Roundup of Global Volcanic Activity

Etna (Sicily, Italy): No particular changes have occurred recently. Very sporadic and weak strombolian explosions continue at the summit vent of the New SE crater. Bocca Nuova also continues to produce sporadic ash emissions.

Zhupanovsky (Kamchatka, Russia): A possible new eruption could have occurred yesterday at the volcano, but it could not be confirmed so far. Based on a pilot report KVERT and VAAC Tokyo alerted about a possible ash plume rising from the volcano at estimated 6 km altitude. The alert status of the volcano was raised from green to yellow. If the report is true, it would be the second eruption of the volcano within a relatively short time, the last being from 24 Nov past year. However, no volcanic ash plume could be detected on satellite imagery so far and it could well be a false eruption report.

Batu Tara (Sunda Islands, Indonesia): A volcanic ash plume at 7,000 ft (2.1 km) altitude was observed this morning extending 20 nautical miles to the NW. (VAAC Darwin)

Santa María / Santiaguito (Guatemala): The tropical storm Boris that has been hitting the country over the past days continues to produce heavy rainfalls that in turn cause large mud flows. The large collapse of parts of the lava dome on 9 May has left significant amounts of hot debris at the foot of the volcano, in particular in the upper river bed of the Nima 1. These deposits are now being remobilized and descend the river beds as boiling hot mud flows that contain boulders, tree parts and other debris of up to several meters in size and are extremely destructive.
