A volcanologist Dr. Adam Stinton from the Belmont observatory noted: "Since the morning of Friday 21st, there have been a handful of earthquakes, just around 20-25. None of the earthquakes are large enough to be felt at the moment; the average per day is about 10-15 since the last explosion on April 22nd".
A near-constant gas and steam venting continues from the summit crater.
Satellite-based images confirmed that no actively growing lava dome appears within the summit crater at this moment and there is no indication that the volcano will return to a dome growing phase again. Judging from the attached image, an uplifted area in the inner summit crater may indicate either extruded magma towards the surface or tephra accumulation immediately after the last eruption.
According to NASA FIRMS a high thermal anomaly continues to be detected within the summit crater.
Sulfur dioxide (SO2) emissions reached to a 461 tonnes/day on 20 May.
The Volcanic Alert Level remains at Orange.

Soufriere St. Vincent volcano (St. Vincent) - Smithsonian / USGS Weekly Volcanic Activity Report for 19 May-25 May 2021 (Continuing Activity)
University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that seismicity at Soufrière St. Vincent (often simply referred to as “La Soufriere”) remained low during 17-24 May, with a few long-period and volcano-tectonic earthquakes occasionally recorded. Persistent steaming from the crater was visible on days when weather permitted views, and thermal anomalies continued to be identified in satellite data. ... Read all

Soufrière St. Vincent volcano update: Volcanic Alert Level lowered to Orange
The National Emergency Management Organization (NEMO) in collaboration with University of the West Indies's scientists decided to lower the Volcanic Alert Level from "red" to "orange" as a significant decrease of volcano-tectonic earthquakes have been recorded. In addition, no explosions occurred at the volcano since 22 April. ... Read all
