Kīlauea is not erupting. Increased earthquake activity and ground deformation at Kīlauea’s summit began at approximately 12:00 p.m. HST on June 2, 2024, indicating the likely movement of magma in the subsurface. 

HVO/USGS Volcanic Activity Notice

Volcanic Activity Summary:

Kīlauea is not erupting. Increased earthquake activity and ground deformation at Kīlauea’s summit began at approximately 12:00 p.m. HST on June 2, 2024, indicating the likely movement of magma in the subsurface. Rates of seismicity and deformation increased further after 5:00 p.m. HST. At this time, it is not possible to say with certainty if this activity will lead to an eruption – the activity may remain below ground. However, an eruption in Kīlauea’s summit region within Hawai‘i Volcanoes National Park is one potential outcome.

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

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

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.  

Hazards are still 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.

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: Vog information can be found at  

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.
