The ash ash plumes rose up to 500 meters above the crater. The lava dome is highly active, and tilt measurements support observations of lava dome growth. This information was summarized from Smithsonian Institution's Preliminary Notices of Volcanic Activity . On 25 January, the Alert level was raised to 3. An Alert Level 3 means that there is an increased tendency towards eruption.
Magmatic outbursts are possible within the coming weeks.
On 10 January, an active lava dome was confirmed. Monitoring networks have reported numerous volcanic earthquakes, continued swelling of the edifice, and very high gas outputs from the summit crater. This information was summarized from Smithsonian Institution's Preliminary Notices of Volcanic Activity . Lava dome growth was occurring at the volcano's summit that coincided with a slight ground tilt. Volcanic gases were released, and there was a significant increase in earthquake occurrences.
