To me a 'disaster' is a personal totally unexpected event, where-as something like a series of killer tornados are pretty much expected in the US, so the press don't bother hyping the reports up in order to sell the stories.
Again where our hearts go out to the families who lost loved ones in the Concordia accident or tragedy, I wouldn't call it a disaster unless it was to bring the whole company down, and with the high levels of insurance that will paid out, total ruin of a division of Carni Corp is highly unlikely.
