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

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.

对中美洲火山弧中的圣米格尔、阿雷纳尔、波阿斯、莫莫通博、伊萨尔科、圣安娜、帕卡亚、富戈、圣玛丽亚、塔卡纳、马萨亚、特利卡和圣克里斯托瓦尔的火山气体通量进行了总结，时间跨度为1997年至2004年。二氧化硫通量分析采用了差分光学吸收光谱法（DOAS）（Galle等人，2003年）方法。数据集涵盖了火山气体和颗粒相中主要阳离子和阴离子的浓度分析，以及火山排放物中氧化物浓度的分析（马萨亚：火山毛和炸弹）。随后，基于先前发表的均值通量输入和输出估算数据，计算了整个中美洲火山弧的通量测量值。
