Eruptive activity was primarily characterized by the collapse of new material associated with dome growth. Dome collapse activity produced a total of 72 pyroclastic density currents (PDCs), or pyroclastic flows. Additionally, a total of 338 rockfalls were detected. Increased lava effusion was reported. Crater glow was visible to the naked eye. A significant increase in the Real-time Seismic Amplitude Measurement (RSAM) data was recorded during 15–16 January at three of the sixteen Mayon Volcano Network stations, likely attributable to the elevated rate of rockfalls and PDCs. As of 1930 on 16 January, the RSAM values began to decrease. Strong degassing activity was observed at the summit. Sulfur dioxide (SO₂) emissions averaged 4,970 tonnes per day on 16 January, the highest campaign measurement since 2010. According to a Disaster Response Operations Management, Information and Communication (DROMIC) report, as of 1800 on 16 January, a total of 4,139 individuals (comprising 1,131 families) were evacuated from communities within the 6-km permanent danger zone (PDZ), primarily in Camalig, Guinobatan, Ligao city, Malilipot, and Tabaco city.
