An interesting disaster

I am reading a book called “Storm Kings: The Untold History of America’s First Tornado Chasers.”  I am currently on chapter 9 and I’ve got to say, it is a really good book.  I just got done with a chapter about the Peshtigo wildfire in October of 1871.  The wildfire was so great that it spread into a town and killed 2000 people.  The enormous heat due to the fire caused a giant convection column to rise.  The moisture withing that column was forming a giant cloud at an enormous rate.  When it was all said and done, the cloud that remained was a destructive pyrocumulonimbus cloud.  Heavy rains fell from it which flushed much of the fire away.  But that was not the end.  Due to the heavy downdrafts from the rain, a self-sustaining thunderstorm spawned.  That storm produced a tornado.  The tornado ripped through fields of fire, soon catching fire itself.  It was a giant fire tornado!  The heat form the tornado was so intense, that it melting the silicates out of the soil, fused them into molten glass as they were flying in mid-air.  Basically, the tornado’s heat turned sand into glass and it was thrown down into the town.  Now, I know that it has been a lifelong dream of mine to spot a tornado, but I know that I do not want to be caught up in a fire tornado!
