“…VASR* then varies irregularly during the eruption from 0.00068-0.0078 Pa/μm/s, and is higher than the January 31 eruption, mostly because of the very high acoustic amplitudes. The eruption also produced an ashpoor plume to 6.1 km, 0.7 kt of SO 2 , and 21 lightning strokes (Lopez et al 2019;Schneider et al 2019;Van Eaton et al 2019). WorldView-2 satellite imagery from this period (Fig.…”

“…More detailed satellite-based observations and interpretation are available in separate manuscripts, such as Waythomas et al (2019) and Schneider et al (2019). Details on satellite-derived SO 2 and lightning observations are available in Lopez et al (2019) and Van Eaton et al (2019), respectively.…”

“…Changes in infrasound frequency content and the relative proportions of infrasound versus seismic energy suggest that the amount of water involved varied among and within individual events, supporting this hypothesis (Fee et al 2019). Additionally, lighting production (Van Eaton et al 2020), infrasound energy (Lyons et al 2020), and SO 2 mass (this study), which are thought to be controlled at least in part by eruption magnitude, also varied significantly throughout the eruption. A summary of these multidisciplinary observations can be found in Coombs et al (2019) and Table 1.…”

“…We therefore compare event SO 2 masses to complementary datasets to help determine the influence of these controlling factors on the observed SO 2 masses. We compare event SO 2 masses to other eruption parameters quantified by AVO scientists for individual Bogoslof events including lightning stroke number (Van Eaton et al 2020), seismic duration (Searcy and Power 2020), infrasound detection duration, peak pressure and energy (Lyons et al 2020), and infrasound frequency index and range (Fee et al 2019) (Figs. 5 and 6; Table 1).…”
