Stromboli (Eolian Islands, Italy): Activity at the volcano remains very high. Frequent and often strong strombolian eruptions occur from several active vents in the crater terrace.
The effusion of lava from the SW rim of the crater rim seems to have increased its activity during the past day, and feeds a lava flow that reaches ab out half way down the slope of the Sciara del Fuoco.

Aso (central Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ACTIVITY CONT. VA AT 20190818/1800Z FL060 EXTD NW OBS VA DTG:18/1750Z

Sangeang Api (Indonesia): 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 5 kts in W direction.
The full report is as follows: INTERMITTENT VA EMISSION TO FL080 EXT W OBS VA DTG:18/1945Z to 8000 ft (2400 m)

Fonualei (Tonga, Tonga Islands): A new eruption, likely submarine, has occurred (or is still in progress) during the past days west of Vava'u Island in the Tonga archipelago. Its origin volcano is still a bit unclear, but the eruption, evidenced by fresh pumice rafts and steam plumes is most likely from a submarine volcano near or a vent of the small Fonualei volcano.
