What will happen to America 40 days after the eclipse?

I saw a video where it was the 2017 eclipse and the 2024 eclipse and they make a cross, each of them have seven cities with Nineveh in the name and something else, and in the middle of the cross in a city with rapture in the name and God gave someone, I forgot his name, 40 days to repent. So I don't know if this is a warning about Jesus' second coming because it only happened in America so can anybody give me more of an understanding of this please. Thanks
