The La Palma volcano in the Canary Islands intensifies its activity and adds two new mouths with rivers of lava | International

The volcano on the Spanish island of The Palm, which presents an intense activity this Friday, has two new mouths from which rivers of lava flow that seek to join the original stream in its advance towards the sea.

After these two new mouths were opened during the local morning, about 15 meters apart and 600 meters from the main cone in a northwesterly direction, there are now four lava-emitting centers of the Cumbre Vieja on their thirteenth day of eruption.

According to experts, the new streams, continuously monitored and advancing through a favorable topography, seek to join the first one that arose from the eruption, which, after crossing a road, continues its evolution to lower levels.

In addition, the fall of lava into the sea has generated a lava delta front (“fajana”) that is now more than 475 meters from the coastline, reaches a depth of 30 meters and already occupies an area of ​​27.7 hectares .

The cloud formed by the contact of lava with ocean water and which may contain toxic gases, the so-called “marine plume”, is concentrated in the connection area, according to the National Geographic Institute of Spain.

The air, in healthy limits

Meanwhile, in the Aridane Valley, the area of ​​La Palma closest to the eruption, the air quality is within healthy limits, although, the closer to the eruption area, the parameters change, for what has been established an exclusion zone of a minimum of 2.5 kilometers.

And the fact is that the sulfur dioxide emission rate is 8,700 tons per day.

The Military Emergency Unit (UME, a group of the Spanish Armed Forces in charge of intervening in cases of catastrophe, calamities or serious risks, among others) has also detected specific peaks in certain areas in which those in which the air quality exceeds the levels required, without at the moment there being a risk to the health of the population.

This Friday, the column of ash and gases has reached 6,000 meters in height, without ruling out that it may also affect the northern part of La Palma and that fine ash reaches the island of El Hierro, also in the archipelago of Las Canary Islands, due to a change in wind conditions.

In these thirteen days since the eruption began on September 19, the volcano has emitted 80 million cubic meters of material, alternating strombolian activity (major explosive and launching phases of volcanic material) with effusive activity, in which more magmatic material emerges.

10% of the island affected

The affected area represents 10% of the island, which has an area of ​​just over 700 square kilometers, according to the Volcanic Risk Prevention Plan (Pevolca), so life is normal in the rest of the island, without surprises and only with some problems like ash fall.

In contrast, the thousands of victims of the volcano have lived since the beginning of the eruption in the midst of helplessness, uncertainty and despair.

And it is that the affected buildings reach 1,005, of which 870 have been destroyed, While there are 30.2 kilometers of damaged roads, 27.7 of them destroyed by the passage of lava, and the fallen ash extends over 3,172.9 hectares.

Regarding seismicity, in the last twenty-four hours dozens of tremors have been registered, the largest of a magnitude of 3.5, and located between 10 and 15 kilometers deep.

The tremor level has increased and in some stations near the lava delta it has been of high frequency.
