Shiveluch (Kamchatka): The volcano continues to slowly extrude viscous lava at its dome. An ash plume was produced this morning that rose to 13,000 ft (4.2 km) altitude and drifted SE. Most likely, it had been caused by a small to moderately large collapse on the eastern flank:

Dukono (Halmahera): Several ash plumes were observed during the past days, suggesting that explosive activity (probably strombolian-type) at the remote volcano remains elevated.
Tungurahua (Ecuador): Since the major explosion on 14 April, activity at the volcano has been characterized by several smaller and moderate explosions and near-constant steam and ash emissions that mainly drifted west and SW.
On 15 April, an eruption column rose about 5 km above the crater and drifted westward, causing ash fall in the towns of Mocha and Tisaleo.
IGPEN's monitoring data suggest that a new magma batch is currently rising from deeper sources into the volcanic edifice and will likely produce more volcanic activity in the coming days: Seismic data show the persistent presence of numerous long-period earthquakes typical of fluid movements. Deformation data indicate continuing inflation on the flanks of the volcano. SO2 plux has been measured to over 1500 tons per day.
Ubinas (Peru): Near-constant small to moderate explosions and ash emissions continue. Occasionally, incandescent fragments are ejected outside the crater.
INGEMMET volcanologists climbed the volcano on 15 April and observed that the recent explosive activity had destroyed the small lava dome in its summit crater (it had been observed during previous field surveys on 1 and 19 March). At its place, a deep pit crater could be seen:

Kilauea (Hawai'i): Kilauea summit tiltmeters record continued DI inflationary tilt (+3 microradians over the past 36 hrs) and the lava lake is now at an estimated 48m (157ft) below the floor of Halema`uma`u crater. Gas emissions continued to be elevated at the summit eruption. The Pu`u `O`o eruption, on the East Rift Zone of Kilauea, continued to be sluggish with no significant changes. ... Lees alle

Fuego (Guatemala): Activity at the volcano continues to increase and could be heading towards a new paroxysm with lava flows, strong explosions and potential pyroclastic flows. Constant avalanches were observed on the upper southern flank, which could be related to the opening of an effusive vent. ... Lees alle
