(1) Basic data collection of earthquake swarms associated with a large earthquake or an eruptive activity of volcanoes was conducted by the group members, and bessesary analyzes for the data file input were performed. By those efforts, we had compiled ca. 2000 swarm events on a floppy disc format, and outline of the data file were published.(2) Earthquake swarm workshop was held in Tokyo, and individual research topics related to the swarm data file were discussed amond research members.(3) At the occasion of the '95 International Workshop commemorating the 50th Anniversary of Mt. Showa-Shinzan Formation, held a special technical session discussing the world earthquake swarms.(4) Discussion for the future plan of publishing outline of the data file and also public release plan of the data media in a floppy disc.(5) Information for establishing the World Data File of Volcanic Earthquake Swarm was exchanged between our group and volcano seismologists at Alaska Volcano Observatory, Alaska University (USA) . We discussed for the future plan for world wide contribution of our data file.(6) At several occasion, for example at Matsumae Earthquake Swarm, our group member responded prompyly for the social responce based on the assistance of our new data file. Those examples indicate the importance and effectiveness of the data file as a scientific background at future emergency manadgement and hazard evaluation.(7) General relation between extensive earthquake swam and notable crustal deformation was noted, and it is concluded that individual phenomena should be treated from the view point of common regional crustal activity related more wide and comprehensive phenomena under curtain common regional stress field, whatever earthquakes swarms or any kinds of volcanic phenomena.

(1)由课题组成员进行与大地震或火山喷发活动相关的震群基础数据采集，并对输入的数据文件进行基础分析。通过这些努力，我们编制了约。软盘格式的 2000 年群事件和数据文件概要已发布。(2) 在东京举办了地震群研讨会，研究人员讨论了与群数据文件相关的个人研究课题。(3) 在纪念昭和新山形成 50 周年的 95 年国际研讨会上，举行了讨论世界地震的特别技术会议 (4)讨论了未来数据文件大纲的发布计划以及软盘数据媒体的公开发布计划。(5)我们组与美国阿拉斯加大学阿拉斯加火山观测站的火山地震学家交换了建立火山地震群世界数据文件的信息。我们讨论了我们的数据文件的全球贡献的未来计划。(6) 在一些场合，例如在松前地震群中，我们的小组成员在我们的新数据文件的帮助下迅速做出了社会反应。这些例子表明了数据文件作为未来应急管理和灾害评估的科学背景的重要性和有效性。(7)指出了广泛的地震群与显着的地壳变形之间的一般关系，并得出结论，无论是地震群还是任何类型的地震群，都应该从共同区域地壳活动相关的更广泛和更全面的现象的角度来看待个别现象。 火山现象。
