The sand wall over a thousand meters crashed into the American city

The giant sandstorm quickly reached the city of Phoenix, reminiscent of the end of the world.

The 1.6-kilometer sandstorm , or haboob, swallowed the city of Phoenix, Arizona, USA, on August 2, causing more than 120,000 people to lose power and some buildings destroyed, according to Mother Nature Network . "It's a huge sandstorm. This is the classic sandstorm in Arizona sweeping across the southeast of the Death Valley," said Jerry Ferguson, a KPHO channel reporter.

The scene when sandstorms approached almost like the end of the world.

Haboob is extremely strong sandstorms that form in thunderstorms, which can quickly turn the entire land into a dark place. The scene when sandstorms approached almost like the end of the world. Haboob is an Arabic word meaning "windy" . The American Meteorological Association (AMS) used the word haboob for the first time in 1972 to compare Arizona dust storms with the common dust storm in Sudan. "Although less frequent than dust storms in Sudan, these storms are also much stronger," the AMS said.

Sandstorms appear when strong winds blow down and spread out from a thunderstorm, swept with dust and sand in arid desert areas like Arizona. The wind creates a sand wall that can spread over a large area within minutes. Some sandstorms can reach a height of up to 3,048m and a speed of 128km / h.

Although often quickly dissipated, sandstorms remain a serious threat, hindering visibility, making you unable to look beyond half a meter. Winds can damage power lines and destroy buildings.
