Technically, only the fact that the world started burning is significant. That a big fire continues to burn for 1 hour, that is not so surprising; unless the fire is violating the known laws of physics in some other ways.
If your explanation for the fire is that you got insane and see hallucinations, than the amount of time you keep perceiving those hallucinations might matter.
The continuation of the burning makes the hallucination hypothesis less probable, for as long as it continues. Also, if it continues past the laws of physics, as you point out.
