Teide is having one of its seismic swarms. PEVOLCA experts met this past week and reportedly (Spanish) decided that it would not lead to an eruption. Spain’s IGN goes into more detail in this tweet thread (Spanish).
En Tenerife, esta semana, se ha registrado el noveno enjambre sísmico desde 2016.
Ante este aumento de actividad, los científicos examinan lo que está pasando debajo del pico más alto de España

I can’t yet understand a word of spoken Spanish, so I can’t explain what he’s doing with the balloon. I suspect he might be illustrating the release of gases and fluids that could be causing this Teide swarm, rather than magma movement causing it.
This repost is now also the Tenerife update page.
Updates will be beneath the original post text, and here are some information links:
- Spain’s National Geographic Institute (Spanish)
- Toulouse VAAC
- Global Volcanism Program page
- Last but not least, this X account is an unofficial but excellent source of information on Canary Island volcanoes. The link is to their information page, and it’s worth visiting even when no eruption looms!

🌋🌋🌋
Original guest-video post from 2021:
Instead of stressing over the hazards of Cumbre Vieja on La Palma Island, let’s go to another of the Canary Islands — Tenerife — and watch the moon set behind tourists who have climbed up Teide Volcano (highest peak in the Atlantic area) to watch sunrise.
Per APOD, the moonset, while done with telephoto lens, is filmed in real time.
The Canary Islands may have formed from a mantle-plume hotspot, like the Hawaiian Islands, which of course are way out in the Pacific Ocean.
The Canaries, on the other hand, sit very close to Africa’s western coast, which makes their origin controversial.
But all that volcanism, at latitudes where the weather is spring-like all year round, make for some gorgeous scenery.
Take Tenerife, for instance:
It’s a volcanic jumble!
Updates
February 23, 2026, 1625 UTC: Per X translation: “Since last night, at midnight, we have had a new swarm, a bit stronger, on the order of a thousand events in the western area of Las Cañadas, and it still hasn’t finished.”
“We hope that if an eruption is going to occur, especially a basaltic eruption like the one we experienced in La Palma, it will be preceded by strongly felt earthquakes, much faster deformation, and right now we are not seeing that. We must stay alert because this can change.”
"Desde anoche, a las doce, hemos tenido un nuevo enjambre, un poco más fuerte, del orden de mil eventos en la zona oeste de las Cañadas, y todavía no ha terminado"
"Esperamos que si se va a producir una erupción, sobre todo una erupción basáltica como la que vivimos en La Palma,… pic.twitter.com/by7uU3lNp9

Also this, reposted by IGN: X translation — Stavros Meletlidis, volcanologist, on the latest seismic swarm at Teide:
🗣️”We see it as more energetic; the source is magmatic fluids; prediction is impossible, we analyse patterns; we ask the population to get information from official channels”
Stavros Meletlidis, vulcanólogo, sobre el último enjambre sísmico en el Teide:
🗣️"Lo vemos más energético; la fuente son fluidos magmáticos; la predicción es imposible, nosotros analizamos patrones; pedimos a la población que se informe por los canales oficiales"
