Indonesia , Ibu :
Mount Ibu experienced an eruption on Tuesday, January 27, 2026 at 8:37 AM WIT. An ash column was observed approximately 800 meters above the summit (at an altitude of about 2,125 meters). This ash column, white to gray in color, was moderately to strongly intense and drifted northeast. The eruption was recorded by a seismograph with a maximum amplitude of 28 mm and a duration of 45 seconds.

Colombia , Puracé – Los Coconucos volcanic chain:
Popayán, January 22, 2026, 10:00 AM
Regarding the monitoring of activity in the Los Coconucos volcanic chain, the Colombian Geological Survey (SGC), an agency under the Ministry of Mines and Energy, reports the following:
The alert level for the Puracé volcano – Los Coconucos volcanic chain – has been lowered from orange to yellow: Active volcano with changes in monitored parameters and other manifestations.
Over the past two weeks, the activity of the Puracé volcano has shown a gradual decrease in several monitored parameters, leading to the change in the alert level from yellow to orange on November 29, 2025. This development indicates a trend toward stabilization of the volcanic system, allowing a return to the yellow alert level. The following technical parameters were taken into account:
● Since January 6, a significant decrease in the frequency and energy of ash emissions has been observed.
● Seismic energy associated with fluid movements within the volcano, which had increased since December 27, 2025, has decreased in recent days.
● The thermal anomaly recorded last December in the volcano’s crater has diminished, and no anomaly has been detected since January 12. This temperature variation was linked to heat transport by gases escaping from the volcano’s interior into the atmosphere.
● Sulfur dioxide (SO₂) emission levels have not shown significant increases or abrupt variations that would indicate an increase in the supply of this magmatic gas.
● Volcanic surface deformation remains at rates similar to those recorded before the orange alert level was raised, with no further changes observed in the deformation process.
It is important to note that, although the monitored parameters of the Puracé volcano – part of the Los Coconucos volcanic chain – are trending towards stability, the situation could deteriorate rapidly at any time, leading to a return to the orange alert level, or even a move to the red alert level. Therefore, it is essential that the public remain vigilant regarding the evolution of volcanic activity and avoid the crater area, as it could be affected by a sudden emission of gas or ash.
The alert level for volcanic activity has been raised to Yellow: Volcano exhibiting significant variations in monitored parameters.

Peru , Sabancaya :
Local date and time: January 26, 2026 – 1:21 PM
Bulletin analysis period: January 19-25, 2026
Volcanic alert level
Orange alert level: The volcano’s eruptive activity has increased significantly. Increased seismic activity, frequent explosions, and emissions of ash and ballistic fragments have been observed.
Conclusions
During this period, three moderate volcanic explosions were detected, generating columns of ash and gas up to 1,800 m above the volcano’s summit, in addition to seismic activity associated with the movement of magmatic fluids and internal fracturing. Therefore, the volcanic alert level remains orange.
Recommendations
Adopt preventive measures in accordance with the current orange volcanic alert level.
Do not approach within 12 km of the crater. In case of ashfall, cover your nose and mouth with damp cloths or a mask. Keep doors and windows closed.
Outlook
Future volcanic explosions generating eruptive columns more than 2 km high are considered likely, potentially affecting districts in the Colca Valley and surrounding areas through the dispersal of volcanic ash.

Daily Volcanic Activity Report. OVSICORI-UNA
Date: January 26, 2026, Updated at: 10:11 AM
Poas Volcano:
Latitude: 10.200
Longitude: -84.233
Altitude: 2,687 m
Observed Activity:
Bubbling activity continues with some regularity. Two events were recorded in the past 24 hours and another this morning at 7:45 AM local time. The seismic signal indicates moderate harmonic tremor, with frequencies between 0.8 and 7 Hz. No significant deformation of the volcanic edifice has been detected. Over the past 24 hours, the CO₂/SO₂ and H₂S/SO₂ ratios, as well as the gas concentration, have remained stable.
Environmental Conditions:
The summit is clear. Winds are blowing from the southwest.
Activity level: Alert (2)
Volcano: Rincón de la Vieja
Latitude: 10.83
Longitude: -85.324
Altitude: 1,916 m
Observed Activity:
The seismic signal shows slight tremor with dominant frequencies between 2 and 4 Hz. No significant deformation of the volcanic massif has been detected.

Mexico , Popocatepetl :
January 26, 11:00 AM (January 26, 5:00 PM GMT)
Activity over the past 24 hours
Fourteen low-intensity eruptions were detected, accompanied by slight emissions of water vapor and other volcanic gases. A volcano-tectonic earthquake of magnitude 1.1 was recorded yesterday at 7:36 PM.
At the time of writing, a continuous emission of volcanic gases is being observed, dispersing in a northeast (NE) direction.
The alert level for Popocatépetl volcano is at yellow (phase 2).
The scenarios considered for this phase are as follows:
Low to medium intensity explosions
Seismic tremors of varying amplitude
Light to moderate ashfall on surrounding towns and some more distant towns
Ejection of incandescent fragments within the 12-kilometer exclusion zone
Lahars (mudflows) could form in ravines due to the accumulation of ash on the slopes and its interaction with the rainfall expected in the coming weeks
Possibility of pyroclastic flows that will not reach inhabited areas.
