The inner cone of the La Palma volcano collapses on itself


Experts have warned that the volcanic cone emerged from the eruption that began on September 19 in Old Summit it continually reconfigures itself due to the weight of the magmatic material.

The last rupture occurred on Monday afternoon which caused a large emission of lava..

The deformation of almost ten centimeters of the terrain detected in the area of ​​the Cumbre Vieja volcanic eruption could anticipate an increase in the lava channel or the opening or closing of some emission point.

The director in the Canary Islands of the National Geographic Institute, Maria Jose Blanco, explained, together with the director of the Canary Islands Volcanic Prevention Plan, Pevolca, Miguel Angel 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 off.”

Specifically, he has detailed that the emission of sulfur dioxide is 40,800 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 will reach the island of El Hierro.

The scenario is favorable for air quality but in Puntagorda the hourly threshold has been exceeded in the concentration of sulfur dioxide, 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 in the local winds and has indicated that this matter worries Pevolca, which could issue a statement regarding the use of FFP2 masks and the restriction of physical activities outdoors. in the aforementioned municipality.

Morcuende has also alluded to changing cone configuration, 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 are receiving a significant contribution and are filling “islands “who continued” untouched “on the surface.

This has caused the surface affected by the magma to increase to 879.69 hectares (27.42 more hectares), while its maximum width has not changed (2,900 meters) and the distance to the sea ​​wash 7.

Wash 8 is heading southwest and he will try to join precisely the 7, the “most reasonable” destination, has pointed out the technical director of Pevolca, but the problem is that if he receives a sufficient load of material, he could also start his way north of the mountain of The lagoon.

Currently this laundry is located next to the schoolyard and the La Laguna fire station, while the 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 damaged, according to the data provided by the Cadastre, are estimated at 1,291, of which 1,038 are for residential use, 135 agricultural, 64 industrial, 30 leisure and hospitality, 11 for public use and the rest of other uses .

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

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