The former poles are soon located somewhere between the Tropic of Cancer and the Tropic of Capricorn, where the weight of the polar ice cap leaves a large circular depression and other dramatic geological changes occur as the huge quantity of water is released by the ice caps melting. Called "capsizing" in the novel the
