    A lightning stroke generally only lasts for a millisecond, but in some cases currents of 100 amps can persist after a stroke – this is referred to as “hot lightning” which is the cause of 10,000 fires a year in the US.

    Lightning can reach up to temperatures of 54,000 degrees Fahrenheit (30,000 degrees Celsius). Lightning rapidly heats the air in its immediate vicinity about three times the temperature of the sun. Lightning can get so hot that it can fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground.
