应辽宁省地震局邀请,日本横滨大学太田阳子教授,于1988年10月9日至16日来辽宁进行了地震地质考察和学术交流。10月9日太田阳子教授从大连入境,旋即与辽宁省地震局有关科技人员,对大连、熊岳、营口、海城进行了野外地震地质考察。在金州考察海岸阶地时,太田教授对满家滩二级阶地上从贝壳测得的C~(14)年代提出了疑问,她认为与日本及世界各地对比,近2000多年以来,辽宁的海岸不可能有这样快的上升速率。考察过程中,太田教授认为第四纪以来辽东半岛有过高海面时期。在海城震区考察时太田教授指出,开挖探槽研究古地震应当在地形低洼的地方行进。在山脊和山坡上不易保留新的沉积物,
At the invitation of the Seismological Bureau of Liaoning Province, Professor Yukio Ota of Yokohama University in Japan conducted a seismic geological survey and academic exchange in Liaoning from October 9 to October 16, 1988. On October 9 Professor Yuta OTA immigrated from Dalian and immediately contacted relevant scientific and technological personnel of Seismological Bureau of Liaoning Province to conduct the field seismic geological survey of Dalian, Xiong Yue, Yingkou and Haicheng. During the inspection of coastal terraces in Golden State, Professor Ota raised questions about the C ~ (14) dating from seashells on the second terrace of Manjiatan. In comparison with Japan and other parts of the world, she considered that in the past 2000 years, the coast of Liaoning It is impossible to have such a fast rise rate. During the inspection, Professor Ota thinks the Liaodong Peninsula has had a high sea level since Quaternary. When studying in Haicheng earthquake zone, Professor Ota pointed out that the excavation of the trough to study the ancient earthquakes should proceed in the low-lying terrain. Difficult to retain new deposits on ridges and slopes,
