Evolution of castings
The evolution of the flows has remained stable in the last hours and their fronts have not experienced movements, with the exception of the one that reached the sea at Playa de Los Guirres during the early hours of Wednesday, beginning a new lava delta that overlaps the previous one to the north.
Vicente Soler, CSIC volcanologist, has indicated that this new plume (column) of lava is heading towards Las Manchas, but in the last hours he has lost strength “and the wind easily knocks him down.”
According to the latest data from the Council of La Palma, the total area affected by lava has already exceeded a thousand hectares, specifically 1,005.8 hectares, while maintaining a maximum width between casts of 3,100 meters.
As for air quality, there has been an improvement in the five municipalities in the west of La Palma, where yesterday The daily fine particle threshold was not exceeded at any station on the island.
The emission of sulfur dioxide (SO2) also maintains low values in general and is at good or reasonably good levels, with the exception of “some specific moment of regular air quality “in Puntagorda, according to the Department of Homeland Security. Regarding the meteorological conditions, the ash cloud moves to the west and maintains a favorable scenario for aeronautical operations.
