HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, June 6, 2023, 9:08 AM HST (Tuesday, June 6, 2023, 19:08 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. Kīlauea summit is currently exhibiting signs of heightened unrest. Summit seismicity remains elevated. No unusual activity has been noted along Kīlauea’s East Rift Zone or Southwest Rift Zone. 

Halemaʻumaʻu Lava Lake Observations: No active lava has been observed over the past day. A live-stream video of the crater is available at https://www.youtube.com/usgs/live.

Summit Observations: Elevated seismicity continues at Kīlauea’s summit. Daily rates have been variable, but over the past several months, both deformation and seismicity have been elevated beyond observations preceding the January 5, 2023 summit eruption. Summit tiltmeters show inflationary tilt over the past day. Over the past 24 hours, 25 earthquakes were located beneath Kīlauea summit. Most of the earthquakes have been smaller than magnitude-2 and not reported felt. The most recent sulfur dioxide (SO2) emission rate of approximately 100 tonnes per day was measured on June 3, 2023.  

Rift Zone Observations: No unusual activity has been noted along the East Rift Zone or Southwest Rift Zone; steady rates of ground deformation and seismicity continue along both. Measurements from continuous gas monitoring stations in the middle East Rift Zone—the site of 1983–2018 eruptive activity—remain below detection limits for SO2.

Hazard Analysis: Significant hazards around Kīlauea caldera include Halemaʻumaʻu crater wall instability, ground cracking, and rockfalls that can be enhanced by earthquakes within the area closed to the public. This underscores the extremely hazardous nature of the rim surrounding Halemaʻumaʻu crater, an area that has been closed to the public since early 2008. 

For discussion of Kīlauea hazards, please see https://www.usgs.gov/observatories/hvo/hazards.

Please see the Hawaiʻi Volcanoes National Park website for visitor information: https://www.nps.gov/havo/index.htm. Visitors to Hawaiʻi Volcanoes National Park should note that under southerly (non-trade) wind conditions, there is potential for a dusting of powdery to gritty ash composed of volcanic glass and rock fragments. These represent a minor hazard, but visitors should be aware that such dustings at areas around the Kīlauea summit are possible. 

The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea volcano.

HVO will continue to issue daily Kīlauea volcano updates until further notice. Additional messages will be issued as needed.
