USGS-HVO Lowers Alert Level On Kilauea

7:43 PM · Mar 21, 2023

Kīlauea is no longer erupting. Lava supply to the Halemaʻumaʻu lava lake ceased on March 7 based upon lava lake levels and behavior of the crater floor. Sulfur dioxide emissions have decreased to near pre-eruption background levels. Current Volcano Alert Level: ADVISORY - Current Aviation Color Code: YELLOW Previous Volcano Alert Level: WATCH - Previous Aviation Color Code: ORANGE Accordingly, the USGS Hawaiian Volcano Observatory (HVO) is lowering the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW. Seismicity and deformation patterns remain unsettled. Resumption of eruptive activity may occur in the near future with little or no warning. Potential remains for resumption of this eruption or initiation of a new eruption at or near the summit of Kīlauea. HVO continues to closely monitor Kīlauea for signs of renewed activity. Should volcanic activity change significantly, a new Volcanic Activity Notice will be issued. Hazards are still present on Kīlauea and are described below. Residents and visitors should stay informed and follow County of Hawai‘i and Hawaiʻi Volcanoes National Park guidelines. ---- Image and caption from USGS ---- View of Halema‘uma‘u crater floor looking south and showing the island that formed during the December 2020 eruption (foreground) and crater floor (background). photo by D.
