3,000 people are confined in El Paso and Los Llanos for the fire of a cement factory
The Weather forecast on the island "is bad" for the next three days

The direction of Pevolca (Canary Islands Volcanic Emergency Plan) has ordered this Monday the home confinement of almost 3,000 people in various areas of the municipalities of El Paso and Los Llanos de Aridane after the release of gases from the combustion of the plant fire of cement located in the industrial park of Callejón de la Gata.

This was announced at a press conference by the spokesman for the steering committee, Miguel Ángel Morcuende, who pointed out that the affected area covers approximately an area between the Tajuya crossing and the El Paso soccer field.

In addition, he has indicated that the Weather forecast on the island "is bad" for the next three days since the trade wind blows with little force and the sea breeze pushes the ashes to the east, which can affect the operation of the airport .

Morcuende has commented that this confinement is adopted as a precaution and to "avoid possible health problems", and will be reviewed throughout the afternoon once the air quality in the environment of the cement factory is analyzed.

However, he has commented that it is "reasonably good" given that except at some specific moment in the last morning the particles are below the thresholds that can present a risk to health.

The spokeswoman for the scientific committee, María José Blanco, has indicated that the volcanic plume of ash and gases reaches 4,000 meters in height and although it is "unlikely" that the ash reaches the north of Tenerife and affects the operation of the Tenerife airport North, it has warned that the east of La Palma is the most affected area and therefore, there may be problems at the airport.

With data from this Sunday, the emission of sulfur dioxide remains "at high levels", with an underestimated amount of 7,652 tons per day while the Cumbre Vieja ridge in total reaches 1,884 tons of carbon dioxide, in any case, without danger for tourists or visitors.

New laundry is approaching the sea faster
The area affected by the lava already exceeds 591 hectares, 65 more than yesterday, and the maximum width of the wash is around 1,520 meters

NOTICES DIARY11/10/2021 · UPDATED 18:27


The Steering Committee of the Special Plan for Civil Protection and Attention to Emergencies due to Volcanic Risk of the Canary Islands (PEVOLCA) of the Government of the Canary Islands, headed by the Minister of Public Administrations, Justice and Security, Julio Pérez, has analyzed the daily report of the Scientific Committee that points out that the initial flows weaken while the new one, located further north, approaches the sea more quickly . The advance of this north flow has caused the fire in the cement factory of the Callejón de la Gata industrial park and the consequent release of gases by combustion of materials, which were initially estimated as possibly toxic.

The cement factory fire has forced PEVOLCA to confine circumstantially several population centers of Los Llanos de Aridane and El Paso, a situation that will be lifted as soon as the air quality parameters improve in those areas, which is expected to happen soon. . Specifically, the confinement of about 3,500 people has been declared in the space between the crossing of Camino Cruz Chica with the LP-2 highway, continuing west to the crossing with Nicolás Brito Pais, continuing this road to the ring road and through it until the Hoyas Hondas roundabout. From this point on, the entire area affected by the August fire is included up to the El Paso soccer field, including the area from the west of the LP-3 to the Sombrero roundabout.


Among the recommendations of the authorities is to close the doors, windows, blinds and all air inlets from outside; If possible, confine yourself to the innermost rooms and interrupt any system that brings in air from outside. In case of being outside, it must be taken into account that a vehicle is not a safe place and it is necessary to seek refuge in the first building that is found. No travel should be made until instructed to do so, and only use the 1-1-2 phone for emergency situations. If due to force majeure any of the confined persons must interrupt the confinement, it must be communicated to 1-1-2.

The Technical Director of PEVOLCA, Miguel Ángel Morcuende, pointed out that there are three active streams, all of them through the exclusion zone evacuated since the beginning of the eruption. In addition to the original one, which ended in the sea and created the lava delta, there is another one further south that is on the strip of the San Juan eruption in 1949 that goes towards the Charcón, and the third one, further north, with two branches. One of them is burning the cement plant and the other is advancing in the direction of the sea, above the Todoque mountain, Morcuende explained, who explained that this northern stream has a greater supply of lava, which has increased damage to crops and buildings. and obliged to take this last measure of civil protection of confinement.

