The magnitude-frequency distribution at Suwanosejima volcano, Japan, shows a power-law distribution, which implies self-similarity in the system, as is often observed in statistical characteristics of tectonic and volcanic earthquakes. On the other hand, the magnitude-frequency distributions at five other volcanoes, Sakurajima and Tokachi-dake in Japan, Semeru and Lokon in Indonesia, and Stromboli in Italy, are well explained by exponential distributions. The statistical features are considered to reflect source size, as characterized by a volcanic conduit or chamber. Earthquake generation processes associated with vulcanian, strombolian and gas burst events are different from those of eruptions ejecting large amounts of pyroclasts, since the magnitude-frequency distribution of the volcanic explosivity index is generally explained by the power law.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "SPRINGER HEIDELBERG", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1186/s40623-016-0505-2"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1880-5981", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Takeshi Nishimura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masato Iguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Mohammad Hendrasto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hiroshi Aoyama", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Taishi Yamada", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Maurizio Ripepe", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Riccardo Genco", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Magnitude-frequency distribution of volcanic explosion earthquakes", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Magnitude-frequency distribution of volcanic explosion earthquakes", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5054", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5054", "relation": {}, "relation_version_is_last": true, "title": ["Magnitude-frequency distribution of volcanic explosion earthquakes"], "weko_shared_id": -1}
