Why do some of the houses catch fire due to lightning?
Because that's what pure energy does, burn things!
Lightning can strike a building and it will catch fire because lightning is electricity. So in other words it would kind of be an electrical fire, which are more dangerous. It should be more apt to strike a tall tree or something else around the building that's taller than the building, but if the building is just on a big flat field--a miniature prairie--and there's nothing around it for the lightning to strike, what then?
Do you know that grain silos can explode? Throw up enough grain dust particles, start one bit burning and the rest wilflsh/explode. This is what happens in houses. Usually the passage of lighting disturbs the air and throws up a large amount of dust particles. all t takes is a spark from a heater, fire, overloaded wire, etc, then it can all explode. Also can happen when people have incorrectly maintained lightning rods The lightning stike has to arc across a join in cable or earth pipe and this can ignite the dry weatherboard of a house.
