Alaid | Kuril Islands (Russia) : The Tokyo VAAC reported that on 20 August an ash plume from Alaid identified in satellite images rose to an altitude of 2.7 km (9,000 ft) a.s.l. and drifted SE.

Kuchinoerabujima | Ryukyu Islands (Japan) : JMA reported that earthquakes at Kuchinoerabujima’s Shindake Crater typically occur at shallow levels, though on 15 August a swarm of deep volcanic earthquakes was recorded, prompting JMA to raise the Alert Level to 4 (on a scale of 1-5). The earthquake hypocenters were about 5 km deep, below the SW flanks of Shindake, and the maximum magnitude was 1.9. They occurred at about the same place as the swarm that occurred just before the May 2015 eruption. Sulfur dioxide emissions had been increasing since the beginning of August; they were 1,600, 1,000, and 1,200 tons/day on 11, 13, and 17 August, respectively. No surficial changes in gas emissions or thermal areas were observed during 16-20 August.

Merapi | Central Java (Indonesia) : PVMBG reported that seismicity at Merapi increased on 18 July, and again on 29 July. On 11 August a large earthquake was detected, and coupled with rumbling heard by Deles residents, possibly signaled new lava-dome effusion. Drone photos on 12 August showed a new lava dome growing within the fracture of the 2010 dome. By 18 August the new dome was 55 m long and 25 m wide, and about 5 m below the 2010 dome surface.
