当象关东大震灾那样的地震袭击东京时,每个人所居住的地方会怎样呢?继1975年11月之后,东京都在1984年5月29日第二次发表了全区划分成500米见方的网格,根据地基和建筑物的强度和火灾的危险等推算出的“区域地震危险度”,并绘制出了调查图。尽管工商业者聚居区和知识分子、月薪生活者聚居区等中央线沿线危险度仍旧很高,但由于推算危险度的方法有所改变,耐火混凝土建筑物也在增加等原因,使“非常危险”的地区由以前的9个减少到3个,使“相当危险”的地区由309处减少到218处。因此,东京都做出了“都内抗震安全度已有提高”的结论。
When an earthquake such as the Kanto Earthquake struck Tokyo, where did everyone live? After November 1975, Tokyo published the second time that the entire area was divided into 500 meters square on May 29, Of the grid, based on the foundation and the strength of the building and the danger of fire and other projections of “regional seismic hazard”, and draw the survey map. Although the risks are still high along the Central Line, such as commercial and industrial-enclave areas, intellectuals and residential areas with monthly salaries, the “very dangerous” factors such as the method of estimating the degree of danger and the increase of refractory concrete structures are also causing the “ From 9 to 3, reducing the number of ”quite dangerous“ areas from 309 to 218. Therefore, Tokyo made the conclusion that ”seismic safety in Tokyo has been improved."
