Shiveluch (Kamchatka): A series of eruptions occurred during the past days from the volcano’s growing lava dome. Tokyo VAAC issued alerts about ash plumes rising up to 30,000 ft (9 km) altitude.
Bad weather prevented detailed observations, but most likely, several explosions and/or avalanches with pyroclastic flows occurred.
Ash was dispersed to southerly directions.
Sinabung (Sumatra, Indonesia): The volcano continues to produce occasional (generally smaller) pyroclastic flows triggered by collapsing parts of the still active lava lobe on the upper southeastern flank.
Dukono (Halmahera): A more intense explosion occurred at the volcano, sending an ash plume to estimated 2.4 km altitude this morning (VAAC Darwin). The plume drifted 15 km to the south.
Reventador (Ecuador): Activity at the volcano continues with little changes. Occasional small explosions are being reported to occur from the active lava dome in the crater.
Copahue (Chile/Argentina): The volcano remains restless. Intermittent small to moderate ash emissions from the El Agrio crater and night-time glow continue to be observed at the volcano.
SERNAGEOMIN keeps the alert status at yellow, apparently because no other monitored parameters indicate more elevated activity to be expected soon.
