HVO/USGS Volcanic Activity Notice

Volcano: Kilauea (VNUM #332010)

Current Volcano Alert Level: WARNING
Previous Volcano Alert Level: WATCH

Current Aviation Color Code: RED
Previous Aviation Color Code: ORANGE

Issued: Monday, June 3, 2024, 2:11 AM HST
Source: Hawaiian Volcano Observatory
Notice Number: 2024/H167
Location: N 19 deg 25 min W 155 deg 17 min
Elevation: 4091 ft (1247 m)
Area: Hawaii

Volcanic Activity Summary:

Kīlauea volcano is erupting. A new eruption began at approximately 12:30 a.m. HST on Monday, June 3, likely about a mile (1-2 km) south of Kīlauea caldera and north of the Koa'e fault system and Hilina Pali Road, within Hawai'i Volcanoes National Park.

Accordingly, the USGS Hawaiian Volcano Observatory (HVO) is raising the Volcano Alert Level for ground-based hazards from WATCH to WARNING and the Aviation Color Code from ORANGE to RED.

Glow is visible in webcam imagery, indicating that lava is currently erupting from fissures. The most recent eruption in this region was during December 1974, which lasted only about 6 hours. At this time, it is not possible to say how long the eruption will last.

HVO continues to closely monitor Kīlauea for signs of increasing or decreasing activity. Should volcanic activity change significantly, a new Volcanic Activity Notice will be issued.

Hazards are 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.

Rates of seismicity and ground deformation beneath the East Rift Zone and Southwest Rift Zone remain low. Current activity is restricted to the summit region.

Hazard Analysis: 

Kīlauea summit eruptive activity over the past several years has occurred at the base of Halemaʻumaʻu crater and on the downdropped block, within the closed area of Hawaiʻi Volcanoes National Park. During Kīlauea summit eruptions, the high level of volcanic gas—primarily water vapor (H₂O), carbon dioxide (CO₂), and sulfur dioxide (SO₂)—being emitted is the primary hazard of concern, as this hazard can have far-reaching effects downwind. Passive volcanic degassing can occur from within Halemaʻumaʻu crater even during periods of no eruptive activity. 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 Kīlauea. 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. 

Other significant hazards also remain around Kīlauea caldera from 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.

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