The effusive eruption of the volcano continues accompanied by actively growing lava dome.
Read more...On 16 January the volcanologists of the University of the West Indies Seismic Research Centre (UWI-SRC) did a
rock sampling from the western part of the growing lava dome.During the field sampling a thermal images were taken to measure a current
surface temperature approx. 590 °C as hot rising magma pushes its way up to the surface. Glow identified in satellite data suggesting rise of the magma. The aerial survey will be used to create a detailed model of the dome which will help map the growth and volume of the lava dome in the future.

Higher and bigger actively lava dome on the edge of the 1979 lava dome (image: @scarlett_jazmin/twitter)
The effusive eruption of the volcano continues.
Read more...The University of the West Indies Seismic Research Centre (UWI-SRC) in collaboration with geologists prof. Richard Robertson, Dr. Thomas Christopher and Dr. Adam Stinton did an aerial flights over the volcano to observe actively growing lava dome. They were able to take thermal images of heat distribution, gas emission and dimension measurement of the new dome.
The
actively extruded lava dome area located on the edge of the old lava dome from 1979
continues to grow and is
higher and bigger than reported in the last update. It continues to grow laterally towards the east and west. [

Actively growing lava dome associated with elevated surface temperature visible from space (image: Sentinel 2)
The effusive eruption of the volcano continues and has remained essentially unchanged since the last update.
Read more...The University of the West Indies Seismic Research Centre (UWI-SRC) led by geologist prof. Richard Robertson in collaboration with National Emergency Management Organization (NEMO) reported that the
new extruded lava dome remains active on the edge of the old lava dome from 1979 and still growing in size.
Visibility for aerial flights of the new effusive phase was very limited due to dense clouds yesterday, but the event is possible to observe from the Belmont observatory. [

New lava dome growth accompanied with lava effusion at Soufrière St. Vincent volcano (image: @uwiseismic/twitter)
The University of the West Indies Seismic Research Centre (UWI-SRC) in collaboration with National Emergency Management Organization (NEMO) reported that visual observations on 29 December 2020 confirmed a
new lava dome growth located on the edge of the old lava dome from 1979, forming a "dome on rim of the dome". An effusive eruption of the volcano is accompanied with oozing lava and fumarolic activity.
Read more...The last eruption occurred 41 years ago as the series of explosive eruptions ejected the dome and was replaced with another.
The alert level for the volcano was raised to "orange", as an increase of seismic activity at the volcano has been recorded since early November.
