The VLP events occurred repeatedly during a few days prior to caldera formation and essentially vanished following the onset of caldera collapse. Waveform inversions of the pulse-like signals point to a source offset 3.5. km beneath and 1. km south of the summit. A candidate for the source mechanism is the inflation of an elliptical cylinder with axis tilted 20-30° from vertical and major axis of the elliptical cross section oriented northeast-southwest. The inferred mechanism appears consistent with a step-like pressurization of a magma reservoir impacted by a falling rock mass in response to gravitational instability. The repeated occurrences of the rock collapses lead to the caldera formation at Miyake-jima. c 2012 Elsevier B.V.", "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": "10.1016/j.epsl.2012.09.039"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0012-821X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tomokazu Kobayashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takao Ohminato", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshiaki Ida", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Eisuke Fujita", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Intermittent inflations recorded by broadband seismometers prior to caldera formation at Miyake-jima volcano in 2000", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Intermittent inflations recorded by broadband seismometers prior to caldera formation at Miyake-jima volcano in 2000", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/2788", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "2788", "relation": {}, "relation_version_is_last": true, "title": ["Intermittent inflations recorded by broadband seismometers prior to caldera formation at Miyake-jima volcano in 2000"], "weko_shared_id": -1}
