The only problem with this is that there is no damage model for any of the maps, so things like an earthquake wouldn't really do anything, and if the devs were to implement it, I can only assume that it would take up a lot of space and not really function very well, unless you had an extremely powerful computer. About floods, there is a mod where you can adjust the water level easily (instead of having to use the World Editor). One thing I found about this is that it only seems to affect your car(s), and other cars like traffic cars do not get impacted by this, other than slowing down. This is the mod: https://www.beamng.com/resources/flood.23313/
