Roundup of Global Volcanic Activity:
Etna (Sicily, Italy): No significant changes have occurred. The New SE crater remains restless with some occasional weak activity, visible from time to time as faint glow on the webcam at night. Tremor is currently low.
Suwanose-jima (Ryukyu Islands): Explosive activity has resumed at the remote volcano in the Tokara Island chain. VAAC Tokyo reported explosions yesterday and this morning, with ash plumes rising to 4,000-6,000 ft (1.2-1.8 km) altitude.
Sinabung (Sumatra, Indonesia): The volcano continues to produce near-constant ash venting. The emissions produce a plume rising to estimated 18,000 ft (5.7 km) altitude. It seems that the more powerful discrete explosions during the past days have somewhat cleared the conduit, allowing for a more constant (and less violent) eruption of magma. The risk of sudden, more powerful explosions remains however high, because the magma involved (likely dacite) is very viscous
