26/11/2021 20:00h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 69. - LOW PRESSURE ON INFERIOR RESERVATION BUT CLIMBS ON THE TOP AND IN THE EXIT DRIVER. - NEW MOUTH & NECKLACE 18. - VISION OF IGME PALMA. The volcano continues and although in general lines it seems that something low, I do not see it very convinced to stop, in fact I think it will take more activity, in view of the increase in pressure in the main conduct because you can see an inflation in LP03 and not Alone Today's data where it goes up 2 cm, but it's been several days, meaning that the contribution of lava is obvious....

This increase in pressure is reflected in the opening of new mouths like yesterday, which would not be rare that it had reactivation, it came out under a house no less, if this happens on the day of the eruption the house would have flown in the air.... there was a lot of luck.

SEISMICITY AND DEFORMATION

Nevertheless, vibrations are noticed in the valley, follow the emission of coladas and ashes, with moments or pulse of more activity and emphasize that the seismicity is seen much more deeper than other days not only in the data, but in the spectrum, after the tea 4.8 of remote last night there was a swamp yesterday between 23 and 24h around midnight which has been different from everything we've had, the signal is different, more than 100 earthquakes on the spectrum and not very well that it is, because it's almost a spasmodic tremor but very shallow. IGN has located only 4 of them.

Then the system has stopped and followed by a couple of freatomagmatic explosions at 02:20h, a noise is seen in all frequencies after which the system stops and calms in seismicity for hours. Now it's getting power again and earthquakes occur again in both the upper reservoir (10-12km) and the lower (34-37km).

Yesterday we had an Earthquake in the deep area, and yet it was not followed by a deep swarm that looks good in the Gomera, but by a swarm on the surface camera. If to this we add that in MAZO, LP06 and LP05 go down (LP05 much for my taste, it seems like an incorrect fact, let's see what they put tomorrow) it indicates a loss of pressure on the deepest levels and would explain that tranquility of the deep sismicity du Rante the day, until now a few hours past noon that it has restarted.

HORROR:
The tremor is maintained, but the lava is more fluid, less viscose and less rosy, let's say, which makes less noise, but its flow and speed has increased by lowering the viscosity and increasing the speed has not produced an increase in the tremor, but from the 22nd day it's very stable in 18-17 units of RSAM slowly declining with some activity peaks highlighting what has occurred past noon.

NECKLACE MAP:

Follow the contribution to the lava tubes and lava canals that go through the west of the cone and over the current field of coladas, where they already accumulate thickness of up to 50 meters of coladas thickness, is the flow 17 and that in the front has two branches les, one to the north going to the area where there was Todoke and another more to the south, which has passed through the southeast of Mount Todoke and which was turning south towards the south edge, heading towards the Norias area, (if it has not gone out where the flow would follow this south edge towards the Ocean, in case it goes out, because it could be a solution for one of the canals or lava tubes that were going around the 15 laundry.

The 18 flow that came out yesterday under a house, has not done it in the original pond, but more to the southwest, in the pond that passes under Mount Rajada, which indicates that the system of presurizing has inflated the entire area of the cone and lava has searched another way of less pressure or effort, forming a fountain of lava when broken. It's very rare that these earthquakes of superficial breakage have not been detected by the IGN, it's very strange that they are not detected, because if they happen, they occur. Luckily after a few hours, it has stopped, but if it pressures again, as it seems, it will come out again for that point or another close one.

GASES, ASHENSES AND GEOCHEMICS: With the rain, the gases are dragged and breathed better, in fact, what a falling drizzle, with lightning and storms that rewind with the heat of the coladas that release steam and make it still rain more and what is left for falling. The next few hours will rain a lot. At first the ashes are getting hardened, being angulish grains and emitted by a low energy eruptive center, at first the only fear is the weight they give to the wet and will be partially cemented, so they will remain hard pairs to form a toba, so Typical island like the toba used in canaries for construction. At the moment I don't think there will be lashes or slips, as that happens if the ash meets the rain in the air or this is very thin for a total shredding in microscopic particles, which is not the case.

NEW IGME MAPS, IT'S ABOUT TIME SOMEONE DID SOMETHING GOOD FOR EVERYONE.... Some updated maps, some updated photos, official numbering of the PEVOLCA, - the 18 that I put yesterday is the 11th of the Pevolca, by the way - know what happens, that it is not only in this space, but at the level of the entire citizenship... fell for the IGME.!!

SEISMIC ENERGY>:

It's going down, but it's a lot of inertia, that 4.8 has released almost all this early morning, about 50MWh yesterday.. 300MWh today, but if this Earthquake is removed, it's much less. , about 50MWh like yesterday. But don't trust him, he's still very alive, I don't see the end for the moment, we'll see what he has prepared us for the next days, because weeks if we have left, and it's going to be a surprise Much encouragement to all Palmeros.

