SANTA CRUZ DE LA PALMA, Oct 21 (EUROPA PRESS) –
The two lava flows that cross the La Laguna neighborhood, in Los Llanos de Aridane, have merged into one and are advancing towards the southeast to bar behind the mountain, although he does not rule out that when they ‘intersect’ a trough they jump to another basin and affect the coastal highway, which is why on Wednesday night some 150 residents of the neighborhoods of Las Martelas, Marina Alta, Marina Baja, La Condesa and Cuesta Zapata were evicted – a hundred have already been I’d gone in the days before.
This was stated at a press conference by the technical director of Pevolca, Miguel Ángel Morcuende, who indicated that the so-called ‘colada 7’ is practically stopped because it hardly receives any new material and is located about 120 meters from the sea.
According to the latest data from the cadastre, the Cumbre Vieja volcanic eruption affects 1,196 buildings, of which 963 correspond to residential use, 124 are agricultural, 57 industrial, 27 leisure and hospitality and 10 correspond to public centers plus another 14 for other uses .
In total, with data from this Wednesday, there are more than 825 hectares affected with a lava front of almost three kilometers and 416 people relocated, 47 more than the previous day, with 375 in the Fuencaliente hotel and 41 in the Los Llanos hotel. by Aridane.
Morcuende has also said that the air quality is “reasonably good or regular in the worst case scenario” – this Wednesday the risk thresholds were exceeded in Puntagorda – because there is still a Saharan dust condition but as of this Friday it will be better.
For this reason, it has once again requested the use of the mask and for people with pathologies of the respiratory system, the FPP2.
In addition, the cloud of ash and sulfur dioxide goes to the south and southeast, pushed by the winds, which helps air navigation and does not rule out the arrival of fine ash on the island of El Hierro.
As for rain, there is a meteorological prediction that it will rain on the island this Friday but in areas located to the north and northeast, which avoids a possible added problem in the areas near the eruption since the wet ash could overload the roofs of the buildings and there would be a risk of runoff.
AN INCREASE IN THE INTENSITY OF THE EARTHQUAKES IS NOT DISCARDED
The director of the National Geographic Institute (IGN), María José Blanco, has indicated that the eruption continues with a strombolian mechanism and explosivity index 2, with four pyroclastic emission centers and one of lava.
The ash plume and sulfur dioxide reaches 4,000 meters high this Thursday and the SO2 emission rate stands at 2,700 tons per day plus 663 tons of carbon dioxide, it is on a downward trend.
Regarding seismicity, he commented that it remains stable, at average depths of between 10 and 15 kilometers, although “it is possible” that there are more earthquakes felt and even an intensity of 6 can be reached, with the ability to move and remove objects.
As for the deformation of the terrain, he has said that it follows the same pattern in the stations close to the emission center and points towards deflation in those that are further away.
