究極的人口増加及び大地震発生の危険性からみた既存都市の問題点

抄録

After the oil crises, economic and social development has been suppressed. But, Japanese population continues to increase from 110, 949, 000 in 1975 to 138, 000, 000 in 2025 and almost all this increased population tends to concentrate in large cities.
Another problem in Japan is that there is a possibility to occur large earthquake in megalopolis, such as, Tokyo and that possibility was proved by the study of geophysics. It is estimated that the damages amount aboutr ¥52 trillion at the price level of and national wealth in 1974. Only one method to prevent this great damage of earthquake is to suppress increase in population in Tokyo, but it causes another problem in other cities.
This paper shows these problems using some statistical materials and shows some means of solving.
