These photos were taken by someone during the biggest disaster that ever happened to Doncaster, about 20 tornadoes swept the city to ruins, and below are some photos that the institute thinks it is the best.

	"Must be a bad harvest this year, but no worry, Mayor Check will pay me the loss,"says the farmer.
	A waterspout!
	Cars have been taken up into the air!
	Worst nightmare, tornado in the Downtown!
	Ruins lie everywhere in the once most crowded district. Only the lucky buildings can survive. What can we do to prevent this thing happen?

       Well, tornadoes can't be prevented, the only thing you can do is pray that it the tornado won't end up in your downtown, your power plants, or any other expensive buildings, and be relief that the tornado is only attracting tourists by swinging up the water in your lake. But what if it really ends up in your downtown? Be grateful for the invention of save and load and load your city again and say nothing has happened to my city. You didn't save your city? Hope you can afford the maintience cost.

Research on tornado:

1. No buildings can be saved if it is in front of the tornado, not even the military base, a tornado is the most violent atmospheric storm,. a powerful vortex which can spin faster than 300 m.p.h!
2. You can only activate the warning siren when the disaster has happened and killing your sims! Hope there will be more advanced devices to detect tornadoes before it has happened.
