Volcano Updates

The USGS Hawaiian Volcano Observatory issues Volcano Updates for Kīlauea as activity warrants.

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: No significant change; Kīlauea volcano is not erupting. A minor increase in earthquake activity has been observed beneath the summit and the Upper East Rift Zone over the past 24 hours. Gradual inflation of the summit and upper rift zones continues. Substantial increases in seismicity and/or deformation could result in a new eruptive episode, but presently there are no signs of imminent eruption.

Summit and Upper Rift Zone Observations:  Over the past 24 hours, there were approximately 42 earthquakes detected beneath Kaluapele (Kīlauea caldera) and 38 earthquakes detected beneath the upper East Rift Zone, mostly at depths of 0–2 km (0.0–1.2 mi) beneath the ground surface. A minor increase in earthquake counts has been observed beneath Kaluapele and the upper East Rift Zone compared to the previous day (during which there were 27 events detected beneath the summit and 40 events detected beneath the upper East Rift Zone). All earthquake counts are well below the counts recorded during the June 27–July 1 upper East Rift Zone swarm. All events were smaller than M3. Tiltmeters in Kīlauea summit region (instruments SDH, southwest of the summit, and UWE, northwest of the summit) show longer-term increases in inflationary ground deformation rates over the past day, as well as more minor short-term variations in tilt. GPS instruments around the summit region continue to show longer-term, gradual inflation since the end of the June 3, 2024, eruption. The most recent measurement of the summit's SO2 emission rate was approximately 61 tonnes per day on July 9, 2024.

A map interferogram showing recent deformation at Kīlauea over the timeframe of June 6 to July 8, 2024, is available here: 

Middle and Lower Rift Zone Observations:  Rates of seismicity and ground deformation beneath the middle and lower East Rift Zone and lower Southwest Rift Zone remain low. Recent eruptive activity and ongoing unrest have been restricted to the summit and upper rift zone regions. Measurements from continuous gas monitoring stations downwind of Puʻuʻōʻō in the middle East Rift Zone—the site of 1983–2018 eruptive activity—remain below detection limits for SO2, indicating that SO2 emissions from Puʻuʻōʻō are negligible.

Analysis:  Following the eruption on June 3, 2024, magma has been repressurizing the storage system beneath Halemaʻumaʻu and the south caldera region, activating earthquakes in the caldera south of Halemaʻumaʻu and in the upper East Rift Zone. At this time, it is not possible to say whether this activity will lead to an intrusion or eruption in the near future, or simply continue as seismic unrest at depth. Changes in the character and location of unrest can occur quickly, as can the potential for eruption, but there are no signs of an imminent eruption at this time.

Updates:  The USGS Hawaiian Volcano Observatory (HVO) will continue to provide daily updates for Kīlauea volcano. Should volcanic activity change significantly, a Volcanic Activity Notice will be issued.

Recent Eruption Information:  Kīlauea erupted briefly on June 3, 2024, southwest of the summit region within a closed area of Hawaiʻi Volcanoes National Park. For more information about this eruption, see this webpage:

Hazards:  Hazards 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.

Near the recent Southwest Rift Zone eruption site, minor to severe ground fractures and subsidence features may continue to widen and offset, may have unstable overhanging edges, and should be avoided. Hazards associated with the recent lava flows include glassy (sharp) surfaces that can cause serious abrasions, and lacerations upon contact with unprotected or exposed skin; uneven and rough terrain that can lead to falls and other injuries; or, locally elevated levels of volcanic gases that can lead to breathing difficulty.
