Strong winds may waft lighter particles to greater distances. Īdditional hazards include Pele's hair and other lightweight volcanic glass fragments from the lava fountains that will fall downwind of the fissure vents and dust the ground within a few hundred meters (yards) of the vent (s). As SO 2 is continuously released from the summit during the eruption, it will react in the atmosphere to create the visible haze known as vog (volcanic smog) downwind of Kīlauea. Vog information can be found at. High levels of volcanic gas-primarily water vapor (H 2O), carbon dioxide (CO 2), and sulfur dioxide (SO 2)-are the primary hazard of concern, as this hazard can have far-reaching effects down-wind. Hazard Analysis: The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park. Measurements from continuous gas monitoring stations in the middle East Rift Zone-the site of 1983–2018 eruptive activity-remain below detection limits for SO 2. Rift Zone Observations: No unusual activity has been noted along the East Rift Zone or Southwest Rift Zone steady but low rates of ground deformation and seismicity continue along both. Puʻuʻōʻō crater collapsed in 2018 marking the end of its eruptive phase. Residents and visitors should stay informed and follow County of Hawai‘i and Hawaiʻi Volcanoes National Park guidelines.įor more information about the meaning of aviation color codes, see Hazards are still present on Kīlauea and are described below. Should volcanic activity change significantly, a new Volcanic Activity Notice will be issued. HVO continues to closely monitor Kīlauea for signs of renewed activity. There remains the potential for eruptive activity to resume in the near future at or near the summit of Kīlauea with little or no warning. Overnight webcam views showed some incandescence from previously erupted lava as the lava proceeds to cool. Over that period, gradual inflation has been recorded at summit tiltmeters. Seismic activity-including eruptive tremor-in the summit region has been low since the eruption ceased. Sulfur dioxide emissions have decreased to near pre-eruption background levels.Īccordingly, 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. Lava supply to the Halemaʻumaʻu lava lake ceased on June 19 based upon lava lake levels and behavior of the crater floor. Kīlauea volcano eruption continues to be paused with no visible lava flows on the morning of June 20.
