Fagradalsfjall (Reykjanes Peninsula, Iceland): (24 Mar) For those interested in understanding of how the current eruption works from a geology point of view and what can be said (or not) about its future, we recommend this brilliant post on Volcano Cafe: The Reykjanes eruption: a look underground!

Klyuchevskoy (Kamchatka): (25 Mar) The phase of the effusive-explosive activity of the volcano ceased as reported volcanological observatory KVERT in their latest issue.
The flank-to-lateral eruption on the northwestern slope began to ceased gradually over the past few days although weak incandescence from the cone and flows were still visible in the webcam images.

...24 Mar:
JMA reported that the seismic network for Suwanosejima's Ontake Crater detected a total of 11 explosions during 12-19 March. These events produced eruption plumes that rose as high as 1.7 km above the crater rim and ejected bombs up to 700 m away from the crater.
Incandescence from the crater was occasionally visible at night. The Alert Level remained at 2 (on a 5-level scale).

Raung (East Java): (25 Mar) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 10 kts in W direction.
The full report is as follows: GROUND REPORT OF DISCRETE ERUPTION TO FL150 to 15000 ft (4600 m)

Ibu (Halmahera, Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 .

Merapi (Central Java, Indonesia): Glowing avalanches continue to occur from the active dome, which actually grows in two relatively independent parts to the SW and SE, as our correspondent and volcano guide Galih reported.
According to official information, the volume of the lava dome in the southwest sector is 840,000 m3 with a growth rate of 12,900 m3 / day. The morphological analysis of the peak area based on photos from the southeast sector on March 18, 2021 shows the height of the central dome is 65 m, and the estimated volume of the dome is 950,000 m3 with a growth rate of 12,800 m3 / day since January 4, 2021.

Soufrière St. Vincent (West Indies, St. Vincent): (24 Mar) The lava dome continued to slowly grow during 17-23 March, expanding to the N and S. A team visited the dome on 19 and 23 March to make observations, take measurements, and maintain monitoring equipment.
Gas-and-steam continued to rise from the top of the dome as well as along the contact between the old and new domes.
As of 19 March the dome was 105 m tall, 912 m long, 243 m wide, and had an estimated volume of 13.13 million cubic meters. The Alert Level remained at Orange (the second highest level on a four-color scale).
