Shiveluch (Kamchatka): (3 Apr) No significant changes in activity occurred recently. The volcano remains active. Slow lava-dome extrusion continues accompanied by ash explosions, incandescence, hot avalanches, and fumarolic activity.

Reventador (Ecuador): (3 Apr) Activity remains high. The volcano produces frequent small ash explosions and lava extrudes in a new flow on the upper eastern flank.
Most of the time, the volcano is in clouds and only occasionally allows direct observations.
Tungurahua (Ecuador): (3 Apr) The volcano continues to be restless with moderate seismic activity. Short emissions occurred occasionally during the past days, but most of them were inferred by seismic signals and could not be observed directly due to cloud cover.
Minor ashfall was reported in El Manzano (8 km SW) and Cahuaji on 26 March. Seismicity was at moderate levels and then declined during 28 March-1 April. Lahars on 31 March traveled down the Vascún (N) and Mapayacu (SW) drainages, carrying blocks up to 1 m in diameter in the latter drainage (from the latest Smithsonian / USGS Weekly Volcanic Activity Report).
Ubinas (Peru): (3 Apr) The volcano has increased its visible activity and produced several more small to medium-sized explosions over the past days. Ash plumes rose up to about 2 km height.
Residents of Querapi village had started to evacuate. Ashfall was reported in Ubinas and Querapi.
