Kīlauea’s summit can swell slightly as magma pressure builds beneath it. USGS Hawaiian Volcano Observatory scientists track that deformation with tiltmeters; when sustained lava fountains release pressure, the tilt commonly reverses. The repeating pattern has helped scientists estimate when another fountaining episode might begin—but it is a conditional signal, not a countdown, and recent irregular deformation has made a new forecast window unavailable.
What summit swelling tells scientists
Kīlauea’s current episodic summit eruption is in Halemaʻumaʻu, within the summit caldera, Kaluapele. As magma pressure builds below the surface, the summit deforms and the ground tilts by a small amount. Tiltmeters record those changes, which scientists interpret as clues to pressure changes in the volcanic system.
Before recent fountaining episodes, tilt has generally been inflationary: the ground tilts in a pattern consistent with pressure building. When sustained high fountains begin, tilt typically switches to deflation as pressure is released. The USGS Hawaiian Volcano Observatory (HVO) puts the timing rule this way: “The switch to deflationary tilt generally defines an episode start.”

Repeated inflation-and-deflation cycles gave HVO a recognizable pattern to monitor. During more regular phases, scientists could use the changing deformation signal to publish probability windows for a possible next episode. A window expresses when an episode might occur given the observed pattern; it does not establish an exact start time or guarantee that fountains will follow.
#1 Best Overall
| Monitoring pattern | What it can indicate | What it means for a forecast |
|---|---|---|
| Inflationary tilt | Pressure is building and the summit is deforming. | It can be part of the lead-up pattern used to estimate a possible episode window, but does not identify an exact eruption time. |
| Deflationary tilt | Pressure is being released; sustained fountains commonly accompany this reversal. | HVO generally uses the switch to deflation to define an episode start. |
| Irregular or changed deformation | The established inflation-deflation pattern is not behaving regularly. | A previously useful probability window may no longer be modelable. |
Why the current forecast is uncertain
As of HVO’s October 6, 2026 activity update, both the north and south vents had minor spattering, strong glow and flaming, but the summit intrusion of September 30–October 1 had not reactivated. Episode 55 remained possible, yet HVO said it could no longer model forecast windows because inflation and deflation had become irregular.
An October 7, 2026 USGS status report described a near-surface magma intrusion emplaced September 30 to October 1 along fracture systems associated with the 2018 collapse of Halemaʻumaʻu. USGS said the intrusion changed its interpretation of likely outcomes and that the previously forecastable behavior patterns were no longer evident in monitoring data. Older forecast windows therefore should not be treated as current predictions.
Rank #2
The October 6 notice listed Kīlauea at alert level WATCH and Aviation Color Code ORANGE. These are status designations from that dated notice, not a guarantee of what conditions are now; consult the newest USGS notice for current status.
How this pattern fits Kīlauea’s history
HVO has compared the recent episodic fountaining with Kīlauea episodes at Kīlauea Iki in 1959, Maunaulu in 1969, and the early Puʻuʻōʻō eruption from 1983 to 1986. At Maunaulu, tilt records also showed summit deflation during fountains and inflation during pauses. These comparisons help explain the monitoring pattern, but past episodes do not ensure that today’s eruption will follow the same course.
Rank #3
A USGS National Civil Applications Center account published in 2026, describing monitoring through fall 2025, reported 32 fountaining events and a maximum fountain height of 380 meters (1,247 feet) in that period. The same account reported that the crater floor rose 53 meters (173 feet), from approximately 917 meters (3,008 feet) above sea level in December 2024 to 970 meters (3,182 feet) by fall 2025. These are historical measurements through fall 2025, not totals current to October 2026.

Areas around the active crater are closed to the public because volcanic conditions can cause serious injury or death. Hazards identified by USGS include volcanic gases such as sulfur dioxide, Pele’s hair and other volcanic fragments, unstable crater walls, ground cracks, and rockfalls. Follow park closures and official instructions rather than approaching a closed area to view activity.
For remote viewing, USGS provides official summit webcams and livestreams. Conditions and visibility can change, and remote viewing does not replace current safety notices.
