Spain: Lava gains ground from the sea on La Palma and deterioration of the air is expected [VIDEO]

The lava emanating from the Cumbre Vieja volcano from the island of La Palma (Spain) falls into the water in a continuous flow and this Thursday continues to gain ground from the sea, while a deterioration in air quality is expected due to changes in the winds.

For this reason, experts ask the population closest to the volcano to take extreme precautions, especially as of Friday, and in the town of Tazacorte high values ​​of sulfur dioxide have already been measured – above the regulations on quality of the air, although without posing a health hazard – and there is the smell of rotten eggs.

In this municipality, where on Tuesday the lava flow from the volcano Old Summit reached the sea, 500 micrograms of sulfur dioxide (SO2) per cubic meter have been punctually measured, although this level has already dropped to 300.

Now it is considered that the problem can extend to Los Llanos de Aridane (the values ​​are around 100 micrograms per cubic meter) and El Paso, so special precautions are recommended: stay indoors, unless necessary, and use FFP2 masks, especially people with respiratory conditions, the elderly, children and pregnant women.

This increase in measurements coincides with an increase in SO2 emissions from the volcano, to 7,149 tons per day, a relatively high value.

A continuous waterfall of lava into the sea

Meanwhile, the magma flows into the ocean in a continuous flow, falls in the form of a cascade and has created at the base of the cliff a delta with a wide front that has reached the level of 24 meters in marine depth, according to the National Geographic Institute of Spain.

Since the lava reached the sea, the main stream has “some stability”, with “overflows in some points” and “some finger that has separated from the main axis”, but the trend is towards channeling the magma, according to the Volcanic Emergency Plan of the Canary Islands (Pevolca).

And in the area of ​​contact of the magma with the water, a cloud of water vapor and possibly toxic gases forms, a “marine plume” that, for the moment, is concentrated in a small area.

Although the eruptive process continues its activity, the rest of the flows are practically inactive, although since this morning the appearance of a fumarolic field has been observed on the northeast flank.

The stability in the laundry has allowed farmers to access their farms, feed their livestock or that evacuees could go home for urgent reasons to collect something.

People evacuated by the activity of the volcano of Old Summit They are at around 6,000, while confinement is maintained in the towns of San Borondón, Marina Alta, Marina Baja and La Condesa, as well as the 2.5-kilometer exclusion zones around the volcanic cone and 2 nautical miles.

Faced with this situation, the regional government of the Canary Islands archipelago has approved a decree law with tax exemptions for those affected, such as a “zero” General Indirect Tax on the Canary Islands (IGIC) on the purchase of real estate, land and vehicles and the forgiveness of equity and donation and inheritance fees.

Almost a thousand buildings affected

According to the latest data from the European Copernicus terrestrial monitoring satellite system, since the volcano erupted on September 19, lava has covered 338.3 hectares, including the land that has gained from the sea since the night of the 28th, while the ash spans 1,752.8 hectares.

There are already 981 buildings affected, 855 of them destroyed, and damage to 29.8 kilometers of roads, of which 27.4 are devastated. The current height of the ash cloud is 5,000 meters above sea level.

Regarding seismicity, Pevolca experts indicate that it remains in the same area as previous days and at depths of more than ten kilometers, with a 3.3 magnitude earthquake with intensity 2 as the maximum measurement, and there are also movements more superficial around the core of the eruption.

The tremor is stable, although in some areas close to the cone it is of high frequency and the deformations maintain a stable pattern.

The National Geographic Institute has located eighteen earthquakes in the southern part of the island, four of them felt very weakly by the population.
