Sulfur dioxide emissions from the La Palma volcano show that the end of the eruption "is far away"


The director in the Canary Islands of the National Geographic Institute, María José Blanco, he explained, along with director of the Canary Islands Volcanic Prevention Plan, Pevolca, Miguel Ángel Morcuende, that this deformation of the terrain has already occurred on two occasions and has been accompanied by an increase in lava and the closing or opening of some emission point, always in the exclusion zone.

However, Blanco has explained that a campaign will be intensified to analyze the veracity of the data on the deformation of the terrain that is observed in the station near the eruption but not the other stations, which suggests that, if the measurements, this is a very superficial phenomenon.

At the press conference, Morcuende pointed out that the sulfur dioxide emissions from the eruption show that the end of this volcanic emergency "is far away."

Specifically, it has detailed that the emission of sulfur dioxide is 40,400 tons per day.

As for the diffuse emission of carbon dioxide, which showed a decreasing trend between October 12 and 22, it has risen again and yesterday there were 1,121 tons per day.

The wind will blow from north to east in the next 36 to 48 hours, which augurs a favorable scenario for operations at airports, and it is not ruled out that fine ash reaches the island of El Hierro.

The scenario is favorable for air quality but in Fat tip The hourly threshold for sulfur dioxide concentration has been exceeded, so the Pevolca will monitor this parameter in the next few hours.

In this regard, Miguel Ángel Morcuende has indicated that this situation may derive from the pressure on the local winds and it has indicated that this matter worries Pevolca, which could issue a statement regarding the use of FFP2 masks and the restriction of outdoor physical activities in the aforementioned municipality.

Morcuende has also alluded to the changing configuration of the cone, which continues to send most of the lavas to the west and these continue to fluctuate above and below the oldest streams, in particular the original, 1, and 4, which they are receiving a significant contribution and are filling in "islands" that remained "untouched" on the surface.

This has caused the area affected by magma has increased to 879.69 hectares (27.42 more hectares), while its maximum width has not changed (2,900 meters) and the distance to the sea from the wash 7 is maintained at about 120-130 meters.

Colada 8 is heading southwest and will try to join precisely 7, the "most reasonable" destination, the Pevolca technical director pointed out, but the problem is that if it receives a sufficient load of material it could also start its journey by the north of the mountain of La Laguna.

Currently this laundry is located next to the schoolyard and the La Laguna fire station, while 10 is 600 meters from the Las Manchas cemetery and about 200 meters from the photovoltaic park and the houses of Corazoncillo.

Yesterday was a "very powerful" day seismically and today it is proving similar or somewhat lower, with 15 earthquakes felt, which can produce landslides "at any time", like the one registered this Tuesday in the El Remo area.

The buildings destroyed or damagedAccording to the data provided by the Cadastre, they are estimated at 1,291, of which 1,038 are for residential use, 135 for agriculture, 64 for industrial use, 30 for leisure and hospitality, 11 for public use and the rest for other uses.

For the system Copernicus satellite This figure rises to 2,286 buildings, of which 124 would be at risk.

So far 452 people who have had to leave their home are housed in hotels in Fuencaliente and Los Llanos de Aridane, and 38 dependents are housed in different social health centers on La Palma.