In this sense, the spokesperson of the Scientific Committee and director of the IGN in the Canary Islands, María José Blanco, explained that, after the overflow of the lava lake, the main flow runs along the north flank, mainly towards the sea, going down the northern part of the previous castings, following trajectories towards the west, within the exclusion zone. He indicated that the distance from the front of this lava flow to the sea is of the order of 300 meters, so it can form another lava delta (fajana) on the beach of El Perdido, in case the current emission rate is maintained. from the eruptive center.

Likewise, he pointed out that the lava field that fed the lava delta of the beaches of Los Guirres seems to have reduced its activity, as well as the wash that runs over the fajana of the 1949 eruption in the El Charcón area.

Morcuende explained that the area affected by the lava already exceeds 591 hectares, which is 65.33 more than yesterday, with a maximum width of the wash of 1,520 meters.

In addition, he pointed out that the updated data from the cadastre on Copernicus puts the affected buildings at 753. Of these, 620 are for residential use, 70 for agricultural use, 29 for industrial use, 19 for leisure / hospitality and 7 for public use, among others.

As for the area of ​​crops, he said, it is estimated at 150 hectares affected. Of these, half are banana trees, 45 hectares are vineyards and almost 9 are avocados.

Regarding seismicity, since yesterday there has been a high number of earthquakes located slightly south of the area where the swarms that gave rise to the eruption began. "The most relevant thing is that they are at medium and high depth," he explained.

With regard to air quality, he added that except for the measure adopted at the last minute of confinement of a very localized area due to the fire that affected the cement factory, the values ​​recorded since yesterday indicate that the quality it is reasonably good, except for a very specific peak. On the suspended particles, he explained, they are below the permissible threshold.

However, Morcuende indicated that the thermal inversion layer is currently at lower levels than in recent days, which will not help the dispersion of gases.

The wind configuration disposes the ash plume and SO2 in a west-east direction from the eruptive focus. According to Blanco, the expected position of the plume will affect the operation of the La Palma Airport and he spoke that the area most affected by the ash fall is the eastern slope of the island. Although it is unlikely, the fine ash fall could reach the north of Tenerife and affect airport operations on the island, he said.

DAILY OPINION OF THE SCIENTIFIC COMMITTEE
Before the meeting of the PEVOLCA Steering Committee, the Scientific Committee of the Plan met in which its members presented their conclusions on the evolution of the eruptive phenomenon since yesterday. This Scientific Committee is coordinated by the General Directorate of Security and Emergencies of the Government of the Canary Islands and is made up of representatives of the National Geographic Institute (IGN), Higher Council for Scientific Research (CSIC), the Canary Islands Volcanological Institute (Involcan), the Geological and Mining Institute of Spain (IGME), State Meteorological Agency (AEMET), Spanish Institute of Oceanography (IEO), University of La Laguna and University of Las Palmas de Gran Canaria.

Such conclusions were:

“The fissure eruption continues to show a strombolian mechanism (that is, a mechanism of a mixed nature, with explosive phases that produce pyroclastic deposits and effusive phases that simultaneously produce lava flows). In volcanology, the magnitude of volcanic eruptions is measured on the scale of the Volcanic Explosivity Index (VEI) with values ​​between 0 and 8; in the case of this eruption, the VEI estimated so far is 2.

Since yesterday's overflow of the lava lake, the main flow runs along the north flank, mainly towards the sea, down the northern part of the previous flows, following trajectories towards the west, within the exclusion zone. The distance from the front of this lava flow to the sea is of the order of 300 m, so it can form another lava delta (fajana) on the beach of El Perdido, in case the current emission rate is maintained from the eruptive center. Large blocks carried by lava flow further north are still observed, although less frequently. The emission centers of the crater are still active and the appearance of new emission centers in the surroundings of the main cone, as well as other surface observables (visible gas emissions) within the exclusion zone, is not ruled out. The lava field that fed the lava delta of the beaches of Los Guirres seems to have reduced its activity. The lava flow that runs over the lava delta of 1949 in the El Charcón area, also seems to have reduced its activity.

During the eruptive process, the estimated emitted volume (up to 10/10) through the SEVIRI sensor of the HOTSAT system is 75 ± 25 Mm3

The morphology of the cone changes repeatedly due to the successive processes of growth and reconfiguration. The eruptive process can show episodes of increased and decreased strombolian activity, as well as pulses with phreatomagmatic activity.

