The effusive eruption of the volcano continues characterized by the actively growing lava dome.
The extruded lava dome is about 93 m tall, 231 m wide and 511 long and had a volume of 5.93 million cubic meters by 1 February reported by the University of the West Indies Seismic Research Centre (UWI-SRC).
On 1 February a gas measurements revealed the presence of sulfur dioxide (SO2) emissions, first since the eruption started. The absence of sulfur dioxide (SO2) emissions in the early stages of the eruption was due to the interaction of SO2 with the groundwater as SO2 dissolves in groundwater. The gas escaping suggests that the groundwater is drying up.
Remaining gas measurements detected the presence of hydrogen chloride (HCl), hydrogen fluoride (HF) and hydrogen sulfide (H2S).
Gas-and-steam plumes continue to rise from the top of the dome as well as along the contact of the 1979 dome and the new dome.
Daily observations confirmed a continuous fire in the NW area of the crater that affected vegetation on vertical slope of the crater.
The Alert Level remained at Orange.

Sulfur dioxide emissions continue to escape from the area between the pre-existing 1979 dome and the actively growing dome.

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
