KILAUEA VOLCANO

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Kīlauea volcano is erupting from a single vent in the western wall of Halemaʻumaʻu crater. As of this morning, November 23, 2021, all lava activity is confined within Halemaʻumaʻu crater in Hawai‘i Volcanoes National Park. Seismic activity and volcanic gas emission rates remain elevated.

Summit Observations: Sulfur dioxide (SO2) emission rates remain elevated, with an emission rate for November 22, 2021, of approximately 6000 tonnes per day, recorded during a short-lived increase in lava effusion. The average SO2 emission rate for recent weeks is approximately 3000 t/d. Summit tiltmeters overall recorded weak deflation over the past day. Seismicity remains stable. Earthquake activity remains below background and volcanic tremor remains elevated since the beginning of the eruption.
