Svartsengi (Reykjanes peninsula, SW Iceland): (19 Mar) The seismic activity near the Sundhnúkur crater row has shown a clear weekly increase, except for the final week of February, likely due to weather conditions.
A previously seismic station that caused measurement disturbances has now been corrected. The earthquaks persist in the same area as before previous eruptions—between Sundhnúkur and Stóra-Skógfell—where magma first surfaced in six of the seven eruptions since December 2023.
Deformation measurements, including GPS data, indicate the ongoing uplift, albeit at a slightly slower rate. There are no signs of subsidence around Svartsengi, as confirmed by GPS and InSAR observations. Magma continues to accumulate beneath Svartsengi, now reaching its highest volume since the eruption sequence at the Sundhnúkur crater row began in December 2023.

I am surprised this is all. Thre vocanoe only. Good job I am only looking to report three. Not happy!
First of all the triples:
Nevado del Ruiz (Colombia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210.
This is the theatre that the air war over Germany was fought over. The best British and almost all the German interceptors were able to reach a lot higher but the Allies were bombing at just below this height.
Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 18000 ft (5500 m) altitude or flight level 180 .
18 thousand I am not certain this height registers as a succinct volcano)
Reventador (Ecuador): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA ;EMS DTCTD Volcanic ash emissions detected. Is that a joke; maybe I should give it a day?
Santiaguito (Guatemala): (19 Mar) Mild explosive activity continues from the volcano. The Volcanic Ash Advisory Center (VAAC) Washington reported intermittent emissions of volcanic ash plumes.
The full report is as follows: sporadic emissions of volcanic ash Let’s try a day later.
