Disasters in Hyrule

The disasters in Hyrule have occurred since the creation of the universe.

The Legend of Zelda
After Ganondorf’s death, a nuclear explosion erupts due to Ganon being the fuel of Twilight and darkness. The results of the disaster caused most of Hyrule to be destroyed. Since the explosion was so effective, it caused a mountain to erupt and flood the land with lava. After getting Zelda back home safely, the explosion ceases and Hyrule is restored.

The Legend of Zelda: The Final Battle
In an attempt to exile Ganon to the Sacred Realm, Midna set off an explosion woth an unknown substance. The shock wave swept along with the destruction across Hyrule. It ended with a colossal nuclear detonation that wiped out the world. However, one final fragment remained which was where Midna headed home to through a gateway.

Afterwards it could be that Hyrule was shut down with the universe dead or it was restored.
