Santiaguito - Front of the lava flow towards the El Tambor channel - image Sentinel-2 bands 12,11,05 of 29.10.2022 - Doc .Insivumeh - one click to enlarge

The Santiaguito volcano observatory reports abundant white outgassing at a height of 500 meters, which extends over 4 kilometers to the southwest.

During the night, an incandescence is observed in the crater of the Caliente dome, and in the middle and at the front of the lava flow in a west and south-west direction. Weak avalanches of blocks and ash are observed in the middle and at the base of the western lava flow. This causes the uplift of fine ash particles in the volcanic perimeter.

The volcano maintains high activity due to blocky lava extrusion in the coipole of the Caliente dome, in a west-southwest direction and unstable material in the crater. There is a likelihood of moderate to strong pyroclastic flows , so you should not stay near or in riverbeds near the slopes of the volcano.
