Volcano Lightning

via Gfycat

This is called a dirty thunderstorm and yes if you thought a volcano could not get any more dangerous, it can, when it is accompanied by lightning. This is just an example of what hell would look like if it existed. This is a rare phenomenon and personally, this is one of those rare sights that I would rather not witness live. This looks sublime at a distance but close up this would be plain terrifying.
But there are some things in nature that you should definitely witness at least once in life!
