The number of volcanic earthquakes declined to an average of 2-3 events per day during the first week of January. Rockfalls from the summit dome occurred at a rate of 0-1 events per day, indicating that lava dome growth had slowed.
Sulfur dioxide flux averaged 1,148 tonnes per day (t/d) in 2024, with a high value of 2,394 t/d on 22 January to a low of 420 t/d on 5 March; overall sulfur dioxide emissions remained above the background level of 500 t/d and were consistent with a non-eruptive, degassing dome.

Crater incandescence was visible daily. The seismic network recorded a few volcanic earthquakes and rockfall signals during the week.
Moderate emissions were observed almost daily that rose as high as 500 m above the summit and drifted multiple directions. On 10 February sulfur dioxide gas emissions were measured at 1,875 tonnes per day. The Alert Level remained at 2 (on a 0-5 scale).
Residents were reminded to stay away from the 6-km-radius Permanent Danger Zone (PDZ) and pilots were advised to avoid flying close to the summit.
