Remove Minecraft General Disasters Mod Volcano from World?

In my Minecraft world a volcano has arisen and I would like to remove it somehow, is that possible?

This can be done with mcedit. You can also download the Worldedit mod

I have already deleted the volcano with World edit. But it still fly chunks through the area

No it's not possible. The mod is meant to destroy a world. This is possible with Worldedit, but the Particles are still there.
You could copy the world and remove the mod, or make a backup for the next world.

Thank you.
