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.
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.
Volcanic Hazard Map contains 4 Hazard Zones (Red Zone-Very High, Orange Zone-High, Yellow Zone-Moderate, Green Zone-Low) as can be seen in the image. The warning bulletin states that pyroclastic flows and lahars could affect a land area including offshore and the hazard zones must be envisaged as extending some distance offshore.
