A reassessment of current volcanic emissions from the Central American arc with specific examples from Nicaragua

Abstract: A summary of volcanic gas fluxes in the Central Americ Arc volcanoes of: San Miguel, Arenal, Poas, Momotombo, Itzalco, Santa Ana, Pacaya, Fuego, Santa Maria, Tacana, Masaya, Telica and San Cristobal from 1997 through 2004. SO2 flux was analyzed by Differential Optical Absorption Spectroscopy (DOAS) approach (Galle et al, 2003) method Includes analyses of concentrations of major cations and anions in the gas and particle phases analyses of volcanic emissions, in addition to oxide concentrations of volcanic arc glass (Masaya: Pele hair and Bombs). Flux measurements are then calculated with previously published data for mean flux input and output estimates for the whole Central American Arc.

摘要：本数据集汇总了1997年至2004年间中美洲弧带13座火山的气体通量数据，包括圣米格尔、阿雷纳尔、波阿斯、莫莫通博、伊萨尔科、圣安娜、帕卡亚、富埃戈、圣玛丽亚、塔卡纳、马萨亚、特利卡与圣克里斯托瓦尔火山。其中二氧化硫（SO₂）通量采用差分光学吸收光谱（Differential Optical Absorption Spectroscopy, DOAS）方法（Galle等，2003）进行分析。本数据集还涵盖火山喷发物的气相与颗粒相主要阴阳离子浓度分析，以及火山弧玻璃（马萨亚火山：佩莱发丝与火山弹）的氧化物含量分析。随后结合已发表的平均通量输入与输出估算数据，计算得到整个中美洲弧带的通量测量结果。
