On Thursday, April 22, HVO scientists observed the ongoing eruption at the Kīlauea summit from the south rim of Halema‘uma‘u. This photo shows the active western portion of the lava lake, which appears to be in the process of shrinking again, with its northeast (upper-right) and southwest (lower-left) ends crusting over substantially. For scale, the distance from the western fissure (upper-left) to the nearest part of the main island in the lake (lower-right) is approximately 180 m or 590 ft. USGS image.

Etna (Sicily, Italy): After almost 4 weeks of calm since the last paroxysm (during 31 Mar-1 Apr), the New SE crater is again showing signs of coming back to life:
Two strong strombolian explosions occurred in the night of 24-25 April and in the morning of 26 April at the Southeast Crater, followed by weak glow and smaller occasional explosions since last evening.

Sakurajima (Kyushu, Japan): (27 Apr) The explosive activity of the volcano continues characterized by near-constant vulcanian-type eruptions at roughly regular intervals of 2 per day.
Ash plumes reached approximately 8,000 ft (2,500 m) altitude and drifted E.

Suwanose-jima (Ryukyu Islands): Ongoing vulcanian activity continues characterized by occasional ash emissions from the summit Ontake crater.
The Japan Meteorological Agency (JMA) reported eruption plumes that rose as high as 1.7 km above the crater rim and ejected bombs up to 600 m away from the crater.

Kilauea (Hawai'i): Kīlaueaʻs open lava lake surface has shrunk by almost 25% over the past week, and gas emissions decreased as low lava output continues.
There is still liquid lava below the newly crusted areas on the northeast and southwest lake margins, but it loses some volume as it cools, degasses and compresses. As a result, the recently stagnant surface now sits 2-3 m (7-10 ft) lower than the active lava surface nearby, which itself has slowed its rise to only 0.5 m (1.6 ft) during the past week, only to regain its previous depth of 227 m (745 ft).

Popocatépetl (Central Mexico): (26 Apr) Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA NOT DETECTED

Reventador (Ecuador): (26 Apr) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: DISCRETE VA EM to 15000 ft (4600 m)
