The lava from the Cumbre Vieja volcano, on La Palma, already affects some 400 hectares and the marine delta (or fajana) that has formed in its fall to the sea It occupies an area of ​​almost 29.7 hectares, according to information updated this Monday by the Department of Homeland Security (DSN).

The partial collapse of the cone structure last night appears to have joined the eruptive mouths of the volcano, which is causing a greater flow of lava outflow, which at certain points reaches almost a kilometer in maximum width.

The ash mainly affects the southern slope of La Palma and it is not ruled out that finer ash particles may reach the island of El Hierro, according to the DSN.

Given the decline in air quality in areas close to the laundry, it was decided to evict the scientific and emergency personnel, as well as the neighbors who went to collect belongings from their homes.

According to this source, the quality of the air in the non-evacuated areas near the volcano’s emission are within normal levels.

On Sunday 16,000 tons of sulfur dioxide (SO2) were emitted, according to the Volcanological Institute of the Canary Islands (Involcan), an amount that could be even higher due to the limitations of measurements made with remote optical sensors type miniDOAS in a land mobile position (with the instrumentation mounted on a moving vehicle), explains Involcan on social media.

The interest in monitoring sulfur dioxide responds to the fact that the emission of this geochemical parameter is “closely” related to the magma emission rate of this type of volcanic systems, adds Involcan.

If a downward trend of this geochemical parameter is observed during the eruptive process, it will be an “unequivocal” sign that the eruption is nearing its end, he explains.

Regarding the provision of basic services, the electricity and telecommunications supply operates normally, but not the supply of drinking water and irrigation, which has been affected in some towns of El Paso and Los Llanos de Aridane.

To guarantee the irrigation of the affected plantations, it is expected that today two portable desalination plants will arrive in La Palma to be installed in the Puerto Naos area and a tanker with a capacity of 30,000 cubic meters has been transferred from the peninsula that will allow to increase the water flow for irrigation.

The National Geographic Institute (IGN) located an earthquake of magnitude 3.7 in Fuencaliente early Monday, about 11 kilometers deep, after a night of high seismic activity.

Another of magnitude 3.4, also early in the morning, located in Mazo at a depth of 13 kilometers, has been felt by the population.

Between the other 3.7 earthquake, located at a depth of 12 kilometers in the southwest of Villa de Mazo, around 8.15 p.m. on Sunday, and the latter, registered at 7.20 a.m. today, the IGN has counted up to 40 tremors, all of them distributed between Mazo and Fuencaliente.
