Cumbre Vieja In the 'black valley' of La Palma: "Run away, the gases from the volcano are coming!"
The
temporal evolution
of the chemical composition of the volcanic plume of the
Cumbre Vieja
volcano
, on the island of
La Palma,
reflects a downward trend in the relationship between carbon and sulfur, which indicates that the magmatic contribution has a more superficial origin.
The national director of Volcanic Surveillance of the National Geographic Institute (IGN) and spokesperson for the Pevolca Scientific Committee, Carmen López, explained this Monday that all the observables indicate that the deepest part of the volcano's feedback system is being "less active" and it has "less capacity to nourish magma, that is, to fuel the eruption for longer."
Carmen López added that there are also signs that
this feedback system "is loosening"
, such as lower seismicity or deflation, coupled with the fact that these reservoirs are becoming smaller, which suggests that the available magma is closer to the surface.

In the 'black valley' of La Palma: "Run away, the gases from the volcano are coming!"
An endless caravan of cars, vans and pick-ups awaits early in the morning on the outskirts of Fuencaliente, at the southern tip of La Palma.
Passengers drain thermos of coffee and homemade sweets while they wait for the authorities to loosen the controls of the
exclusion zone
for a few hours
.
The Sunday plan has changed since the Cumbre Vieja mountain burst: the copious family barbecues with views of the sea have become express visits to the houses to collect belongings and protect them as best they can from the fury of the eruption.
