Hagibis, which means “speed” in the Filipino language of Tagalog, is reportedly the worst storm Japan has seen in 60 years. However, until just a day before, another flurry of images from Japan was causing immense curiosity on social media: A dark pink, almost purple sky.

The storm was devastating and caused great loss of life. A lot of these social media photos “looked fake” or at least over-edited but there’s a scientific explanation for them.
