The new thermal anomaly from 26 May is highly likely to indicate the lava flow emanating from the western slope (image: Sentinel-2, processed by Martin Kelko)

A new thermal anomaly detected by Sentinel‑2 indicates that a new lava‑flow eruption is likely underway. It appears that a new flank vent has opened on the western slope, suggesting that magma has intruded into a dyke.

Regarding the explosive activity, near‑constant weak to moderate Vulcanian‑style eruptions continue at regular intervals of one to two per hour.

Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 and is moving at 10 kts in E direction.
