Soufrière St. Vincent volcano (St. Vincent Island, West Indies): Volcanic Alert Level lowered to Green
The activity at the volcano is now considered to be at levels similar to the activity prior to the 20-21 eruption.
The decreasing trend has continued over the past months.
No significant change in chemical composition has been observed since late January.

Soufrière St. Vincent volcano (St. Vincent Island, West Indies): eruptive phase ended
after almost one year of observations, when the new lava dome at the volcano was detected in December last year and are about to leave the local Belmont observatory.
The Soufrière St. Vincent volcano's activity continues at decreasing values since the last explosive eruption on 22 April and all monitoring data indicate the end of the eruptive episode.
Remaining gas and steam plumes and lahars will be monitored remotely from its base in Trinidad and Tobago.
The UWI-SRC's volcanologist prof. Richard Robertson said: “The mountain went through a traumatic experience and will take some time to reshape itself”.
The alert level for the volcano remains at "yellow".

Soufrière St. Vincent volcano (St. Vincent Island, West Indies): Volcanic Alert Level lowered to Yellow
The activity at the volcano has decreased over the past three months associated by continuous degassing from the summit vent.

Soufrière St. Vincent volcano (St. Vincent Island, West Indies): new images of 2021 crater area and western flanks
A look into the new crater shows several hydrothermal areas that are responsible for a continuous degassing.
A total destruction of vegetation can be observed on the upper slopes of the volcano related to massive eruptions during April this year. This area is currently covered by thick tuff layers (tephra/pyroclastic material deposits) where heavy rainfalls whittled new-formed V-shaped gullies.
They also took a picture of a valley on the western flanks of the volcano that has been affected by pyroclastic flows. This phenomenon is deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes.
In addition, no new lava dome is observed from available images.
Soufrière St. Vincent volcano (St. Vincent Island, West Indies): latest image reveals 2021 crater
The crater is located next to 1812 crater as can be seen in the attached image.
The volcano continues at seismic unrest.
A near-constant gas and steam venting continues from the summit crater. Sulfur dioxide (SO2) emissions reached to a 461 tonnes/day on 20 May.
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.
