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.
