I also feel that Japan has not experienced the worst yet. I believe it may get to the point that half of Japan will be un-livable. Part may go under the sea and another large quake and possible tsunami will hit once more. 日本はまだまだこれから最悪の事態を経験するとか、日本の半分は住めなくなる(海に沈む)とか言っていて怖い。
あと、I also believe that there will be one incident where both an earthquake, major one, and a volcanic eruption happens at the same time.大きな地震と噴火が同時に起こる(国は言及していない)と言っている
