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"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4465", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4465", "relation": {}, "relation_version_is_last": true, "title": ["Seismicity and crustal structure related to the Miyake-jima volcanic activity in 2000"], "weko_shared_id": -1}
