Sinabung (Sumatra, Indonesia): Lava extrusion continues. A series of small to moderately sized pyroclastic flows occurred this morning at the volcano. The flows were likely produced as parts of the upper, unstable and still growing viscous lava dome on the SE flank collapsed:
Whether the apparently more intense activity is a sign of increased lava effusion is difficult to say.
Stromboli (Eolian Islands, Italy): The lava continues to flow through the northern channel on the upper Sciara del Fuoco. Effusion rate remains significant. Small ash emissions continue to occur from the western summit vents.
Karymsky (Kamchatka): A small volcanic ash plume extending NW from the volcano was reported last evening. Karymsky has been producing intermittent small to moderate explosions for several years.
Ontake-san (Honshu): The volcano continues to emit plumes of steam and possibly some ash Tokyo VAAC reports.
In the meanwhile, search and rescue operations continue on the volcano. The death toll from last week’s sudden explosion has risen to 51 fatalities. Most of them were attributed to head trauma (killed by impact of ballistic projectiles in the summit region of the volcano).
Sabancaya (Peru): A pilot reported a volcanic ash plume yesterday at 20,000 ft (6 km) altitude, but it might have been confused with a weather cloud. Seismic activity at the volcano has been very low.
