The earthquake could most easily be implemented by giving all solid blocks the falling attribute of sand and gravel.

That is actually a good point - however from the point of trying not to meddle too much with game internals it may be safer to just run a compaction routine over the map data.

Just thought of something. You should check out the "tornadoes" mod. It would be perfect for this world.

If it's not already, then I think it should be pvp without the option to turn it off. I mean, who wouldn't go pvp during an apocalypse?

Sounds epic.
