Three andesitic subplinian explosions in January 2011 at Shinmoedake volcano, Japan, are used as a case study to validate selected empirical and theoretical models using observations and field data. Tephra volumes are estimated using relationships between dispersal area and tephra thickness or mass/area. A new cubic B-spline interpolation method is also examined. Magma discharge rate is estimated using theoretical plume models incorporating the effect of wind. Results are consistent with observed plume heights (6.4-7.3 km above the vent) and eruption durations. Estimated tephra volumes were 15-34x10(6) m(3) for explosions on the afternoon of 26 January and morning of 27 January, and 5.0-7.6x10(6) m(3) for the afternoon of 27 January; magma discharge rates were in the range 1-2x10(6) kg/s for all three explosions. Clast dispersal models estimated plume height at 7.1 +/- 1 km above the vent for each explosion. The three subplinian explosions occurred with approximately 12-h reposes and had similar mass discharge rates and plume heights but decreasing erupted magma volumes and durations.", "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/s00445-014-0823-9"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1432-0819", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Fukashi Maeno", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masashi Nagai", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Setsuya Nakada", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Rose E.
