  abstract = {{E}mission of volcanic gas is thought to be the dominant process by which volatiles transit from the deep earth to the atmosphere. {V}olcanic gas emissions, remain poorly constrained, and volcanoes of {P}eru are entirely absent from the current global dataset. {I}n {P}eru, {S}abancaya and {U}binas volcanoes are by far the largest sources of volcanic gas. {H}ere, we report the first measurements of the compositions and fluxes of volcanic gases emitted from these volcanoes. {T}he measurements were acquired in {N}ovember 2015. {W}e determined an average {SO}2 flux of 15.3 +/- 23 kg s(-1) (1325-ton day(-1)) at {S}abancaya and of 11.4 +/- 3.9 kg s(-1) (988-ton day(-1)) at {U}binas using scanning ultraviolet spectroscopy and dual {UV} camera systems. {I}n-situ {M}ulti-{GAS} analyses yield molar proportions of {H}2{O}, {CO}2, {SO}2, {H}2{S} and {H}-2 gases of 73, 15, 10 1.15 and 0.15 mol% at {S}abancaya and of 96, 2.2, 1.2 and 0.05 mol% for {H}2{O}, {CO}2, {SO}2 and {H}2{S} at {U}binas. {T}ogether, these data imply cumulative fluxes for both volcanoes of 282, 30, 27,1.2 and 0.01 kg s(-1) of {H}2{O}, {CO}2, {SO}2, {H}2{S} and {H}-2 respectively. {S}abancaya and {U}binas volcanoes together contribute about 60% of the total {CO}2 emissions from the {C}entral {V}olcanic zone, and dominate by far the total revised volatile budget of the entire {C}entral {V}olcanic {Z}one of the {A}ndes.},
