The National Geographic Institute (IGN) has measured “very high” concentrations of sulfur dioxide (SO2) in the southernmost craters of the Cumbre Vieja volcano, despite the fact that almost eight months have elapsed since the end of the eruption.
The IGN reports these measurements on social networks, as well as the presence of fumaroles “with a high content” of water vapor, which, it clarifies, “is common” in this posteruptive phase.
A few days ago, both the IGN and the Volcanological Institute of the Canary Islands (Involcan) and the Geological and Mining Institute of Spain (IGME) published videos on the Internet showing holes in the ground with incandescent lava in locations near the casing, at very little distance. depth.
At certain points the temperature reached 1,000 degrees Celsius.
To this we must add that one of the interior walls of the crater of the new volcano has registered a landslide, according to Involcan on their social networks. The collapse, he points out, was discovered on Monday afternoon during the “routine work” carried out by the institute at the site. Likewise, he explains that “these phenomena are normal due to the settlement of the ground.”
