The first kind ( PGV(WB)) is obtained from a maximal value of vector sum of the three-component, wide-band velocity seismograms, and the other three kinds ( PGV(BP10), PGV(BP20), and PGV(BP30)) are obtained from a maximal value of vector sum of the three-component, narrow band-pass filtered velocity seismograms ( the central periods are 10, 20, and 30 s). The spatial distribution maps for all kinds of PGV value show azimuth dependence; the PGV values in Hokkaido, northern side of the epicenter are larger than those in Tohoku, southwestern side of the epicenter, when compared at a comparable distance. We find that the features result from the radiation pattern of long-period surface waves, that is, the source effect. The attenuation relationships show the following trends: The PGV(WB) values are larger than the sum of the PGV(BP10), PGV(BP20), and PGV(BP30) at distances ( D) less than 200 km, while the PGV( WB) values are comparable to the sum of the PGV( BP20) and PGV( BP30) at D> 200 km. This indicates that the PGV( WB) values at D< 200 km are affected by ground motions with periods less than 10 s, while long-period surface waves mainly contribute to the PGV( WB) values at D> 200 km. The basin site effects generate a patchy pattern in the spatial distribution maps and a large scattering in the attenuation relationships for the PGV( WB) and PGV( BP10) values. Finally, we conclude that the PGV( WB) values from the 2003 Tokachi-oki earthquake are controlled by the radiation pattern of long-period S and surface waves and various basin site effects.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"SPRINGER","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s10950-007-9076-9"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1573-157X","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takahiro Maeda","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tsutomu Sasatani","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Long-period ground motions from the 2003 Tokachi-oki earthquake","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Long-period ground motions from the 2003 Tokachi-oki earthquake","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"4188","relation_version_is_last":true,"title":["Long-period ground motions from the 2003 Tokachi-oki earthquake"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T01:47:04.429499+00:00"}
