There is many disasters such as floods, volcanoes or raining that you must deal with:
-Flood you would need to just set a builder to remove the water taking 2 days and when the water is gone there is water plants or animals that you can get gems from
-Volcano that brings fire which is put out by water... this leaves ashes that can be used to convert to DE
-Rain could just be a usual thing that nothing really happens from but can rarely cause a flood
-Avalanche- Covers the entire area in snow and can be removed in 6 hours, but if not delt with turns to ice and the ice takes 1 day and 12 hours to clear and if not cleared troops can die by slipping or get injured.
