Recent destructive earthquakes in urban regions, such as the 1978 Miyagiken-oki earthquake and the 1995 Hyougoken-nanbu earthquake, have triggered instability in many of the gentle slopes in residential areas around Sendai, Nishinomiya and Kobe cities related to the urban development that has continued since the 1920s. The landslide risk maps with earthquake-induced slope-instability that has occurred is closely related to these artificial landform changes, especially with artificial valley fills (embankments) were made. These risk maps, 1/10000 Jiyugaoka, Musashi-kosugi, Tsurumi, and Shin-yokohama, show the potential of future landslide disasters. According to the maps, more than half of fills would be classified into a high-risk of instability group as the unstable fill slope following an earthquake in this metropolitan region. The geological aspects of all government developments plans should considered not only in terms of geotechnical engineering for surveying ground conditions, but also importantly in terms of providing information to residents.

最近发生在城市地区的破坏性地震，例如 1978 年的宫城县大地震和 1995 年的兵库县南部地震，导致仙台、西宫和神户市周边住宅区的许多缓坡不稳定，这与持续的城市发展有关。自20世纪20年代以来。已发生的地震引起的边坡失稳滑坡风险图与这些人工地貌变化密切相关，特别是人工填谷（堤）的变化。这些风险地图（1/10000自由之丘、武藏小杉、鹤见和新横滨）显示了未来滑坡灾害的可能性。根据地图，超过一半的填方将被归类为不稳定高风险组，因为该大都市区地震后的填方边坡不稳定。所有政府开发计划的地质方面不仅应考虑用于测量地面状况的岩土工程方面，而且还应重要地考虑向居民提供信息。
