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.
