Indonesia , Anak Krakatau :

Mount Anak Krakatau had eruptions on Tuesday, October 25, 2022, including one at 07:27 WIB with an ash column height observed at ± 200 m above the peak (± 357 m above sea level) . It is observed that the ash column is black with a thick intensity towards the North-East. This eruption was recorded on a seismograph with a maximum amplitude of 50 mm and a duration of 21 seconds.

Guatemala , Fuego :


The rains in the area of the Fuego volcanic complex are currently generating a lahar in the Barranca Ceniza, a tributary of the Achíguate River, with weak to moderate characteristics, but with the probability of increasing in the next few minutes due to the persistent rains In the region.

The lahar descends fine and hot volcanic materials, in addition to carrying branches and tree trunks, as well as blocks from 30 cm to 1.5 meters in diameter. The rains of the past few days have kept the volcanic deposits saturated with humidity, so that lahars will continue to be generated in the afternoon and evening.

Peru , Sabancaya :

Analysis period: from October 17, 2022 to October 23, 2022, Arequipa, October 24, 2022.
Alert level: ORANGE

The Geophysical Institute of Peru (IGP) reports that the eruptive activity of the Sabancaya volcano remains at moderate levels, that is to say with the recording of an average of 40 daily explosions, with columns of ash and of gas up to 2.9 km altitude above the summit of the volcano and their subsequent dispersion. Therefore, for the following days, no significant change is expected in eruptive activity.

The IGP recorded and analyzed the occurrence of 291 earthquakes of volcanic origin, associated with the circulation of magmatic fluids inside the Sabancaya volcano. An average of 40 explosions was recorded daily, in addition to recording Volcano-Tectonic (VT) type events associated with rock fracturing inside the Sabancaya volcano.


Monitoring the deformation of the volcanic structure using GNSS techniques (processed with fast orbits) does not show any significant anomalies. However, in general, an inflation process was observed in the northern sector (surroundings of the Hualca Hualca volcano). Visual surveillance identified columns of gas and ash up to 2.9 km above the summit of the volcano, which were dispersed towards the eastern, southeast and northeast sectors of Sabancaya. . Satellite recordings have identified the presence of 6 thermal anomalies, with a maximum value of 15 MW, associated with the presence of a lava body on the surface of the volcano’s crater.

• Keep the volcanic alert level orange.
• Do not approach within a radius of less than 12 km from the crater.

Mexico , Popocatepetl :

October 23, 11:00 a.m. (October 23, 4:00 p.m. GMT)

During the past 24 hours, according to the monitoring systems of the Popocatépetl volcano, 27 exhalations have been detected, accompanied by water vapor, volcanic gases and slight amounts of ash. In addition, 635 minutes of tremor, including 300 minutes of low amplitude and high frequency and 335 minutes of harmonic type tremor were recorded.

At the time of this report, the volcano has good visibility, observing a slight emission of gas.

CENAPRED urges NOT TO APPROACH the volcano and especially the crater, because of the danger of falling ballistic fragments and, in case of heavy rains, to stay away from the bottom of the ravines because of the danger of mudslides and of debris.

The Popocatépetl volcanic alert traffic light is in YELLOW PHASE 2.
