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.
Thermal images were taken to determine the distribution of heat on the new dome, however conditions and visibility were limited due to dense clouds and not suitable for temperature measuring. The scientists will need to repeat this exercise as the gases coming out of the volcano were moving around and therefore difficult to measure. A plume rising from the lava dome contains sulfur dioxide (SO2) and carbon dioxide (CO2). Carbon dioxide does not have a smell and can be fatal for population.

Soufrière St. Vincent volcano (West Indies, St. Vincent): Volcanic Alert Level raised to Orange; new lava dome growth
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 all
