The University of the West Indies (UWI) revealed another new post-eruption aerial images taken on 12 June. Pilots from HMG Guardian focused on the 2021 crater area and western flanks of the volcano.

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.
