The volcano of La Palma It’s been five weeks eruption at full power. Far from sending, yesterday added a new clothes and a leak open under the secondary cone, from which flows abundant liquid lava, and in which earthquakes have been constant.
Carmen Lopez, responsible for the volcanic surveillance network of the National Geographic Institute (IGN), points out that it is still too early to know how this new emission center will behave in the future, if a new cone will form, or if it will be a leak through which lava will come out. more liquid, like others opened previously.

The emission of more fluid lava makes it advance downhill with higher speed, on existing castings.
López indicates that yesterday an increase in the signal of the tremor, until reaching a culmination point that coincides with the appearance of this new emitting center. From there, it dropped notably.
A considerable increase in seismicity and explosiveness has also been registered in the last few hours, with several sonic bombs.
There has also been a considerable increase in the number of seismicity It’s from explosiveness, with several sonic bombs, until the opening of the new hole in the volcanic building in Cumbre Vieja.
In this regard, Carmen López highlights that the volcano “needs a lot of energy” to find new ways to get out of the lava and that, by releasing the excess pressure and maintaining a constant flow, this explosiveness disappears.
For the rest, note that the volcano usually experiences its most substantial changes at dusk or dawn. According to some colleagues, he behaves like “a child who gives bad nights”.
Concern on several fronts
There are several fronts that have occupied and worried scientists and the management committee of the Canary Islands Volcanic Emergency Plan (Pevolca).
The washing front stopped at the La Laguna Neighborhood, but it continues to receive inputs in its rear part that sooner or later will end up advancing towards the sea. To this is added another that worries: the clothes that come out of the mouth that until now only emitted pyroclasts.
This new cast advances about 50 meters per hour, according to calculations of Geological and Mining Institute, and goes to the Corazoncillo area, in Las Manchas.
The crisis cabinet’s hope is that this wash will end up joining a previous one and not cause damage, only material, as that area was one of the first evacuated since the volcano began to erupt on 19 September.
There are currently four active emitter centers that contribute load to the washes
Furthermore, they are confident that the abundant accumulation of ash in that area slows down and contributes greater viscosity to that garment.
Currently, there are four transmission centers that contribute to the charge of the flows, and throughout the eruptive process there were ten, some of which were activated and closed.
The scientific committee analyzes the “notable increase” in seismicity at different levels. He also notes the “slow trend” of terrain deflation at points distant from the eruptive center, while the deformation near the cone remains stable.
The Copernicus system publishes its thirtieth eruption report
The European Satellite System Copernicus updated its diagnosis of the devastating effects of lava from the Cumbre Vieja volcano, with a second measurement taken yesterday that raises the burnt surface already 2,146 destroyed buildings, which means an increase of another nine hectares buried by lava in a nine-hour margin.
Our #RapidMappingTeam released its 3rd updated map
It is based on COSMO-Skymed NG radar images
From October 24th at 07:14 UTC:
▶ ️ Lava flow extension: 901.2 ha (+9.3 ha in ~ 24h, from a new external flow)
▶ ️ 2,146 buildings destroyed (+3) pic.twitter.com/sWlRNgynGe– Copernicus EMS (@CopernicusEMS) October 25, 2021
In the thirtieth mapping carried out by Copernicus since the beginning of the eruption, it appears that in addition to the destroyed ones, there are others 128 partially or possibly damaged buildings, without distinguishing between residences and other types of use.
According to data managed by the management committee of the Canary Islands Volcanic Emergency Plan (Pevolca), with registration data updated 48 hours ago, there are just over a thousand houses destroyed, in addition to implement rooms, hotels and restaurants or leisure and buildings for other uses.
Copernicus estimates 69.2 kilometers of roads affected by the runoff, of which 65.7 have already disappeared. The number of people housed in hotels is 439, in addition to another 46 dependents housed in social and health centers.
