Hmm I’m not sure about that. I can’t think of many things that would cause the Earth to explode, but I imagine that if it did, then it would shatter into lots of smaller pieces of rocks which would fly out all over the place. That would probably mean the moon wouldn’t be a very safe place to be – as it would get hit with all of the debris! So whilst we might be able to relocate to the moon, it probably wouldn’t be the best plan.
