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.

本研究的主要课题是确定地脉动的基本特征。因为微震在实际工程中的应用实际上是可以期待的。最重要的是，为了验证微震的稳定性和适用性，我们在福井平原进行了联合测量，作为一个非常重要的试验场。作为背景，1948年的福井地震被认为与1995年的Hyogoken-Nanbu地震相提并论，因为它们在震级、震源深度、非常强烈的运动和严重的破坏上相似。除福井平原外，每个地区的研究人员还分别在石卡里平原、八野河地区、关东平原、佐贺平原、野壁平原、大阪和阪神平原、广岛的塞霍盆地等地进行了单独的实验。这些结果在研究期间经常举行的研究会议和研讨会上进行了报告和讨论。部分研究成果还在台湾和美国的国际会议上作了介绍。
