Llaima, Chile

SERNAGEOMIN reported intense Strombolian activity in the main crater of Llaima and explosions that propelled material 500 m in the air on 6 February. Ash-and-gas plumes from the activity rose to altitudes of 5.1-5.6 km (16,700-18,400 ft) a.s.l. and drifted SE more than 30 km. Multiple lava flows traveled 0.7-1.5 km W and N and generated steam plumes due to their interaction with a glacier. Activity declined later that day. During breaks in cloud cover, ash plumes were observed at altitudes of 4.1-9.1 km (13,500-29,900 ft) a.s.l. and drifted NW. During 7-8 February, explosions from two different areas in the main crater produced brown and gray ash-and-gas plumes that rose to altitudes of 4.1-6.2 km (13,500-20,300 ft) a.s.l. and drifted 20 km NW. Incandescent blocks from lava-flow fronts rolled down the flank.

According to a news article on 7 and 12 February, people from two communities were evacuated, but were allowed to return to their homes during the daytime.

The Buenos Aires VAAC reported that ash plumes at altitudes of 1.2-3.6 km (4,000-11,800 ft) a.s.l. were visible on satellite imagery during 10-12 February.
