The Cumbre Vieja volcano, on the Canary Island of La Palma, which erupted on September 19, meets this Friday 89 days and remains for the fourth consecutive day with signs of exhaustionAs the absence of tremor (vibrations caused by magma in the volcanic building), the deformation of the ground is not significant and still does not emit lava from the cone.
The seismicity, both intermediate and deep, remains low. However, the scientists warn that we still have to wait nine days to know if these data are consolidated before we can talk about the beginning of the end of the eruption and that a new rebound in strombolian activity and the emission of runoff cannot be ruled out.
Before the tremor stopped, the volcano emitted huge amounts of sulfur dioxide last Monday and for the first time in this emergency, the 33,000 residents of the three municipalities who have crossed the lava flows (El Paso, Los Llanos de Aridane and Tazacorte) had to remain for almost five hours confined to their homes and the schoolchildren in their educational centers.
The Council of Ministers this Friday will approve a new aid package for those affected by the La Palma volcano, according to the President of the Government, Pedro Sánchez. As he has advanced, the new package of measures will include doubling aid in housing, more direct aid to farmers, ranchers and exempting fishermen from contributing to Social Security while they can not fish.
According to data from the European Copernicus satellite program, a total of 2,988 buildings have been destroyed and the surface area of the island affected by the volcano reaches 1,237 hectares, data that the Pevolca establishes in 1,193 hectares.
Follow here this Friday, December 17, the eruption minute by minute:
The Cabildo de La Palma has just announced through a tweet that This Friday the accesses are open for residents and irrigators to the exclusion zone from the north and from the south, both by sea and land, as the air quality allows it.
“Updated report from the Emergency Directorate as of Friday, December 17, at 8:00 am: ➡ ￏ Access from the north is open. ➡ ￏ Access from the south is open both by sea and by land.“

Regarding the emission of sulfur dioxide (SO2) into the atmosphere by the current eruptive process (visible emanations of volcanic gases), registered, according to the Scientific Committee of the Pevolcan Plan, it remains low, below 5 tons per day (according to Wednesday’s data) and It is not related to a magma ascent, but to a process of solidification of the superficial magma still existing in the ducts of the eruptive center.
A total of 24 low-magnitude earthquakes since last midnight (19 of them have not reached magnitude 2), according to data from the National Geographic Institute. Two earthquakes have had a magnitude of 2.4 mbLg, the maximum recorded during the night, in Mazo, 38 kilometers deep.
Regarding the deformations of the terrain, the lack of a clear trend in the stations near the eruptive center and stability in the rest of the network remains, points out as key data the Institute of Geosciences of the CSIC in Barcelona.
Key data of the eruption at this time: the signs of exhaustion of the eruptive process are corroborated, the visible emission of volcanic gases is sporadic and is concentrated in the eruptive centers and the jameos, points out the Institute of Geosciences of the CSIC in Barcelona in its report that collects data from Pevolca.

The volcano remains for the fourth day without variations with respect to the level of tremor, the seismicity and the emission of gases associated with the volcanic plume, which are at low levels, says the Department of Homeland Security.
The authorities maintain in Los Llanos de Aridane the recommendations to the population due to the high concentration of particles and, due to toxic gases, the need to reinforce protection measures when accessing evacuated areas is recalled, according to the report that gathers data from the Government Canary Islands, the National Geographic Institute and the Cabildo de La Palma.
The The eruptive process continues to show signs of depletion and the visible emission of volcanic gases is punctual. and sporadic and is concentrated in the eruptive centers and the jameos of the volcanic tubes, indicates the Department of National Security in its daily report that collects data from the Volcanic Emergency Plan of the Canary Islands (Pevolca).

You can’t see anything, you can’t hear anything from the Tajuya viewpoint, Francisca González reports in the Morning News of TVE, but that volcano on La Palma is still there. Nothing to do with what we saw on Sunday, Monday, expulsion of pyroclasts, of lava.
At this moment there is nothing left of the five key parameters to begin to glimpse the end, zero deformation, tremor to zero, intermediate and deep seismicity at very low levels, only 13 earthquakes during the early morning and also low levels of sulfur dioxide.
Evacuated by the volcano in a luxury hotel: “You have no life here.” Almost 400 palm trees have been re-housed in the Teneguía Princess, but the passage of time has taken its toll on them. Financial aid to rebuild their lives is slow to arrive, and discouragement is widespread. A report by Samuel A. Pilar (sent to La Palma).
The La Palma volcano has been idle for three days with Christmas Eve as the key date. Scientists have given a period of nine days to certify the end of the eruptive process. In Los Llanos de Aridane the accumulation of PM10 particles continues to affect air quality.
Hello! It begins here, this Friday, December 17, 2021, the minute-by-minute account of a new day with current events on the volcanic eruption on the Canary Island of La Palma.
