But how stable is it?

Would you be able to build on it?

I wouldn't have thought fresh lava land deposits would be structurally sound. So while it's new land it may not be of "value"

No idea how stable it is...

I read somewhere that the La Bombilla area highlighted in yellow was new land formed in a similar way, but I can't find the link at the moment.

(lava from the current eruption is entering in the area highlighted in red)

Current lava flow the bit in middle is a large hill that the lava is snaking around on the way to the sea . The very top branch of the flow is kind of a worry because that heads into a fairly heavily populated area with a lot of houses and a lot of agricultural land . The hope would be it turns down towards sea and not continue towards Tazacorte

good pic.

ah yes, you can see the snaky track the lava took in the darker colour to form the new Bombilla land - and it seems to be a fair whack of land too

Lava from the side vent appears to be finding a new path atm to the left of the current channel as we see it. First sign of change there for a couple of days.

Where you watching this ? I’ve lost the video

Here you can see part of the lava flow in the last half hour now in to a new channel to the left of where it was atm,

Kermit.de.frog

Hard to tell whether that new channel is just overflow from inundation of lava in the existing channel but could be very significant downstream and may put more properties at risk.

Kermit.de.frog

New vent just opened right on top of side vent. Lava emerging and completely different direction of travel. Let's how that evolves.

Present lava vent appears to be putting a lid on itself which may mean extra pressure in other spots for lava to emerge.

The Cumbre Vieja volcano, on the island of La Palma, not only maintains the same fierceness after the arrival of the lava into the sea, but in the last hours it has increased its explosiveness and the ash fall, as confirmed by sources from the Institute. National Geographic (IGN). They warn that explosions are being generated on the north slope of the main cone. This new situation could cause collapses in the cone in the short term, something that enters into the forecasts of the scientists displaced to the island. In this sense, the volcanologist from the National Geographic Institute María José Blanco explained this Thursday at a press conference that the morphology of the cone "has changed and may continue to change."

Kermit re new lava streams outlets...lets hope they join back up with the earlier ones downhill before it hits what's left of the town

25% of the houses lost... happened in the last 24 hours :(

Kermit.de.frog

New vent opening now. This could be bad depending on where the lava goes. It looks bad in general. Multiple vents.

pad199207

Indeed. See that now

Serious pressure coming out of that main vent

Kermit.de.frog

Lava out of latest vent becoming less viscous.

Probably see a new fountain there imminently?

Kermit.de.frog

Looks like the engine is coming to rest again.

Kermit.de.frog

A potential entire new opening has just emerged far away from existing activity. It's the bottom left hand corner here...serious development potentially.

https://m.youtube.com/watch?v=TiRBJNaLkHk

Edit: Big plumes of smoke emerging there and the glow suggest there is lava at the surface. A second opening down there now. Oh dear.

speckle

not looking good...big balls of lava rock now also being spit out further to right. Possibly undermining of a big chunk? hope it stabilizes and stays put til tommorrow/daylight.... smoke coming from 2 places either side of that new lava stream at bittom of screen from earlier. Dogs were barking loudly earlier tonight...they seem to sense things there. More people allowed collect stuff yesterday..hopefully the areas this might effect. hopefully air still ok for areas asked to stay inside. fingers x'd.

whooah large fountain expolsion from top vent.

Kermit...thats like the lava reached something at that point very combustable? Or a new vent? Or both?

Saying possible gas cylinder this morning.

Hard to tell from TV stream this morning but seems to be Multiple new lava flows

Oh! Copernicus updated early this morning. It had been quite behind the progress of the lava, but they managed to generate some imagery twice in 12hrs.

Our sister planet Venus has residual rotation, no spherical deviation between polar and Equator diameters, no plate tectonics, but has the largest volcanic activity among the inner planets.

The Earth has a rapid rotation, 26 mile spherical deviation, a very dynamic surface crust and volcanic activity, mostly along the crustal boundaries but also in the centre of the plates, Haweii for instance.

When I proposed differential rotation across latitudes almost two decades ago to account for the symmetrical generation of crust off the Mid Atlantic Ridge, the reaction wasn't rejection, but rather they carelessly threw the kitchen sink at the underlying rotational dynamics which mesh the spherical deviation with plate tectonics. People can still see the mess when it entered the Wikipedia article on plate tectonics.

Would love to post imaging, however, the petty people who prevent this in this forum have seen to it that is not possible.

For those who do care, the planetary comparisons work and may I remind people that Alfred Wegener was a meteorologist who used reasoning from all sciences to create a narrative that was rejected by geologists-

“Scientists still do not appear to understand sufficiently that all earth sciences must contribute evidence toward unveiling the state of our planet in earlier times, and that the truth of the matter can only be reached by combing all this evidence. ... It is only by combing the information furnished by all the earth sciences that we can hope to determine 'truth' here, that is to say, to find the picture that sets out all the known facts in the best arrangement and that therefore has the highest degree of probability. Further, we have to be prepared always for the possibility that each new discovery, no matter what science furnishes it, may modify the conclusions we draw. ”― Alfred Wegener

Oh christ orion has been summoned.

Kermit.de.frog

Hard to know how things stand in the morning with the light and angle of the sun. Can't see whether the lava flow at the base continues but the mere fact lava emerged there this morning must be alarming locals and no doubt more properties have been lost there.

Have to wait for a clearer picture.

spain are an hour ahead of us but sometimes I look at the live feed at 9am Irish time and it looks really really dark on live feed. Strange

Someone pointed out earlier the Canaries are the same time zone as us!

That's correct. Mainland Spain is 1 hour ahead of us but the Canary Islands are in the same time zone as us/Ireland. The Canaries are also a fair bit further west than Ireland so sunrise/sunset times are later than Ireland. For example, the sunrise times for Santa Cruz, La Palma Vs Dublin today are 08:04 Vs 07:26 and for sunset it is 19:56 Vs 19:01
