies across the county later.
As the storm moved fast and was over quickly, it did not cause much damage to the local industries or agriculture.
