If this was created by Mother Nature, then someone needs to make peace with her. If HAARP is doing this they need to be stopped. Was this also the time the floods were going on or is this some past event?

Not a big deal, but just to clarify: this is technically a "duststorm", not a sandstorm.

Sandstorms rarely reach higher than 5-6', contain small, heavy, sand granules (typically quartz/silicon and other heavier components that are too heavy to get much higher above the ground than about human-height), are accompanied by very strong winds, can cause significant damage from ablation/abrasion, and are generally localized, covering a much smaller area than:

Dust storms, which can reach a thousand feet or more in altitude, accompanied by slower winds, contain fine particles of dust and silt (such as loess), and are much larger in breadth and scope than sandstorms, often covering hundred or even thousands of square miles.
