The Center for Volcanology and Geological Hazard Mitigation (CVGHM) raised the Alert Level for Mount Lewotobi Laki-laki from Level III to Level IV at 03:00 LT on February 12 (19:00 UTC on February 12). The volcano exhibited increased activity between January 3 and February 13, with a notable surge in seismic activity. Observations reported white and gray summit emissions, ranging from 50 to 1 500 m (164 to 4 921 feet) in height, with fluctuating intensity. The weather varied from clear to rainy, with winds blowing in multiple directions. Eruptions were recorded with ash columns reaching 500 to 800 m (1 640 to 2 600 feet) above the summit. The presence of faint firelight near the summit suggests that magma is reaching the surface, with a red glow visible at night. The number of harmonic earthquakes has risen indicating increased fluid movement and gas release within the fractures. The rise in low-frequency earthquakes suggests that magma is traveling toward the surface. Visual assessments noted solfatara emissions along a crack on the northwest side of the peak, forming thin to thick plumes. The emissions point to a weak zone which could lead to a directed blast, an eruption concentrated in a specific direction, mainly toward the northwest and northeast. Previous eruptions have deposited volcanic material on the slopes, posing a lahar risk in the event of heavy rains. Communities near Dulipali, Padang Pasir, Nobo, Klatanlo, Hokeng Jaya, Boru, and Nawakote are at increased risk. A surge in volcanic earthquakes was recorded from 22:00 LT (14:00 UTC) on February 11 through February 13, suggesting ongoing magma supply, increasing the likelihood of further eruptive events.
