Average measurements of SO2 from Kilauea summit since 21 December 2020

Graph showing Average measurements of SO2 from Kilauea summit since 12 December 2020

Detailed Description

Sulfur dioxide (SO2) emission rates measured using an upward-looking ultraviolet spectrometer. These data are collected by traversing the gas plume in a vehicle or helicopter, downwind of Halema‘uma‘u, generally within and/or southwest of KÄ«lauea caldera. Results from multiple traverses during a collection period are averaged to yield the emission rates shown here. Successful measurements depend on wind, weather, and staff availability. Values are preliminary and are subject to revision.
