GLOBAL ONE NEWS — A massive dust storm has hit a province in northwest China.

The “sand wall” engulfed the city of Zhangye in Gansu Province on Sunday, Nov. 25. 

The dust storm was reportedly 100 meters (328 feet) high and moved with a wind speed of up to 40 mph (64 kph).

In just five minutes, it covered apartment buildings and office blocks for an afternoon, according to a witness quoted by Bloomberg. Visibility was less than 10 meters (32 feet), according to The Telegraph.

Dust storms in Gansu and other parts of China are frequent during summer and spring as winds blow dry soil and sand from the Gobi desert to surrounding areas. 

According to The Telegraph, the Chinese government has planted trees in its borders near Gobi desert to prevent dust storms from reaching cities.
