Cities: Skylines

For all of the natural disasters, there are two ways for them to occur. The first is through natural occurrence in the game, the other is to activate it yourself.

The first option can be manipulated in the “Options” section when you pause the game. On the “Gameplay” tab, under “In-Game Settings”, there is a “Use random disasters” choice that you can toggle on or off. Below that is “Random disaster frequency” that has a slider bar. Set it as you wish. Personal note: I had it set right in the middle, playing for 3 hours on 3X speed in 150,000 person city, I experienced 0 disasters


The second option will get these achievements quickly. There is a new Button choice at the far right of the toolbar labeled “Disasters”. There are two tabs in this section labeled “Evacuation” and “Disasters”. Push to select “Disasters”.

For this particular achievement push a few times and “Sinkhole” is the last one. Select it and the disaster will occur in a few minutes. I thought it hadn't activated at first, but it will happen if you give it a few minutes. The emergency radio voice will announce a sinkhole is imminent. If you have placed Earthquake Sensors, I believe it gives more heads-up.
