10/10/2021 h Canary Islands.- PALM ISLAND ERUPTION.- CONE COLLAPSES, NEW COLLADES, ENGULLING EVERYTHING THAT PILLS, THE VOLCANO IS UNLEASHED AND WHAT IS MISSING..- In the next video, a visual summary of what this volcano is messing with, I don't really know where to start.

Well yes, most urgent, cyclical patterns, 35 hours ago we had an Earthquake magnitude 4.2 and 37 hours before a magnitude 4 3... or what's the same, the possibility of the Earthquake I said was going for the early morning at 2:10 h Canary Island has been delayed to this maximum, despite everything yesterday we had a late moderate one and everything but not the one I expected.

Yesterday was dropping very well energy, with many earthquakes of 3 and almost 4 with a swarm of spasmodic tremor and signs of gas depressurization... but these last few hours has been quieter, less earthquakes and indicating that it has possibly been encountered another obstacle so you must be pressurizing and reserving the energy to jump harder..

The forecast for today is that we will pass another hour maximum at 13:35 h IGN, 14:35 h Canary Islands, 15:35 h peninsula. and then tonight last midnight at 2:00 h IGN, 03:00 h canaria 04:00 h peninsula time. We'll see what happens, but as I say, I see it very active the swarm volcanic Earthquake under the island and I don't rule out that we have earthquakes in the 4.4-4.6 environment with this energy emission rate.

EDITED: If I notice the Earthquake earlier, it comes forward for a while or it will do in several.. a 4.1, which was initially a 4.2 to 22 km under Old Summit. Don't trust yourself.

It gives me that this volcano is like a rumbly boy who when he shuts up is that something prepares.

Temperatures of 1240°C have been measured in volcano's flow that continue to flow through the north side of the field of flow. Lava flow has buried and ravaged all the houses left north of Todoque. In the photos of 10:00 h today from a drone, it looks like the front of fluid and very hot laundry that was bordering the field of flow on its north side has passed Todoque (9 B flow) and is heading to the ocean, being the front more or less north east - north of the mountain of Todoque. As for the other flow that was killing the polygon (flow 9 A) continues its progress more slowly, but is well fed and progressively and is about 300 m below the campgrounds path and 1 km away still from General LP-2. E n when I have the map ready I put it to you.

And what to say about the videos there is... yesterday a huge block appeared in several videos dragged by a lava channel between houses... it's awesome.

Last time I finish with deformation, where LP03 goes down a bit and LP04 and MAZO goes up a bit.. we stay the same, but it can be interpreted as swelling from the south and east (by the swarm in depth) and sinks on the north (eruption zone)

The tremor instead remains more or less stable,, a little wing, that if lower than the first days of eruption, because it has cleared the throat (the ducts of the dam) and removed the water in good part of the journey with a steam seal with a magma so hot.

We'll see what happens, but this goes on and there are two things, the volcano or eruptive point and the swarm or magma very pressurized looking for where to come out, most likely to do it by the open channel of this eruption... not though other possibilities have to be ruled out. (Enrique)

The change in wind direction could affect air traffic in Tenerife tomorrow
This wind turn will cause a displacement of the ash plume and sulfur dioxide from its current position with a north-south configuration to a west-east distribution throughout Monday.

EUROPA PRESS10/10/2021 · UPDATED 15:12


The calculations of the amount of lava emitted by the La Palma volcano vary between 39.6 and 60 million cubic meters (m3) depending on the measurement system used, a variation that highlights the difficulty of having a exact figure.

This was made clear this Sunday during the press conference after the Scientific Committee, which was attended by the technical director of the Canary Islands Volcanic Emergency Plan (Pevolca), Miguel Ángel Morcuende; and the director of the National Geographic Institute (IGN) in the Canary Islands, María José Blanco.

Precisely Blanco pointed out that Involcan stated in today's meeting that the value of the magma expelled from sulfur dioxide emissions reaches 39.6 million cubic meters.

On the other hand, to highlight the difficulty of reaching an exact data, he observed that the estimated value through a satellite measurement raises the figure to about 60 million cubic meters. "There is a dance of figures that at this time it is not possible to confirm," he clarified.

VARIATIONS IN WIND DIRECTION

On the other hand, the director pointed out that this Sunday the prevalence of the north component will continue but as of this Monday, between 07:00 and 13:00, a western component turn is expected.

This turn of the wind will cause a displacement of the ash plume and sulfur dioxide from its current position with a north-south configuration to a west-east distribution throughout tomorrow.

"The expected changes in the wind regime - he continued - may affect the operation of La Palma Airport starting tomorrow and it cannot be ruled out that it will also affect the airports in Tenerife".

AIR QUALITY IS REASONABLY GOOD

In this regard, the director of Pevolca has explained that the air quality on La Palma is reasonably good as the maximum thresholds for sulfur dioxide and the size of the suspended particles are not exceeded.

In total, he explained that the area affected by the volcano is already 525.77 hectares –33.02 more than yesterday–; that the maximum width after the rupture of the northwest cone this night amounts to 1,520 meters; and that the strip occupies about 34 hectares of land.

In addition, Morcuende explained that of the 1,281 infrastructures damaged by the lava, 1,186 have been destroyed and 95 have suffered damage.

SEVERAL WASTE

On the runoffs, after the destruction of the cone, several of these new emissions have taken place, the one located further to the northwest being practically braked.

