All at the same time, with phenominal deaths and destruction, for prolonged periods of time, and in spades the earth over? Never, that I know of.
Then you need to read more history.
There have been over 350,000 deaths from just two recent events, the Indonesian tsunami and the Pakistan earthquake. This does not include the approx. 50,000 deaths in Iran from two recent earthquakes, the recent hurricanes, volcanos, famines and raging wars in Africa. Nor does it include the estimated millions of deaths worldwide from AIDS, (especially in Africa), over the last decade.
And you can't deny that today mankind has the power to destroy the world all by ourselves with warfare, which makes Biblical prophesy nothing to snicker at.
