To explain how perilous a fire tornado is, we would need to go back a little in time. It was in 1923 that an earthquake occurred in Great Kanto, Japan. It was this earthquake that ignited a large city-sized firestorm that in turn produced a fire tornado. Unfortunately, it took this tornado only 15 minutes to kill 38,000 people in an area in Tokyo.
It was during the four-day firestorm that thousands of whirlwinds, tornadoes, and firestorms formed and carried debris as far as three miles away. Fire tornadoes were in the news recently too, when one was produced in South America causing major damage to Brazil and killing many people.
How do fire tornadoes take shape?
Wildfires are the starting point of most tornadoes. Tornadoes are usually present around 30 to 200 feet tall, though there have been reports of some of them being over a mile high and ten feet wide. Usually, fire tornadoes do not last for more than a few minutes, though there have been exceptions to the rule with some going on for more than 20 minutes.
