Sulfur dioxide (SO₂) emissions was also identified in satellite data on 30 October and 2 November.An observation flight confirmed that the ash plume was rising 400–500 m above sea level and drifting southeast for about 5–8 km. According to the modelling, the activity is unlikely to cause ashfall on the mainland. Continued minor ashfall on the island has led to the accumulation of fine ash on the main crater floor. Vent temperatures are around 250 °C—higher than the previous two measurements before the latest activity, but still well below the peak of about 500 °C recorded earlier this year.Based on recent observations, the Volcanic Alert Level remains at Level 3 (minor volcanic eruption), and the Aviation Colour Code remains Orange. These levels reflect both the prevailing low-level activity and the uncertainty surrounding volcanic behaviour due to the current absence of real-time monitoring equipment on the island.Popocatépetl (Central Mexico): (4 Nov) Explosive activity continues.
