Roundup of Global Volcanic Activity

Etna (Sicily, Italy): Activity has decreased. No new ash emissions from the Bocca Nuova could be noticed on webcam images and the strombolian activity at the New SE crater, although still present, has weakened and become much more sporadic as well.

Sangeang Api (Indonesia): After the violent eruption on Saturday, a strong initial explosion followed by at least 3 other, but smaller explosions and ash emissions until yesterday, activity at the volcano has calmed down significantly. Weaker ash and steam emissions still continue but at significantly reduced intensity. The Indonesian Volcanological Survey (VSI) lowered the alert status back to 2 ("waspada") on a scale of 1-4.

Pavlov (Alaska Peninsula, USA): After about 1 year of pause, a new eruption started at the volcano on 30 May. Ground observers saw a small lava flow from a vent on the upper NE side of the cone. "Satellite imagery shows elevated surface temperatures. A low level steam plume is visible in satellite imagery and in the FAA web camera located in Cold Bay. Several pilots reported a gas and ash plume drifting north at 7,000 to 8,000 feet above sea level. Based on these observations AVO raised the Aviation Color Code to ORANGE."

Fuego (Guatemala): Activity at the volcano continued with little variation as intermittent strombolian explosions of small to moderate size. Incandescent material was ejected to about 100 m height and fell back to form glowing avalanches on the upper crater. Ash plumes rose to 400-700 m height and drifted for approx. 8 km before dissipating.
