The reactivation of one of the lava flows that flow from the Cumbre Vieja volcano, on the Spanish island of The Palm, brought the magma flow closer to just 300 meters from the sea, so it could, if it does reach the ocean, create a new lava delta.

Another of the lava flows from the volcano that has erupted since last September 19, reached the coast nine days later and was forming a delta or “fajana” that already has an area of more than 34 hectares according to the latest calculations.
Now another stream, the one that runs from north to west after the lake of lava overflowed Cumbre Vieja volcano it approaches the sea in another area of the island called Playa del Perdido, where the phenomenon could be repeated.
This arrival at the sea would be positive for the lava to drain and produce the least impact on land, according to Miguel Ángel Morcuende, technical director of the Canary Islands Volcanic Emergency Plan (Pevolca), the body that oversees the eruption of the volcano.
The scientific spokeswoman for that same institution, María José Blanco, said today that according to estimates obtained by satellite until yesterday the volcano had already emitted a volume of magma of about 75 million cubic meters.
CONCERN ABOUT ASHES
In addition, the height of the ash and gas plume has increased to 4,000 meters and for at least the next 72 hours its position may affect operations at La Palma airport, as happened last week, when it was inoperative due to the ashes.
“The weather forecast is bad”, Morcuende pointed out, because the west wind pushes the ashes to the east of the Canary Island and the thermal inversion makes its dispersion difficult.
The authorities consider, on the other hand, unlikely that the cloud will reach the Tenerife North airport, which has much more traffic.
For now, the air quality in the municipalities near the volcano remains “reasonably good”, with values of sulfur dioxide below the alert threshold of 500 grams per cubic meter, except in a punctual measurement at dawn that reached 830 and then subsided.
Only the entry of the lava into an industrial estate and the consequent combustion of a cement factory, advised the confinement of the 3,000 people who live in the closest areas in their homes as a preventive measure, pending the evolution of the measurements of air quality.
THE NEW WASH MAKES THE AFFECTED AREA GROW
The new flow to the north means that in the last 24 hours there has been the greatest daily advance on the surface affected by the lava, more than 10 percent, although always within the exclusion area that was marked since the beginning of the eruption and from which all its inhabitants were evicted.
The latest measurements indicate that the affected area is 591.1 hectares, 65.33 hectares more than on Sunday, and the maximum width of the flow is 1,520 meters.
The affected buildings are already 753, of which 620 are homes, 70 implement rooms where agricultural tools are kept, 29 for industrial use, 19 for leisure and hospitality and 15 other buildings such as schools or dispensaries.
In the crops, there are 150.01 hectares affected, of which 74.82 hectares of banana trees, 45.16 of vineyards and 8.78 of avocado trees.
Regarding seismic activity, the number of tremors continues to increase, the maximum of magnitude 4.3, in an area slightly further south than the swarm that began before the eruption and always at medium or high depths, the most numerous among the 10 and 15 kilometers.
In the lava delta formed days ago and that continues to grow, the marine plume of gases released by the contact of the lava with the ocean water is very weakened along the entire edge.
In any case, if the delta continues to advance due to the contribution of more lava from the volcano, partial collapses could occur that would generate waves, hydromagmatic explosions and gases, but always in that environment.
