The Ultimate Subwoofer - Tornados!

[Philbo King]

Apparently tornados generate 1 to 10 Hz infrasound that can be detected 60 miles away.

You can't hear it, but this sound can reveal that a tornado is on its way

The destructive power of tornadoes is as sudden as it is violent. Now scientists are eavesdropping on twisters to develop new early warning systems and fight warning fatigue.

The real question is localization, can you tell which direction the tornado is coming from!?

I think the idea is to deploy a spaced array of mics and correlate the arrival times of the sound to triangulate the direction of the sound source. At least that's what I got from the article.
