HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Thursday, March 30, 2023, 8:50 AM HST (Thursday, March 30, 2023, 18:50 UTC) |
KILAUEA VOLCANO (VNUM #332010) 19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m) Current Volcano Alert Level: ADVISORY Current Aviation Color Code: YELLOW |
Activity Summary: Kīlauea volcano is not erupting. The summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, has been paused since March 7, 2023. Lava is no longer flowing on the crater floor. Resumption of eruptive activity may occur in the near future with little or no warning. No significant changes have been observed along either of the volcano's rift zones. Low rates of ground deformation and modest rates of seismicity continue across the volcano. Halemaʻumaʻu Lava Lake Observations: No active lava has been observed over the past 24 hours. A live-stream video of the inactive western lava lake area is available at https://www.youtube.com/usgs/live. Summit Observations: Uēkahuna tiltmeter is recording minor deflation at the summit as part of a DI event. Seismicity is at background levels. The last SO2 emission rate of approximately 155 tonnes per day (t/d) was measured on March 21. Rift Zone Observations: No unusual activity has been noted along the Rift Zones; steady rates of ground deformation and seismicity continue along both. Measurements from continuous gas monitoring stations in the middle East Rift Zone are below detection limits for SO2. Hazard Analysis: Recent eruptions at the summit of Kīlauea Volcano have been occurring within a closed area of Hawaiʻi Volcanoes National Park. High levels of volcanic gas are the primary hazard of concern, as this hazard can have far-reaching effects downwind. Large amounts of volcanic gas—primarily water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2)—are continuously released during eruptions of Kīlauea. As SO2 is released from the summit, it reacts in the atmosphere to create the visible haze known as vog (volcanic smog) that has been observed downwind of the volcano. Vog creates the potential for airborne health hazards to residents and visitors, damages agricultural crops and other plants, and affects livestock. For more information on gas hazards at the summit of Kīlauea, please see https://pubs.er.usgs.gov/publication/fs20173017. Vog information can be found at https://vog.ivhhn.org. More Information: The Hawaiian Volcano Observatory is one of five volcano observatories within the U.S. Geological Survey and is responsible for monitoring volcanoes and earthquakes in Hawaiʻi and American Samoa. |