Meanwhile, the second one that is more to the northwest has activity and two branches; the north branch, which is at the height of the Cementera, advances at about five meters per hour - a minimal advance. "But we are monitoring it because it can reach the head of a mini-basin and vary the route, which could create some complication that would entail taking new civil protection measures," he said.

Finally, in the lower part, the other branch has already passed the LP-213 road and the forecast is that it will go parallel to the previous one and look for an exit in the north of the Todoque mountain pushing the old arm that has been stopped for days .

Informative Update: Since September 10, 2021, the Canary Seismic Network has detected on the island of La Palma almost 35.000 earthquakes, of which 2984. have been able to be located. The maximum magnitude recorded, to date Today, it has been 4,2. In the past 24 hours, 176 earthquakes have been located with maximum magnitude of 3,4.
The following animation shows the evolution of seismicity located by the Canary Seismic Network under the island of La Palma since last September 12, 2021. In the animation, only earthquakes of magnitude equal to or greater than 2,0. Earthquakes of magnitude greater than 3,0 appear as blue rhombos while those of magnitude more than 3,0 appear in yellow rhombos.

There goes another water reservoir. The lava in this image is advancing north of the Montaña de Todoque. Lava will thus one day flow into the sea again, from the north side of this 2k year old cinder cone.

To put some of the measurements in perspective I just looked up an hectare. It is 10,000 square metres. That's roughly a Football pitch. I say roughly because there seems quite a variance in the size of pitches. Anyway, it helps me to visualise and appreciate some of the affected areas.

Been watching the live stream on my phone. Looks like another lava stream started up 10 minutes ago.




second pic a few minutes later - the flow is growing fast.

Enrique did an update yesterday.

10/10/2021 h Canary Islands.- PALM ISLAND ERUPTION.- TAILS ABOUT TO GET TO THE SEA, BUT HAVE ARRIVED NOW (PHOTO I THINK IS NOT FROM NOW). - After bordering the mountain of Todoque coming down alongside the North of ancient flow, the fast flow (9 A flow) and fluid has followed its path to the coast and will arrive tonight to the ocean to touch the sea water ( see pictures and map).

EDITED: Around 22.55 pm Canary Islands north flow arrives in the ocean.

https://twitter.com/i/status/1447319876142501891

The other 9 B flow keeps dropping further north yet and on an Antena 3 show I've seen it's very well fed so it won't stop and go over 500 m per hour with two fronts of 100 m wide each, it is divided into the polygon with which destruction will be greater, but will eventually end up bounding or climbing on top of the first 9 A flow when it reaches the north side of the mountain of Todoque ..

Regarding the volcano continues its special eruption very maintained and with continuous lava squares by its low mouths and burning pyroclasts climbing 400-500 m above the cone of the highest mouths, with more powerful moments where it overflows alternating with moments more stable, all of which continues to make Jet noise and explosions that form sonic waves that vibrate windows up to 10 km away.

These days the volcano morphology has changed and more pyroclasts have fallen on its south and west side, causing a larger volcanic building to be built and flow pour now mostly northward.

THE ENJOY.. this today has crumb, I tell you, after these more intense earthquakes there are changes, the first and most evident is that the magma moves upward, and this is revealed by three factors, it shows that there are several earthquakes in depths less than 7-8-9 km, you can tell because from today and something after 4.2 the other day episodes of spasmodic tremor with many earthquakes in a row that indicate that movement in depth and third, the appearance of much 18 Hz noise on spectrograms, in the form of a typical band depressurizing deep fluids around 10 km... white and bottle.

This will be confirmed in the coming days where deformation should be singing with increasing inflation or lifting the ground due to increased pressure. The volcano is also making a lot of noise due to gas depressurization in the 5 and 8 Hz line and the magma by frictioning with the conduit walls at frequencies between 0,5 and1 Hz... let's go spectrum tells me everything.

Now, I hope this new magma pulse reaches the surface through the current conduit that will overpress so that when it reaches the surface it is possible that some new mouths will open. But there is another option, and the pressure is very high and looking for an alternate route I do not think, but seismicity and deformation I think would indicate us at least 24-48 h ahead to the appearance of it.

I'm inclined to think that second possibility is less likely while the eruptive channel is open, but if this channel closes or shutters, I'd do as in 1949 heading out through the summit zone by the Nambroque or something else south towards Summit Old and even further south in the Degollada, but the current eruption has to stop for that to happen. In 1949 he did, after 18 days of the eruption stop. And that's it.

Sleep calmly today, it will keep moving and I don't think it will do anything new except some collapse or overflow of the lavic channel as we're watching on TV.

I finish with a term you may have heard and do not understand its meaning ′′ a Kipuka ": The kipuka is a Hawaiian tree with a beautiful red flower that reminds of a madroño from afar, but that does not look close and that grows on lava flow. Sometimes lava flow leaves an island or area unattended and the forest of kipukas survives leaving an island of vegetation, so that area is known as a kipuka, an area surrounded by devastation caused by lava coladas who have surrounded her and miraculously saved from flow(usually by being on a high, but not always). Another acceptance for these areas is a ′′ Dagala ".

Good night and until tomorrow... I will be answering the pile of messages and making a map, I'm not done, it's many and by many means. (Enrique)

PS: I recommend the following video of the 2018 Hawaii eruption and how the inhabitants attempt to redo their lives. (If you are sensitive, don't watch it, I know you are going through the same thing).

EDITED: NEW TEMBLOR OF 4.0

Well, a strong one, this one wasn't expecting it, as I say it's changing, don't forget to fill out the questionnaire, it's been noticed across the island. (Enrique)
