We read a passage relating to natural disasters in Taanit 5a in which Rabbi Nachman asks Rav Yitzchak to explain a passage from Kings II 8:1 in which the people are told that they will suffer through a famine for seven years. He asks: how can they possibly suffer famine for seven years without supplies of food? Rabbi Yitzchak replies by quoting from Rabbi Yochanan who explains this verse in the following fashion: in the first year they will eat from the fields. in the second year they will eat what they have managed to save; in the third year they will eat their kosher animals; in the fourth year their trefah animals: in the fifth year they will eat the insects and reptiles: in the sixth year they will eat their children: and in the seventh year they will eat the flesh from their own arms. Thus they will survive.
Where else in the Talmud can we find a discussion of natural disasters?
