Hawaii , Kilauea :

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE , U.S. Geological Survey
Saturday, January 31, 2026, 9:23 AM HST (Saturday, January 31, 2026, 19:23 UTC)

19°25’16 » N 155°17’13 » W,
Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary:
The Halemaʻumaʻu eruption of Kīlauea is paused. Intermittent glow was visible overnight from both vents. Summit inflation and seismic tremor continued over the past 24 hours. The forecast for the onset of episode 42 lava fountaining is between February 10 and 16 based on current rates of summit inflation. The forecast window will be refined as more data become available. No significant activity has been noted along Kīlauea’s East Rift Zone or Southwest Rift Zone.

Summit Observations:
Intermittent moderate glow from the south vent was visible on webcams overnight, similar to recent nights. Less glow was visible from the north vent compared to recent nights, but it did emit occasional flames including a large, bright flame at 10:37 p.m.
The Uēkahuna tiltmeter (UWD) has recorded 15.2 microradians of inflationary tilt since the end of episode 41, including 1.3 microradians of inflationary tilt in the past 24 hours.

Seismic tremor continued over the past 24 hours. Recurring pulses of increased tremor beneath the summit occurred several times per hour. Four earthquakes were located beneath Kīlaueaʻs summit over the past 24 hours.
The sulfur dioxide (SO2) emission rate from the summit was last measured on January 14 at 1,550 tonnes per day, which is within the typical range of 1,000 to 5,000 tonnes of SO2 per day observed during previous eruptive pauses. This is considerably lower than rates observed during lava fountaining episodes.

Rift Zone Observations:
Rates of seismicity and ground deformation remain very low in the East Rift Zone and Southwest Rift Zone. SO2 emissions from the East Rift Zone remain below the detection limit.

Indonesia , Dukono :

Mount Dukono erupted on Sunday, February 1, 2026, at 11:15 a.m. (local time). An ash column was observed approximately 300 meters above the summit (at an altitude of about 1,387 meters). This thick, white column extended southeastward. At the time of writing, the eruption was still ongoing.

Seismic Observations:
One eruption earthquake with an amplitude of 8 mm and a duration of 30.9 seconds.
Two tectonic earthquakes, separated by amplitudes between 10 and 12 mm and durations of 58.51 to 60.92 seconds.
Continuous seismic tremor with amplitudes between 1 and 4 mm, primarily 2 mm.

VOLCANO OBSERVATORY NOTICE FOR AVIATION – VONA

Issued : February 1 , 2026

DAILY REPORT ON THE STATE OF SANGAY VOLCANO, Sunday, February 1, 2026.
Geophysical Information Institute – EPN.

Surface Activity Level: High, Surface Trend: No Change
Internal Activity Level: Moderate, Internal Trend: No Change

Seismicity: From January 31, 2026, 11:00 AM to February 1, 2026, 11:00 AM:

Seismicity:
The table below shows the number of seismic events recorded at the reference station:
Explosions (EXP): 179

Precipitation/Lahars:
No precipitation was recorded in the volcano area. **In the event of heavy rain, the accumulated materials could be remobilized, generating mud and debris flows that would cascade down the volcano’s flanks and flow into nearby rivers.**

Ash emissions:
No gas or ash emissions were observed by the monitoring camera system. However, several plumes of gas and ash were detected by the GOES-19 satellite system, reaching an altitude of less than 1,000 meters above the crater rim and drifting westward. In this regard, the VAAC agency in Washington issued three reports of ash emissions reaching an altitude of 1,100 meters above the crater rim and drifting southwest and west-southwest.

Other monitoring parameters:
Over the past 24 hours, the FIRMS satellite system recorded 13 thermal anomalies, the MIROVA-MODIS system 2 thermal anomalies, the MIROVA-VIIRS 375 system 1 thermal anomaly, and the MIROVA-VIIRS 750 system 2 thermal anomalies.

Note:
At the time of writing, the volcano remains completely obscured by clouds.

Alert level: Yellow
