Posts that depict any kind of world-ending events, such as major or numerous meteor collisions, massive nuclear explosions, etc.
The scale of the threat should be a focus point of the image, and not every picture that simply has fire or destruction in the background should have this tag.
If the world-ending event already happened, see post-apocalypse.
The following tags are aliased to this tag: apocalypse_(event) and apocalyptic (learn more).
