The main cone of the La Palma volcano has suffered in the late evening of this Sunday a partial collapse of its structure while the effusive activity has increased, with the emission of fluid lava, reported the Volcanological Institute of the Canary Islands.
According to information provided by the forward command post, the partial collapse occurred around 9:10 p.m. and, apparently, some of the eruptive mouths have joined.
There is a greater flow of lava outflow, but it runs through the same channel that had existed until now and at the moment no new affectations have been observed for this reason.
Carmen López, from the National Geographic Institute (IGN), explained to Efe that throughout the eruptive process there have been and episodes of this type will continue to be produced.
And he has referred to the images that the drones that fly over the cone will provide in the next few hours to determine with more attitude if that lava comes from the leaks or from the cone itself, whose activity is eminently Strombolian.
Already in the morning it advanced that the morphology of the cone is constantly changing and that in the last hours it had been observed more widening and plugging.
The latest data provided by the Copernicus satellite indicates that there would be 1,074 buildings affected by the volcano eruption from Cumbre Vieja, 946 of them destroyed and 128 damaged, when two weeks after the eruption.
There’s also 33.2 kilometers of roads that have been disabled on the LP-2, LP-212, LP-211 and LP-213 roads, while the extension of the drain is already 397.5 hectares.
Also, this Saturday la wash has broken the last irrigation connection that existed in the town of El Remo, that supplied water to some 600 hectares of banana plantations. In the coming days, the installation of portable desalination plants and tankers will begin.
New aid package of 200 million
Sánchez has stated in La Palma that it is a “very powerful” plan that will be approved as a royal decree by the Council of Ministers to be held next Tuesday.
These aids add to the 10.5 million for housing and basic necessities approved by the Executive last week, when it also declared the island as a catastrophic zone.
Sanchez has made the announcement of this new economic item on his return to La Palma, where he plans to visit this noon to people temporarily staying in a hotel in Fuencaliente, in the south of the island.
Thousands of years evolving
The data obtained by scientists from the magma of the volcano indicates that it contains large amounts of tephrite, which indicates that it has been evolving under the island for thousands of years.
The geologist and professor at the University of Las Palmas de Gran Canaria (ULPGC), José Mangas, explained on Televisión Canaria that two days ago the composition of the magma that is rising to the surface was known: a tephritic magma.
José Mangas has pointed out that this means that a primary magma is not coming out of the mantle, that is, it is not the partial fusion of the mantle that is under La Palma that is coming to the surface.
The geologist has pointed out that this magma has been under the island for thousands of years evolving in a chamber in the upper part of the upper mantle and a little oceanic crust, so it would be a “son magma” and not a “father or mother magma”, which has basaltic compositions.
Mangas pointed out that the latest historical eruptions on La Palma have also been tephritic (San Juan, Teneguía, El Charco, etc.). Later, In the last 300 years, the magmas that have come out of La Palma are colder and richer in silicon, sodium and potassium.
Regarding the possibility of new islands being generated as a result of this eruption, José Mangas has totally ruled it out. “That makes no sense,” said the geologist, who assured that there will be new islands because La Palma, like the other islands of the Archipelago, are volcanic buildings that have needed millions of eruptions like the current one to form.
Regarding the irrigation problems that the agricultural sector is suffering, Ángel Víctor Torres reported that the Canarian Executive has allocated 4 million euros to the acquisition of two portable desalination plants. In the event that the water quality was not sufficient, the hotel’s water in Puerto Naos and other desalination plants would be used. Likewise, the Government of Spain has arranged a tanker with more than 30,000 m3 of capacity that will set sail from the Peninsula in the coming days. It is also considered that the Kamov They can carry water from reservoirs outside the affected area to supply water for irrigation.
Along with it, this week there will be meetings to face the problem of road infrastructures by the Minister of Public Works, Sebastián Franquis, to arbitrate emergency mechanisms to be able to connect with Los Llanos de Aridane.
