The new lava flow from the volcano and the change in wind orientation generate new concern on La Palma

The third week of the eruption of the Cumbre Vieja volcano, whose lava already affects an area of ​​525.77 hectares (33.02 more than the previous day), keeps the emergency services very aware of the new lava flow that runs north of the main one, because it can destroy areas that had been safe in the first days. There is also concern about the change in the wind, which threatens to make La Palma airport inoperative again.

Despite the new collapses of the cone, it is not expected that the new lava flows will change the trajectory that they are already following on the surface.

Seismicity continues to be high. It is kept in medium depths (10-15km) and deep (more than 20km). The current level of seismicity suggests that more felt earthquakes will continue to occur, which can cause localized landslides in sloping areas. Tonight, the largest earthquake occurred at 10:46 p.m. (Canary time), 4.3, in Villa de Mazo, but with the focus at very deep levels, 39 kilometers away.

According to the latest report from the Department of National Security (DSN) of the Government of Spain, three weeks after the start of the eruption, the emission centers of the crater are still active.

The constant effusive activity has expanded the flows to the north, continuing its descent towards the Todoque area, which had not been affected by the main flow.

Thus, there are currently two branches in the north stream: the south, which has joined the previous stream, and the north, which is located in the Los Llanos de Aridane industrial estate.

The latter is the object of special vigilance due to the possibility that its route may vary. And it is precisely in that area where the neighbors have returned to spend another hard night, due to the uncertainty of the laundry, but also due to the continuous noises and explosions.

According to the European Copernicus service, there are 1,281 buildings affected. Regarding the cultivated area, there are 132 hectares with damage.

Regarding the ash column, it reached a height of 3,500 meters this Sunday. Despite the improvement in the meteorological conditions of the last hours, this Monday a turn to the west component of the wind is expected between the levels of 2,500 to 5,500 meters, which will cause a displacement of the ash plume that could affect the operation of the La Palma airport.

The emission of sulfur dioxide (SO2) continues to register high values, consistent with the eruptive process, and far, for the moment, from the maximum permitted thresholds in terms of air quality.

And as for the lava delta or fajana, it continues to extend its surface and advance in the depth of the sea until its front is placed on the head of a marine canyon. However, the estimated calculation of its surface has been corrected and it has been set at 34 hectares, compared to previous measurements that approximated it to 40 hectares.
