Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

There have been no major changes in the ongoing eruption at Kīlauea summit over the past day. All eruptive activity is confined within Halema‘uma‘u crater, in Hawai‘i Volcanoes National Park. The vent on the western wall and the fountain within the south-central portion of the lava lake remain the most vigorous and are producing the largest gas plumes. Sulfur dioxide (SO2) emission rates were measured at approximately 14,750 tonnes per day yesterday, October 2. USGS photo taken by L. DeSmither on October 2, 2021.
