On August 10, 2020, a fire broke out in northwest Los Angeles County. This by itself cannot be considered news; not even curious. The Californian summer, following what is already a sinister traditionhas become synonymous with huge, wild forest fires.

The curious thing is that, around 4:00 in the afternoon, a fire tornado arose.

Another fire in California. The fire, declared near Gorman (California), reached about 75 hectares and was not too damaging: no human life was claimed, there was no material damage, and it did not originate in an area of ​​special natural interest. That did not prevent a team from KTLA-TV Channel 5 approached the area and his cameras captured something as fascinating as it was terrifying… but allow me not to describe it, allow me to show it to you.

What is a ‘fire tornado’? Fire tornadoes are a very rare phenomenon. So rare that, although they have been occurring throughout history, we were only able to document them in 2003, in the infamous canberra fire. Then we have been finding them with a dropper, yes; but it is not easy for the circumstances of temperature, fuel and air currents to occur, so that the fire acquires a vertical vorticity and forms a whirlpool similar to what we all know as a tornado.

but it happens. It’s not easy, no; but it happens. Although these phenomena are believed to have occurred in some major bombing raids from WWII, we usually find them in forest fires; where ascending and converging currents of warm air arise. And although we have recorded tornadoes over a kilometer high and winds over 160 km/h, the truth is that the usual is that they are columns of air about 25-50 meters high and last a few minutes.

A tornado in super slow motion. The best way to enjoy this phenomenon, however, is still another video. In this case of The Slow Mo Guys, some British youtubers that recreated the phenomenon thanks to twelve fans surrounding a metal bucket filled with kerosene in the center: a spectacular column of fire captured in super slow motion and also in 4K.
