1995年兵庫県南部地震調査の種類と概要  [in Japanese] Method and information of scientific researches on the 1995 Hyogo-ken Nanbu Earthquake  [in Japanese]

兵庫県南部地震に関連して, この2年半に多くの機関や研究者により多量の調査が実施された。それらの調査の内容を, 地震発生以前から蓄積されていた調査資料・地震時に獲得された資料・地震後獲得された情報・大規模調査により得られつつある資料に分類して簡潔に紹介した。今回の地震を契機に実施された大規模調査の成果は地球科学の基礎情報として極めて重要であること, 地震発生-地震波の伝播-地表の振動-地表の変形・変状-被害の関連性についての議論にこの貴重なデータを生かすこと, その成果を公表・説明することが必要であることを指摘した。

After the 1995 Hyogo-ken Nanbu Earthquake, numerous scientific researches were carried out and much amount data were collected on active faults, seismic characteristics, surface rupture, building damages, and subsurface structure by many organizations and researchers. This paper reviews the kind of the scientific data obtained before and after the 1995 Hyogo-ken Nanbu Earth quake, and introduces the big research projects that have been carried out after the Earth quake. Especially, data on fault activity and distribution by airphotograph and trenching survey, data on subsurface structure by seismic reflection survey, and data on stratigraphy and physical property by drillings are collected during these three years around Osaka Bay including Hanshin Area. The severely damaged area by this earthquake was well known for its neotectonic activity during Late Quaternary, and many geological and geophysical information had been collected in this area before this earthquake. However, these information was not used efficiently for seismic hazard mitigation. This indicates that distribution and explanation on these earthscience information to citizens are very important role of earth scientists.
