SO2 emission rates from Kilauea Volcano, Hawaii (2014-2017) This report documents the SO2 emission rates for the period 2014-2017, from the summit and East Rift Zone eruptions of Kīlauea, along with the wind or plume speed and direction data used to calculate the emission rates. The Kīlauea summit SO2 emission rates are reported every ten seconds, as measured by a novel configuration of 10 fixed, upward looking UV spectrometers (FLYSPEC array), and for days with at least 2 hours of data, the daily means are reported. The plume or wind speeds used to calculate the emission rates are measured by cross correlation of plume features (see William-Jones and others (2006)) or by ground-based anemometer (SDH) and are reported with the emission rates. When the SDH ground based wind... Categories: Data; Tags: FLYSPEC array, Halema'uma'u, Kilauea Crater, Kilauea East Rift Zone, Kilauea volcano, All tags...

Changes in emission rate are often associated with changes in volcanic activity and in some cases may herald future changes in activity. At the Hawaiian Volcano Observatory (HVO), emission rates of SO2 from Hawaiian volcanoes have been measured by ultraviolet spectrometer since the late 1970s [Casadevall and others, 1987]. Here we present a compilation of SO2 emission rate measurements made from 2018 to 2022. The emission rates (in t/d) span five orders of magnitude through a range of activity styles unprecedented in recent times, including caldera collapse [Anderson and others, 2019], the first prolonged...
