The ash expelled by the new La Palma volcano since the beginning of its eruption on September 19 has covered an area of 3,304 hectares.
This is stated in the latest update of the European Copernicus terrestrial monitoring satellite system with data collected this Friday afternoon.
In the same, significantly reduces the estimate of the area occupied by lava, including the land that has been reclaimed from the sea since the night of the 28th. It goes from 709 hectares to 367.3 hectares.
Regarding the buildings affected by the washings, the calculation of 1,005 is maintained, although those that have been completely destroyed rise to 880, ten more compared to the previous count.
The number of kilometers of roads affected increases to 30.7, of which 28.3 have been destroyed by the passage of lava.
Two new mouths
The molten magmatic material that emerges from the two new emission centers of the Cumbre Vieja volcano, on La Palma, it seeks to join the primal lava flow as it advances towards the sea.
The technical director of the Volcanic Risk Prevention Plan, Miguel Ángel Morcuende, and the director of the National Geographic Institute in the Canary Islands, María José Blanco, explained at a press conference that these two emission centers that were opened at dawn They are about 15 meters apart and are 600 meters from the main cone in a northwesterly direction.
With these two new mouths, there are four sources of lava from the new volcano on La Palma, which, according to Morcuende, maintains an “intense” activity.
Has explained that the two flows advance through a favorable topography and they seek to join with the first lavage that emerged in the eruption, it has crossed the LP-211 highway and continues its evolution at lower levels.

He pointed out that these new flows are continuously monitored to study their evolution and has warned that if any measure has to be taken, the population would be informed.
Morcuende has asked tranquility to public opinion and he explained that there is a volcanic event in which strombolian activity alternates, such as greater explosive phases and the launching of volcanic material, and effusive activity, in which a greater amount of magmatic material emerges.
He has also warned that the area affected by this volcanic eruption represents 10 percent of the island and has ensured that in the rest of La Palma “a normal life is carried out” with some problems such as ash fall.
“Life on the island is normal and smooth” Morcuende has pointed out before the image, he said, an alarmist who wants to present some means of communication. María José Blanco, head of the IGN in the Canary Islands, has specified that the volcanic event maintains the characteristics of a fissure eruption with strombolian phases concurrent with effusive phases.
Blanco explained that the lava delta front (or “fajana”) that has reached the sea is now more than 475 meters from the coastline, reaches a depth of 30 meters and that already this morning occupied an area of 27.7 hectares.
Regarding the marine plume, the cloud that forms when the lava contacts the sea and that may contain toxic gases, the director of the IGN in the islands has appreciated that it is concentrated in the contact area. On seismicity, has commented that in the last 24 hours dozens of earthquakes have been registered, the largest of a magnitude of 3.5, and located between 10 and 15 kilometers deep.
Likewise, other more superficial ones have been registered in the eruptive zone and the level of tremor has increased from three hours today and in some stations close to the lavic deltaor high frequency tremor has been recorded. Blanco recalled that the morphology of the cone changes continuously and reported that the height of the column of ash and gases has reached today the 6,000 meters high.
More confined areas
The direction of the Volcanic Risk Prevention Plan in the Canary Islands, Pevolca, has ordered on Friday night the confinement of several population centers of the municipalities of El Paso and Los Llanos de Aridane due to a worsening of the air quality by the volcanic eruption of Cumbre Vieja.
Specifically, the space between the Crossing of Camino Cruz Chica with the LP-2 highway continuing west until the junction with Nicolás Brito Pais, and from this road to the ring road and through it to the Hoyas Hondas roundabout.
From this point on, the entire area affected by the fire in August is included until El Paso soccer field and the area to the west of the LP-3 up to the Sombrero roundabout.
In addition, the nuclei continue to be confined San Borondón, Marina Alta, Marina Baja and La Condesa collected in the previous update.
The scientific committee warned today that the meteorological conditions could favor a worsening of the air quality which until now remains within the allowed parameters.
80 million cubic meters of magma
The volcano has already emitted 80 million cubic meters of magmatic material, almost double that of Teneguía, which erupted in 1971 and shed more than 43 million.
The description was provided this Friday by the president of the Canary Islands, Ángel Víctor Torres, at a press conference accompanied by the Minister of the Presidency, Félix Bolaños, and the president of the Cabildo de La Palma, after the meeting of the first mixed commission between the State and the Canarian institutions.
Torres has pointed out that “history will tell” what capacity this volcano finally has, but has made it clear that it is still “far” from knowing if the eruption is at the beginning or near the end. “It is not foreseeable that we can say it,” he commented.
The president has also said that the office of attention to the victims will open imminently in the Casa Massieu de The Plains of Aridane with staff from public companies in the autonomous community in the case of GMR, Gesplan, Visocan and Icavi, and has announced the hiring of 14 social workers to assess the personal situation of each affected.
Along these lines, he pointed out that the first 16 homes will be bought next week and the next, another 26, in order to have around a hundred before the end of the year.
In addition, it has made it clear that the “priority” will be for people who have lost their only home and they do not have alternative accommodation -for now there are only less than 200 people rehoused in the Fuencaliente hotel-.
Torres has also commented that work is being done to improve the provisional roads enabled to maintain communication with the coast of Los Llanos de Aridane and in systems that guarantee the supply of drinking water and irrigation if they are finally affected.
The president has insisted that the emergency continues and therefore, has urged to comply “to the maximum” the recommendations of the security operation so that the eruption culminates without personal injury. “We will not be able to replace the pain, although we will make every effort, but the key is that we are all here and there is no relevant personal injury,” he stressed.
Earthquakes in the south of the island
The National Geographic Institute (IGN) has located a total of 12 earthquakes in the last hours in the south of La Palma, near the eruption area, according to the latest updated report from the agency.
As in previous days, the hypocenters are located between 10 and 14 kilometers deep in the same area where the reactivation began on September 11.
Two of the earthquakes have been felt by the population, the largest of them with a maximum intensity of III in the epicentral zone and corresponds to an earthquake of magnitude 3.5 on the Richter Scale at 8:30 p.m. this Thursday.
The mean amplitude of the volcanic tremor remained stable during the morning of this Thursday in a range of mean values for this eruption.
