Lightning strikes.
Lightning happens because of electrical discharges in the atmosphere between two electrically charged areas. Usually happens in rain. It happens near instantly, releasing around 200 megajoules and 7 gigajoules. Air around lightning flashes is extremely hot, around 30,000 Celsius, Florida has the most thunderstorms per year at around 70-100. In the U.S. lightning kills people 93 and injures 300 per year. No place in the outdoors is completely safe from lightning. You should stay inside if there is lightning. In the U.S alone lightning strikes 20 million times each year. If you are outside than you should avoid tall objects because lightning is more likely to strike. Lightning if you get struck by lightning carry no electrical charge and should be given CPR, shock, and first aid if it is safe for the rescuers.
The rarest lightning, also known as a Cloud to Ground lightning, is a discharge between a thundercloud and the ground. They are either positive or negative, and the average electrical current can identify if they are positive or negative. Positive cloud to ground lightning bolts are way stronger than negative cloud to Ground lightning, averaging around 30,000 amperes. Positive lightning makes up about 5% of all lightning strikes.
