In the last week of September, Sabancaya's eruptive activity remained at a moderate level, with an average of 21 explosions per day; they were accompanied by ash plumes at a maximum height of 3,700 meters above the crater and a dispersion towards the south, within a radius of 50 km. Hybrid earthquakes, related to the rise of the magma, remain low in number and energy.

Sulfur dioxide flows remain high, with a maximum of 3,250 tonnes per day on 29 September.

Six thermal anomalies, between 3 and 20 MW, were recorded by Mirova.
