Llaima volcano (Chile), activity update: fluctuating strombolian activity
Thu, 14 Feb 2008, 19:02
19:02 PM |
Llaima continues to be active. On 6 February, intense Strombolian activity that propelled material 500 m above the summit crater was observed. 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 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.
