The eruptions of the Cumbre Vieja volcano in the Canaries have reached the Atlantic, as was feared. This arrival of lava in contact with ocean waters is worrying because it is accompanied by the release of toxic gases and at the very least dangerous and unpleasant to breathe. It also extends the island of La Palma, a phenomenon well known for volcanic islands. A third eruptive mouth has just opened with a spectacular new flow.
The hot spot of the Canary Islands continues to supply below. In the Canaries, on the island of La Palma, the volcano is said to have destroyed 400 million euros of infrastructure, and no one knows when the eruption will end, but there is good news. constructions The Instituto Geológico y Minero de España New images of the flows including the one that started this night. The new eruption filmed at night. What probably concerns the authorities the most is the possible effects of gases Lava from the Cumbre Vieja volcano continues to accumulate in the ocean, the surface of the island of La Palma increases. European Copernicus satellites , the language of igneous rocks resulting which we observe already measures nearly 338 hectares, illustrating by what mechanism islands can reach the ocean. Hawaii Fortunately, for the moment, the winds are carrying away the gases of this language and, outside the safety exclusion space defined by the authorities, banana growers can harvest or water the plantations.

This arrival of lava in contact with the waters of the Atlantic is worrying because it is accompanied by a release of gas toxic and at the very least dangerous and unpleasant to breathe. Since September 19 we have been witnessing a specta eruption cular on the island of La Palma in the Canaries. She would undoubtedly have driven the youngster The lavas of Cumbre Vieja degas at sea and cause the formation of water vapor plumes. © Euronews (in French) As we explained in one of the previous articles below, By consulting the records of the island’s eruptions, one can expect that of Cumbre Vieja to last from 24 to 84 days. However, its lava has just reached the sea, which is potentially worrying although not catastrophic. Lava thus reaches the Pacific Ocean, often in Hawaii for example. As also explained in the video of Euronews, above, the Cumbre Vieja flows reached the sea this night on Playa Nueva beach. In response, the local authorities declared an exclusion zone at sea with a radius of more than three kilometers and invited some of the inhabitants of the island to stay at home. Sea water containing in particular chlorides, we know that thermal shock with lava at more than 1,000 ° C will not only produce white clouds of microscopic droplets of water but also hydrochloric acid which is dangerous for people already suffering from respiratory problems.

The flows are progressing towards the sea, which worries the authorities of this island which is part of the Canary Islands archipelago in the Atlantic. However, no worries about the cloud of sulfur dioxide going back over Europe and France. There is still no reason to think that we should fear a devastating tsunami caused by a For the first time, flights have been canceled, one from Madrid, the other six to neighboring islands, due to the large ash cloud released by the Cumbre Vieja volcano. liquids acids may irritate the skin, The Lava Encounter at more than 1,000 ° C with the sea at 20 ° C would produce a thermal shock generating not only columns of water vapor charged with hydrochloric acid but also small particles of volcanic glass as a result of the reaction between the lava and Seawater.

The lava flows of the Canary Islands volcano continue to carry everything in their path down towards the coast of the Spanish island of La Palma, where their arrival is feared because of the possible emission of toxic gases. © Euronews Toxic gases, it also emerges at the level of the eruptive mouth of Cumbre Vieja as explained on its page Facebook the Instituto Volcanológico de Canarias Satellite data allow us to estimate that the area affected by the lava flows of the current eruption exceeds the 154 hectares. The question arises as to how far the flows will go, which supposes being able to estimate for how long the eruptive activity will continue. Still on his page, the Instituto Volcanológico de Canarias The sulfur dioxide cloud is expected to fly over the south of France this Friday, September 24.

Article by Laurent Sacco published on September 20, 2021 The Cumbre Vieja volcano in La Palma has just erupted. While many images show the lava fountains and flows emitted by the 20 years ago, the geologist and geophysicist Simon Day and Steven N. Ward published in Geophysical Research Letters an article – which was to generate much ink – in which the two men claimed that the western flank of the Cumbre Vieja volcano in La Palma is unstable, and that ‘a landslide could occur. megatsunami capable of causing very significant damage on the other side of the Atlantic in particular was to be feared. Let us recall that the island of La Palma is part of the Canary Islands archipelago which is a series of islands approximately aligned along a west-east axis, and which extends to the north-east by a series of mounts hotspot. La Palma is subject to substantial seismic and volcanological monitoring because there is a stratovolcano on which there is an active volcanic fissure at the level of the Cumbre Vieja Cumbre Vieja, a volcano located in the Canaries, has erupted. But, precisely, the seismic activity since September at the Cumbre Vieja volcano worried volcanologists. The concerns of the researchers proved to be justified because this Sunday, September 19 an eruption did indeed begin at Cumbre Vieja at 3:15 p.m. local time (2:15 p.m. To obtain a fairly accurate French translation, click on the white rectangle at the bottom right.

So that the flank of Cumbre Vieja manages to meet conditions close to the instability, it would simultaneously require a earthquake of magnitude exceptionally high and a large-scale explosive volcanic eruption … the probability of an eruption with a high explosive rate and both of a large The eruption of the Cumbre Vieja volcano on the island of La Palma in the Canaries threatens the tourist coastal areas which have been evacuated.

Article by Michel Olagnon, Ifremer, published on 01/18/2005 Following the tidal waves of tide devastating December 26, 2004, the question of the danger of encountering tsunamis in the Atlantic has resurfaced. In particular, questions are raised about the possible collapse of the Cumbre Vieja volcano in La Palma in the Canaries. The following few lines present my personal analysis of this affair. In September 2000, researchers at University College London contacted the British Minister of Science Lord Sainsbury to warn him that the collapse of a volcano in the Canaries could send a The western flank of the Cumbre Vieja volcano in La Palma is undoubtedly unstable, but half a dozen top eruptions can still occur before it collapses (Prof. Bill McGuire).
