One of the messages was to prepare for the floods and quakes. Although God promised to not destroy the world in this fashion, he did not say that there would be no more floods. If you consider what we have seen in the last 10 or so years I would have to say that the comming ones will be huge. There is a scripture re the earth reacting to the sin of man. Since sin is increasing I would suspect the earth to express its distaste as even nature is aware of God.
