the volcano stops emitting ash and flights resume

The Cumbre Vieja volcano, on the Canary Island of La Palma, has been active this Wednesday for 81 days and continues to expel water vapor and gases, but has stopped emitting ashes, as confirmed by the director of Pevolca, Miguel Ángel Morcuende, that has pointed out that despite the fact that some parameters of the volcano show symptoms of less activity, such as seismicity, there are still no signs that the eruption is going to end.

The favorable evolution of the ash cloud has allowed airlines to resume operations with La Palma after this Tuesday they were forced to suspend flights due to the variability of the ash cloud, at a critical moment, since during this festive bridge of the Constitution, many tourists visit the island to see the eruption of the volcano .

The Minister of the Presidency, Félix Bolaños, said on TVE, after presiding this Wednesday the meeting of the Mixed Commission for the reconstruction, recovery and support of the island of La Palma, in the Salazar Palace, and after meeting with those affected by the eruption, they have reached an agreement to “streamline even more the aid process“and that they are” in a position to be able to resolve already about a thousand requests each week so that before the end of the year all requests are resolved. “

The southernmost wash moves through destroyed areas

In relation to air operations on the island, Morcuende explained there is “a smaller volume of ash emitted from the cone” but also the wind “has rolled slightly and that has allowed the operation within the airport to be possible “.

Meanwhile, one of the streams, the one that is further south, continues to “move through the areas that it previously destroyed” so the authorities are not concerned at the moment, as explained by the director of the Pevolca Plan, who recalled that this laundry has destroyed 60 buildings in its wake.

“As long as this laundry remains where it is circulating, having as it has it already has an exit to the Las Hoyas area, we are not worried because it will not destroy more buildings, but if there were any kind of spill we would be concerned again and to put in an undesirable situation in the matter of destruction of buildings “, has indicated the director of the Pevolca (Plan of Volcanic Emergencies of the Canary Islands) Miguel Ángel Morcuende, interviewed in TVE.

The seismicity remains low and continues under the central zone from Cumbre Vieja in the same areas of previous days, most of the earthquakes of the last 24 hours have been located at depths between 9 and 22 kilometers, according to the report of the National Geographic Institute (IGN).

Can’t talk about the end of the eruption yet

However, the director of Pevolca has warned that despite the decrease in parameters such as seismicity, there are still “a series of variables that still have to go down a lot to be able to think about the end of the eruption.”

Morcuende explained that although the amounts of sulfur dioxide are much smaller than they were on September 23 and it has been decreasing with some peaks, “we are still at very high values.” Besides, the Seismicity is much lower, especially at deep levels than a month ago, but there are still “a significant number of earthquakes“.

Regarding the cracks in the secondary cone, Morcuende explained on TVE that the IGME (Geological and Mining Institute) has been closely observing the cracks and that the opinion of both IGME and the National Geographic Institute, as well as the University of La Laguna is that “in the event that the wall of the cone breaks apart, it would fall into the cone and would not cause added problems.”

The amplitude of the tremor signal (vibrations caused by magma in the volcanic building) is kept at low levels and just as stable as in previous days, points out the IGN.

Regarding the deformation of the terrain, the network of permanent stations on the island does not show a clear trend in the stations closest to the eruptive centers, while in the rest of the stations the slight deflation has stabilized, the daily report collects.
