I can't point to a "similar legacy of birth defects suffering and eviction from the land" in conjunction with any other kind of disaster, up to and including earthquakes causing millions of deaths.
The 'league' of a disaster in your head is not an important metric; the oil spill is responsible for far more environmental contamination, food supply reduction, and long term ecological damage than Chernobyl.
Coal plants kill more people every year without even being called 'disasters' - the birth defects caused by the radiation being put in the atmosphere by those plants is distributed over a far larger area, but it's way out of the 'Chernobyl league'.
You are attributing extra importance to Chernobyl because it causes an unusual type of localized damage, but it never caused that much of it.