The height of the ash and gas column measured today, as well as its dispersion, reaches 4000 m.

As the lava delta has reached the limit of the insular platform, if the advance continued to greater depths, partial collapses of its front could occur, which could be accompanied by sudden release of gases, hydromagmatic explosions and generation of waves, in the environment of the lava delta and always within the already established exclusion zone. The marine plume is severely weakened along the edge of the lava delta.

The weak wind continues at low levels, with a predominance of the breeze regime on the west slope of La Palma. The thermal inversion will remain located around 1000-1200 m and is more pronounced (approximately 3 ° C) in the early hours. These meteorological conditions have an unfavorable local effect in the areas of El Paso and Los Llanos with respect to air quality, since together with the surrounding orography, the dispersion of pollutants is prevented during the early hours and early hours of the morning. At altitude (between 1500 to 5500 m), the wind will continue from the west component and no changes are expected in the next 72 hours (at least). This wind configuration disposes the ash plume and SO2 in a west-east direction from the eruptive focus. The expected position of the plume will affect the operation of the La Palma airport and the area most affected by the ash fall is the eastern slope of the island. The fall of fine ash in the north of Tenerife and the effect on airport operations on the island is unlikely.

Seismicity continues to be located, mainly, close to the seismicity of the first days, at depths between 10 and 15 km. There are also earthquakes located at depths greater than 20 km with an increase in their number. In the last 24 hours the number of earthquakes has increased. The maximum magnitude observed was 4.3 mbLg, the maximum intensity was III-IV EMS. The current level of seismicity continues to indicate that more felt earthquakes are possible, which could cause small landslides in sloping areas. The deformations at the stations closest to the eruptive center do not show any significant pattern.

During yesterday (10/10), the emission of sulfur dioxide (SO2) associated with the volcanic plume (visible emanations) continues to register high values ​​in line with the eruptive process, reaching values ​​of 7652 tons per day (underestimated value). Likewise, the diffuse emission of carbon dioxide (CO2), associated with the 220 km2 of the Cumbre Vieja volcanic ridge (not visible emanations), has been estimated at 1884 tons per day as of 10/10. These invisible carbon dioxide (CO2) fumes do not pose any danger to residents and visitors. The diffuse CO2 emission at the Los Llanos geochemical station (LP10) reflects a higher magmatic-hydrothermal fraction than that observed at the Fuencaliente geochemical station (LP08). All these geochemical observations are consistent with the current eruptive process.

Regarding air quality, yesterday there was a peak of sulfur dioxide (SO2) during the morning at the El Paso and Los Llanos stations with maximum values ​​close to the hourly threshold (established at 350 µg / m³) but without reaching exceeding it, throughout the day the values ​​remained far from the threshold. During this morning there has been a peak of great intensity at the El Paso station with an hourly maximum at 8:00 am of 830 µg / m³ that exceeds the alert threshold (established at 500 µg / m³) but at a only occasion. At the moment the values ​​are decreasing and below the hourly threshold.

Regarding particles smaller than 10 microns (PM10), yesterday and today we continue with values ​​below the daily threshold (set at 50 µg / m³), ​​so there has not been any exceedance of said threshold at neither station.

OBLIGATIONS AND RECOMMENDATIONS
MARINE PENACHO:

It is suggested to pay close attention to the wind forecast to monitor the possible changes in the direction of the plume and act accordingly, especially those with a weakened respiratory system (for example, asthmatics) as they are more vulnerable to lower concentrations.
Eye flushing is also recommended after any exposure, as symptoms are often not noticed until later.
These marine plumes can be seen up to several kilometers from the source, although more diluted. In the event that the marine plume reaches population centers, it is recommended to stay indoors whenever possible and close all doors and windows.
For the safety of the navigation of scientific vessels that carry out scientific work in this area, it is recommended to maintain a distance of at least 500 m. Navigation for scientific purposes for emergency management can be carried out at shorter distances, under the responsibility of the owner and the captain or skipper of the boat, as long as it has the approval of the Technical Directorate of PEVOLCA and Captaincy. Maritime.
LAVIC WASHES:

