The new fajana of the La Palma volcano that was created this week on the beach of Los Guirres continues to grow thanks to the supply of lava it is receiving from washes 1, 2 and 9, while the rest of the flows remain stable, with lava flowing mainly through areas already trodden and they already have a magma cover on the outside.
The Pevolca technical director, Miguel Ángel Morcuende, reported at a press conference that everything remains in similar circumstances to yesterday, so that there are no overflows or spills to other points, and growth is only taking place in the lava delta.
Miguel Ángel Morcuende indicated that at this time there are 476 people housed, 5 more than yesterday, of which 409 are staying at the Princess Hotel in Fuencaliente and 67 at the Valle de Aridane Hotel in Los Llanos. Likewise, there are 43 dependents in different social health centers on the island.
The technical director highlighted that the seismicity it continues to be maintained at intermediate depths, between 10 and 15 km, and at high depths, more than 30 km, and it is not being recorded at the surface level. Seismicity continues at low values, consolidating the evolution that has been registered in the last two days, and above all, deep seismicity remains constant. Although there has been a decrease in earthquakes, today there has been an earthquake of magnitude 5.0 mbLg, which has been felt with a maximum intensity of IV-V in La Palma, La Gomera and Tenerife.
According to the deformation, a slight vertical deflation is maintained at station LP03, the closest to the eruptive center, and the trend towards stability continues in the rest of the island’s stations.
Also, the emission of sulfur dioxide (SO2) associated with the volcanic plume, it maintains the same magnitude in terms of tons as in the last two days. Although there was a significant rise three days ago, in the last two days it has been decreasing, as it happened the previous week.
In relation to the meteorological forecast, there will basically be wind from the north and northwest, which causes the dispersion of the ash cloud to be disposed towards the southwest and west, so that the operation of the airports will be favorable. The thermal inversion is around 2,000 meters, favoring the dispersion of pollutants. Also this afternoon Weak rainfall is expected, especially to the north and east of the island. The possibility of the formation of a storm core towards the west of the Canary Islands is also maintained and it will probably be known tomorrow if it affects La Palma.
In terms of air quality, there are still minor SO2 issues. Yesterday there was an overcoming of the daily thresholds in Puntagorda and of the hourly thresholds in both Puntagorda and Los Llanos. Right now, the levels are good or reasonably good in all the stations of the island, except in Fat tip, which has reached an unfavorable level at some point during the day, although at present the levels are reasonably good.
Regarding PM10 particles, there are again problems of rebound of these pollutants, especially at unfavorable levels yesterday afternoon. The rest of the stations have been reasonably good or good and it should be noted that the thresholds have not been exceeded in any of the stations.
