Kīlauea Volcano Update for Friday, December 19

 

Kīlauea, found inside Hawaiʻi Volcanoes National Stop on the Enormous Island of Hawaiʻi, is one of the most dynamic volcanoes on Soil. Since December 23, 2024, the well of lava has been emitting verbosely from vents inside the Halemaʻumaʻu hole at its summit, creating rehashed scenes of tall magma wellsprings isolated by brief stops.

As of December 19, 2025:

Volcano Caution Level: WATCH

Aviation Color Code: ORANGE

Eruption Status: Summit emission is as of now delayed (no dynamic magma wellsprings at the minute).

 Outline of Current Status (Dec 19, 2025)

 Eruptive Activity

The continuous summit ejection remains stopped for presently — magma wellsprings are not as of now emitting. 

USGS Volcanoes

Intermittent shine was watched overnight at both the north and south vents, demonstrating still-warm magma close the surface. 

USGS Volcanoes

Low-level volcanic tremor proceeds, a common forerunner flag some time recently reestablished eruptive scenes.

 Key Checking Observations

 Swelling and Deformation

Since the conclusion of Scene 38, summit expansion has proceeded. Expansion is measured in microradians (a unit of tilt alter demonstrating magma development underneath the surface).

As of this morning, 26.6 microradians of expansion have been recorded, with almost 1.6 microradians of that happening in the final 24 hours — appearing maintained magmatic weight collection.

💨 Volcanic Gas Emissions

Sulfur dioxide (SO₂) outflows were measured at around 3,400 tons per day — raised relative to delays in past eruptive scenes and well over non-eruptive foundation levels (~100 tons per day). 

USGS Volcanoes

Such lifted gas outflows show that magma is close the surface and degassing, a sign that a modern eruptive stage may be drawing closer. 

USGS Volcanoes

 Seismicity

Low levels of seismic tremors and ground misshapening were show in the East Crack Zone and Southwest Fracture Zone, showing no solid sidelong magma development absent from the summit at this time.

 Estimate: Another Eruptive Scene Likely Soon

Across different later USGS/HVO notices:

Scientists expect the onset of Scene 39 — the following magma fountaining scene — to happen between December 22 and 27, 2025.

Forecasts are based on current swelling patterns, low-level tremor, and gleaming perceptions from the vents — all signals reliable with magma rising to shallow levels.

Important: These estimates are energetic. The estimate interim may alter if expansion rates or other signals change in the coming days.

 Later Logical and Observing Developments

 Unused Camera Deployment

On December 19, 2025, USGS HVO groups introduced a modern V3 webcam along the south edge of Halemaʻumaʻu cavity to supplant cameras devastated by magma in past scenes.

This camera will progress real-time visual checking of volcanic action, making a difference researchers and the open watch changes and react rapidly to eruptive occasions.

 Overflight Observations

HVO geologists conducted ethereal overflights of the summit, recording later tephra and magma stores inside the hole. These flights offer assistance track scene changes and risks related with progressing movement.

 Logical Setting: What This Means

Kīlauea’s summit ejection over the past year has been characterized by long winded magma fountaining — short-lived eruptive beats that can discharge magma hundreds to over a thousand feet into the discuss. 

Wikipedia

This fashion of movement reflects:

A energetic magmatic framework with stages of weight buildup (swelling) and discharge (magma wellspring episodes).

Gas-driven forms and shallow magma developments recognized through tremor and emanation measurements.

Ongoing summit changes inside the Halemaʻumaʻu hole, counting tephra buildup and hole floor changes.

 Risks and Security Considerations

While the ejection is stopped right presently, a few dangers stay relevant:

 Magma Fountaining

If Scene 39 starts as figure, magma wellsprings can reach tall rises, possibly creating volcanic flotsam and jetsam and tephra inside the hole zone. 

usgs.gov

 Volcanic Gasses (Vog)

Elevated SO₂ outflows can lead to vog (volcanic brown haze) arrangement, influencing discuss quality downwind — particularly at lower heights on the Huge Island. 

USGS Volcanoes

 Seeing Region Access

The cavity region where action is happening is closed to the open due to risk potential. Seeing from assigned secure ranges exterior the cavity edge remains the as it were secure choice. (NPS prompts open appropriately.) 

USGS Volcanoes

 What to Observe for Next

Scientists and observatories will proceed to monitor:

 Seismic action increases

 Proceeded expansion at the summit

 Changes in gas emissions

 Warm irregularities close vents by means of toady and ground sensors

 Visual signs (shine) from webcams and ethereal surveys

A design of expanding distortion and tremor, coupled with maintained gas flux, may flag that Scene 39 is inescapable.
