Two different types of pressure gauges, i.e., the quartz resonant pressure gauges and the silicon resonant pressure gauges were pressurized by the pressure balance. Pressure fluctuations at a frequency range lower than 0.1 Hz have the same characteristics regardless of the type of pressure gauges, while pressure fluctuations at a frequency range higher than 0.1 Hz are different by 10 dB in amplitude. Compared the experimental data with the in-situ observation data, the amplitude caused by the Rayleigh wave was coincided. However, the pressure fluctuation predominated at 0.1 Hz was not reproduced in the experiment, suggesting an unique phenomenon exhibited only at the seafloor.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 土木学会","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Society of Civil Engineers","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2208/kaigan.78.2_i_169"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-8944","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松本 浩幸","creatorNameLang":"ja"},{"creatorName":"MATSUMOTO Hiroyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"梶川 宏明","creatorNameLang":"ja"},{"creatorName":"KAJIKAWA Hiroaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"有吉 慶介","creatorNameLang":"ja"},{"creatorName":"ARIYOSHI Keisuke","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"高橋 成実","creatorNameLang":"ja"},{"creatorName":"TAKAHASHI Narumi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"荒木 英一郎","creatorNameLang":"ja"},{"creatorName":"ARAKI Eiichiro","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"地震時に海底津波計が観測する動水圧変動に関するデータ解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地震時に海底津波計が観測する動水圧変動に関するデータ解析","subitem_title_language":"ja"},{"subitem_title":"ANALYSIS OF PRESSURE FLUCTUATIONS RECORDED BY PRESSURE GAUGES DURING AN EARTHQUAKE","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-27"},"publish_date":"2023-04-27","publish_status":"0","recid":"3764","relation_version_is_last":true,"title":["地震時に海底津波計が観測する動水圧変動に関するデータ解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T05:20:08.390770+00:00"}
