Fire tornado in Brazil and Hawaii (Reflection)

A rare weather phenomenon called a fire tornado occurred in Brazil and Hawaii over the past week and both events were captured on video.
The brush fire in Brazil, that produced a rare fire tornado followed 3 months of very dry conditions. The whirlwind of flames burned through fields beside a road in the northwest city of Aracatuba in Sao Paulo state briefly before dissipating.
In Hawaii, a large brush fire that charred over 1400 acres and created a fire tornado also followed very dry conditions. The  fire tornado was captured near Saddle Road on the Big Island, where firefighters worked to contain the blaze.
Also known as “fire devils” or “fire whirls”, fire tornadoes occur when a brush fire or wildfire is whipped up by strong, dry air currents to form a vertical whirl, which can consist of a whirlwind or hot air around or within the flames or vortex itself.
Fire tornadoes are usually 30-200 ft and a few meters wide, and last only a few minutes, but can reach more than a half a mile into the air, contain winds over 100 mph, and persist for more than 20 minutes.
Most large fire tornadoes are formed when a wildfire converges with a warm updraft of air, and can contain a number of fire whirls of varying intensity, size and duration.
While these fire whirls did not cause major problems, there have been some extreme events involving fire tornadoes in the past.
Near San Luis Obispo, California on April 7, 1926, a rash of large fire whirls developed after lightning struck an oil storage facility, killing two. Thousands of whirlwinds were produced by the four-day-long firestorm, which contained larger fire whirls that carried debris 3 miles away.
In Japan, the 1923 Great Kanto earthquake ignited a large city-sized firestorm that produced a large fire whirl, which killed 38,000 in fifteen minutes in the Hifukusho-Ato region of Tokyo.
