canonically there have been various disasters that have hit Springfield my favorite one would be the episode Hurricane Neddy where homer and lisa have an arguement:
Homer: "Oh Lisa! There's no record of a hurricane ever hitting Springfield."
Lisa: "Yes, but the records only go back to 1978 when the Hall of Records was mysteriously blown away."
In-game you do have building facades of a "disaster" struck kind of building the swat tank comes to mind, it can hit the brown house, kwik-e mart or the quick & fresh place, as such each has a facade making it look as if hit by a tank.
only issue, is, would it be in bad taste?
Your intentions mean well, but if a natural disaster hit during the event some media may take that BS spin and call EA "insensitive" or someone playing may be insulted as they or a loved one may have survived said natural disaster and feel the portrayal was insensitive.
Or i dont know, if there is money in it, maybe EA will do it, however it will require of Ralphs "Ralphisms", for example if theres a storm and it begins to flood he might say " Uh oh gods watching Titanic again" or if there is an earthquake "Gods girlfriend is visiting him again" something like that
