HAWAIIAN VOLCANO OBSERVATORY WEEKLY UPDATE
U.S. Geological Survey
Tuesday, March 12, 2024, 8:58 AM HST (Tuesday, March 12, 2024, 18:58 UTC)
KILAUEA (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. Due to continued low rates of seismicity, HVO will issue weekly Kīlauea updates on Tuesdays until further notice. Additional messages will be issued as needed.
Summit Observations: Low levels of seismicity beneath the summit continues. Earthquakes are dispersed widely from the summit to the southwest. There were 40 earthquakes recorded around the summit over the past week. Depths beneath the summit are 0.5-5 miles (1–8 km) below the surface, and magnitudes are typically below M2.0. Ground deformation remains low with tiltmeters near Uēkahuna and Sand Hill showing only modest changes over the past week. Sulfur dioxide (SO2) gas emission rates have remained low since October 2023. An SO2 emission rate of approximately 85 tonnes per day was recorded on March 1. An Information Statement about the recent intrusion can be found here: USGS Volcano Notice - DOI-USGS-HVO-2024-02-09T05:11:03+00:00.
Rift Zone Observations: Seismicity in Kīlauea's upper East Rift Zone and Southwest Rift Zone remain low. No unusual activity has been noted along the middle and lower sections of Kīlauea's East Rift Zone. We continue to closely monitor both rift zones. Measurements from continuous gas monitoring stations downwind of Puʻuʻōʻō in the middle East Rift Zone—the site of 1983–2018 eruptive activity—continue to be below detection limits for SO2, indicating that SO2 emissions Puʻuʻōʻō are negligible. Hazard Analysis: Levels of volcanic gases (sulfur dioxide and carbon dioxide) can remain locally hazardous even when Kīlauea is not erupting. Local concentrations of sulfur dioxide (SO2) and/or hydrogen sulfide (H2S) may persist in downwind areas, and residents may notice odors of these gases occasionally. Significant hazards also remain around Halemaʻumaʻu from crater wall instability, ground cracking, and rockfalls that can be enhanced by earthquakes within the area closed to the public.

Please see the Hawaiʻi Volcanoes National Park website for visitor information: https://www.nps.gov/havo/index.htm. The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea Volcano. Next Notice: HVO will issue weekly Kīlauea updates on Tuesdays until further notice. Additional messages will be issued as needed.
