The principal subject of this research is to make sure the fundamental characteristics of microtremors. Because the application of microtremors to practical engineering purposes is actually expected. Most of all, to confirm the stability and applicability of microtremors, we made a joint measurements in the Fukui plain as a very important test field. As the background, the 1948 Fukui earthquake was considered to be compared with the 1995 Hyogoken-Nanbu earthquake, because of similarities on earthquake magnitude, focal depth, very strong motion and heavy damage. The joint measurements of microtremors were very successful to confirm the fundamental characteristics and its applicability.Individual experiments in each district were also made by every investigators, such as Ishikari plain, Hachinohe area, Kanto plain, Sagami plain, Nobi plain, Osaka and Hanshin plain, Saijo basin in Hiroshima, besides Fukui plain. These results were reported and discussed in the research meetings and workshops, those were held very often in the Research term. Some of the research fruits were also presented in the international conferences in Taiwan and USA.

本研究的主要目的是确定微震的基本特征。因为微震应用于实际工程目的实际上是令人期待的。最重要的是，为了确认微震的稳定性和适用性，我们在福井平原作为一个非常重要的试验场进行了联合测量。作为背景，1948年福井地震被认为与1995年兵库县南部地震进行比较，因为地震震级、震源深度、强烈震动和严重破坏具有相似之处。微震的联合测量非常成功，证实了其基本特征及其适用性。每个调查人员还在石狩平原、八户地区、关东平原、相模平原、浓尾平原、大阪和阪神平原等各个地区进行了单独的实验，广岛西条盆地，除福井平原外。这些结果在研究会议和研讨会上进行了报告和讨论，这些会议和研讨会在研究学期经常举行。部分研究成果还在台湾和美国的国际会议上发表。
