Two aerial reconnaissance were carried out on 31.12.2020 at the Soufrière of St-Vincent: a strong cloud cover prevented a good view of the crater during the first reconnaissance; The second aerial reconnaissance was carried out around 4:00 p.m. and the photographer was able to capture photos of the crater, which shows the effusive eruption is continuing and the new dome is also continuing to increase in size.
The alert level remains at Orange. People living in areas near the volcano, which include communities of Fancy in Georgetown and Belle Isle in Richmond, are urged to remain vigilant and listen to any advice from the National Emergency Management Organization (NEMO).
The National Emergency Management Organization reminds the public that no evacuation order or evacuation notice has been given
NEMO is also calling on the public to forgo visiting the La Soufrière volcano until scientists make it known it is safe to do so.

In Kilauea, the western vents of Halema'uma'u crater show spatttering, and feed a lava flow through lava tunnels towards the lake; It continues to widen slowly, its depth reached 186 meters in the afternoon of December 31.
Sulfur dioxide emission ratios remain high, with 4,500-5,000 tonnes per day.
The seismicity remains high, but stable, marked by a high tremor and some earthquakes.

The main island of colder, solidified lava floating in the lava lake moved faster westward, as if searching for the western lava source filling the lake, while the other 10 small islands remained relatively stationary. . around the east end of the lake. The main island measured about 250 m. in length, 135 m. wide and about 3 ha. area according to the heat map of December 30. The measurements on Wednesday evening (December 30) show that the surface of the island was about 6-8 m. above the surface of the lake.