The chilling image of the new eruptive mouth on La Palma that has emerged just below a house
The reopening of an eruptive focus in the main cone this Thursday has led to the advance of a wash over the Las Manchas cemetery and the field of solar panels, also destroying many buildings
- The destroyed cemetery housed the remains of more than 3,000 deceased and the only crematorium on La Palma

The volcano of La Palma once again leaves a new chilling image to remember: the last eruptive mouth opened this Thursday just below a house in Corazoncillo, in Las Manchas. This has been confirmed by images taken by a drone for the El Paso City Council and later shared on social networks.

The house, which is covered with volcanic ash, is hit shortly after by a wash, being totally destroyed. Fortunately, this event occurred in an exclusion zone, south of the main cone of the volcano, so the damage is only material.

The reopening yesterday afternoon of an eruptive focus on the eastern flank of the main cone of the La Palma volcano has led to the advance of wash 10 on the Las Manchas cemetery and the field of solar panels, also destroying many buildings, especially single-family homes, and finally joining the laundry number 11.

The technical director of Pevolca, Miguel Ángel Morcuende, reported at a press conference that the rest of the lava advances on previous flows, forking into two areas: one towards flows 4, 5 and 7, located between the mountains of Todoque and La Laguna. , and the other towards wash 9, which could overflow towards the south and affect other locations, although at the moment it is "quite stopped".

Regarding seismicity, the technical director indicated that it is located in the same areas, deep seismicity continues to register low values ​​and there is a marked decrease in the medium term of the intermediate. Likewise, the amplitude of the tremor remains at low values, although with spikes in high values.

The emission of sulfur dioxide (SO2) continues to register high values ​​but the downward trend has been maintained since last September 23, when the maximum levels were registered. In addition, the deformations are "absolutely stabilized" in all stations and tomorrow, Saturday, a favorable scenario is expected for aeronautical operations.

Regarding the number of shelters, there are 513 people in hotel centers. Of the total, 412 are staying at the Fuencaliente hotel, 31 in Breña Baja and 70 in Los Llanos de Aridane. In addition, there are 43 dependent people cared for in insular health centers.

I measured the distance of the new flow 18, the focus is 1km from the SE crater or 900m from the main no less. on another parallel dam, surely, the one that formed the cone of Rajada Mountain. To say the flow went over 1500m in a few hours.... a whole warning. (Enrique)

Lava flow number seven widens towards the mountain of La Laguna
On day 69 since the eruption began in the Cabeza de Vaca area, there is still a contribution of lava, mainly in the central areas of the fronts of flows 7, 4, 5, 1 and the widening of stream number 7 towards the La Laguna mountain threatens to close access to the observation point set up in that area, which is also where most of the drones used to monitor the advance of lava from the volcano in Cumbre Vieja take off.

On the other hand, wash number 10, the one located further south, which crossed the Las Manchas cemetery, has joined line 11 and, in principle, it does not seem that it will cause more damage, the spokesperson of the steering committee has indicated of the Volcanic Emergency Plan of the Canary Islands (Pevolca), Miguel Ángel Morcuende.


On day 69 since the eruption began in the Cabeza de Vaca area, there is still a supply of lava, mainly in the central areas of the fronts of flows 7, 4, 5, 1 and 9, both on the surface and through tubes. volcanic, in this case on the fronts.

The spokeswoman for the scientific committee, María José Blanco, has indicated in any case that the lava flows through areas already trodden, although in the last hours "small overflows" have been detected in the Las Norias area, although the movement of the molten rock it is very slow".

Blanco has also said that two small eruptive fissures located yesterday to the south of the main cone are already inactive.

The total area affected, both on land and in the fajanas area, is 1,151 hectares.

María José Blanco has indicated that yesterday, Friday, it was not possible to make a measurement of sulfur dioxide in the plume due to the rain, although it "most likely" continues at high values, between 1,000 and 29,000 tons per day. Neither could the diffuse CO2 emission in the Cumbre Vieja building be measured.

Regarding the elevation in 6 centimeters from the ground in the station closest to the cone, he has indicated that it is a local episode, and has pointed to the possibility that the meteorological conditions could disturb the data.

He has emphasized that the intermediate and deep seismicity remain at low levels, although the possibility of earthquakes of intensity V and VI that can cause small landslides in sloping areas remains, and the tremor signal also remains at low levels.

The best news is the direction of the ash and smoke cloud forecast for the next 48-72 hours, towards the east and southeast, which will favor the operation of the La Palma airport, as well as the low probability of precipitation there. time interval, in any case weak and on the east side of the island.

Likewise, air quality has improved and in all seasons the values ​​of SO2 and particles below ten microns are between good and reasonably good.

However, the increase in trade winds in the El Paso area has caused a recirculation of the ashes already deposited and the air quality has worsened in the south of the Aridane valley, within the exclusion zone, which prevents access of neighbors and irrigators during the day today.

The updated number of people housed in hotels is 526, 13 more than yesterday, in addition to another 43 dependents, housed in social health centers on the island.

According to data from the Cadastre, there are 1,506 buildings affected and 341.51 hectares of agricultural land destroyed: 212 of banana trees, 60 of vineyards and 26.42 avocado farms.
