The largest earthquake swarm ever recorded in Japan began off the islands of Miyake-jima, Kozu-shima and Nii-jima, and was linked to volcanic activity on Miyake-jima, at the northern end of the volcanic front of the Izu-Ogasawara (Bonin) arc. Ocean bottom seismographic observations made directly above the swarm region gave clear indication of a magmatic intrusion. The hypocenter distribution shows a vertical sheet, 2 km wide and at a depth of 12-20 km, that broadens markedly at depths up to 12 km. The P wavespeed structure obtained from a seismic refraction survey shows no significant difference in the characteristics of the shallow crust between the strong swarm region and inactive region. However, a low wavespeed region was detected 10-15 km northwest of Miyake-jima.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1029/2002GL015008"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1944-8007","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishizawa, A.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ono, T.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Otani, Y.","creatorNameLang":"en"}]}]},"item_title":"Seismicity and crustal structure related to the Miyake-jima volcanic activity in 2000","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seismicity and crustal structure related to the Miyake-jima volcanic activity in 2000","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":"4465","relation_version_is_last":true,"title":["Seismicity and crustal structure related to the Miyake-jima volcanic activity in 2000"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T01:54:20.345158+00:00"}
