Pittsburgh, PA is pretty close to natural disaster free. Some parts of downtown will flood from the rivers, and there have been a couple very small landslides in the last two years from too much rain. But for most of the city, there aren't natural disasters really. No earthquakes, the mountains pretty much prevent tornadoes, no hurricanes, and flooding is not an issue unless you live on the bank of the rivers. Elevation increases pretty quickly as you move away from the river banks.
