Following several months of very dry conditions, a brush fire was sparked in Aracatuba, Brazil. What is unique about this fire is that a fire tornado formed with-in it.
Fire tornados are extremely rare. The fire tornado was caught on camera as it glided across fields and brought traffic on the highway to a stop.
Sometimes called fire whirls or fire devils, these tornados form when very strong winds swirl around the flames. The fire picks up a vertical rotating column of air sometimes containing winds at over 100 mph. They can become several meters high and race across fields as shown in the video.
The most famous fire tornado struck in 1923, during the Great Kanto earthquake in Japan. It ignited a firestorm that raged through the city and produced a gigantic fire tornado that killed 38,000 in 15 minutes in the Hifukusho-Ato region of Tokyo.
