Sakurajima (Kyushu, Japan): (21 Jul) The volcano continues to produce relatively frequent and strong ash-rich explosions, but activity has decreased a bit compared to previous days. During last night, it had long-lasting (up to 1-2 hours) phases of continuous ash emissions of various intensity, with dense plumes up to about 500 m height, but completely silent and with no visible incandescence. During other phases, it was emitting a small plume of vapour with some dilute ash.
Explosions occurred at intervals of 1-10 hours, producing large ash plumes, but ejecting relatively few bombs. Small lightnings could be seen in the eruption plumes.

Reventador (Ecuador): (21 Jul) Effusive and explosive activity at the surface as well as seismicity have continued to increase. A lava flow is traveling from the summit crater on the southern side towards the SE flank and there are numerous small explosions which create ash plumes of up to about 1 km height.
In its latest special report, IGPEN summarizes the evolution since 12 July as follows:

Tungurahua (Ecuador): (21 Jul) Activity both at the surface and internal remains at moderately high levels. Since the large vent-clearing vulcanian explosion on 14 July, the volcano has been producing strong strombolian activity and near-continuous ash emissions.
This is accompanied by numerous long-period (LP) earthquakes and an elevated output of SO2 (3000 tonnes per day), as well as inflation at the northern flank in combination with weaker deflation of an area SW of the volcano (where the source of the magma might be located at about 2 km depth).
