Natural and catastrophic disasters

For higher/custom difficulties it would be interesting to see major disasters like floods, hurricanes, and landslides or refinery explosions, fires, rocket failures, and nuclear meltdowns to add to the difficulty and realism. Man-made disasters could be tied to a lack of maintenance, keeping maintenance high would reduce disaster chances

I would agree that some man-made disasters would be good in the game but there needs to be a way to avoid them form happing and not be random chance.
But we also have a weather system in place. With that at times we should look at potential of disasters that would happen in the world with weather. As we are on an Island we would most likely face a hurricane or two.