It is also recommended not to approach the lava flows due to the risk of being exposed to the gases emitted, possible landslides and high temperatures.
Given the large thicknesses of lava flow observed in some points, collapses of its face can occur which, in steeper areas, can lead to the formation of large fragments of lava flow, which can detach from the face of the wash and that sudden reaching distances of several meters from the pouring face, depending on the topography. Also in steep areas, small pyroclastic flows can occur.
FALL OF PYROCLASTS:

It is recalled that an exclusion radius of 2.5 km is established around the emission centers to minimize the risk of impact from pyroclasts and exposure to gases.
In case of intensification of the explosive activity it is possible that some violent detonations could cause breakage of the glass of the windows. It is recommended to stay away from the windows up to a radius of 5 km from the cone.
In areas affected by intense ash fall (a clear deposition on the ground is observed) and even more so if mist is observed, it is recommended to stay indoors. Outdoors, the use of FFP2 masks and eye protection systems is also recommended.
Before the arrival of ashes to other islands, it is recommended in those affected, the use of surgical masks. It is recommended to clean roofs where ash thicknesses of several centimeters accumulate. It is insisted that the procedure for removing ash from roofs and soil indicated by Civil Protection be followed precisely (moisten ash, eye protection, wear a mask, protect the skin, ..., see attached documentation). For removal, use FFP2 masks, gloves, dampen slightly for sweeping and do not use blowers under any circumstances. The use of blowers increases the resuspension of the most harmful particles to health.
For the safety of scientists on the ground within the exclusion zone, it is recommended to maintain a distance of at least 1000 m from the main emission center. The approach at shorter distances can be carried out, for scientific observation purposes for emergency management, with the approval of the PEVOLCA Technical Directorate.

Respect for the land and maritime exclusion zones remains imperative in order to maintain the physical integrity of people.

Continuous monitoring of activity has been strengthened and any significant changes observed will be reported. Stay tuned to the information provided by the corresponding Civil Protection authorities ”.

La Palma volcano enters "effusive phase"
Insatiable, this new lava flow advances on its destructive path. It reaches the town of Todoque and devours some houses that still resisted. Homes that fall apart amid the flames and within reach of a faster-flowing wash. At three hundred meters per hour, in its most fluid zone, five minutes are enough for that green house. It floods the road and buries abandoned cars. It threatensly approaches other buildings such as the school and reaches this area of ​​greenhouses burning plastics and fertilizers that cause this toxic cloud. The base of the wash is, every time, wider and its height imposes even seeing it from afar. Lava is now emerging from a smaller crater, but with the same devastating effect. The volcano emits more than 560 tons of sulfur dioxide daily, although it does not affect, at the moment, the quality of the air. The ashes that it expels exceed five thousand meters in height and in the next few hours could reach the islands of La Gomera and Tenerife carried by the wind. Meanwhile, on La Palma, the Cumbre Vieja will continue to leave an incandescent path.

I would have thought that in the space of 3 weeks, the fertilisers from the agri plantations and the chemicals from the cement works, could have been removed to another part of the island for safety!

Herrman Guerrero
Muchísimas gracias Enrique.
Hoy mismo me causó esto muchísimo cuando el canal de youtube de Ayto el Paso sube un vídeo de dron del 9 de octubre tan panchos....tremenda vergüenza.
Si no es por Antonio Carrillo, Mike y tú los políticos y los medios nos tienen en penduras en lo que a coladas, pendientes y topografía respecta mientras nos muestran el conito 24/7 en vivos de youtube y nos hablan de lo que ya sabemos una y otra vez...tremenda indignación. No es solo la falta de información que jode sino que encima también es muchísima des-información.
Gracias hasta el infinito de verdad.

Herrman Guerrero
Thank you so much Enrique.
Today this caused me so much when Ayto El Paso's youtube channel uploads a drone video from October 9 so panchos.... tremendous shame.
If not for Antonio Carrillo, Mike and you, the politicians and the media have us in penduras in what to flow, earrings and topography concerns while showing us the cussy 24/7 live on YouTube and tell us about what we already know and again... tremendous outrage. It's not only the lack of information that screws but it's also a lot of de-information.
Thank you to infinity for real.


Maria Morales
Enrique Gracias, a ti a Mikel,por lo menos muchos palmeros @ te leen y siguen tus consejos, esta noche están vaciando el supermercado Spar que está en la línea de la colada, Si al menos los vecinos de la zona tuvieran ese aviso de lo que podía suceder en esa zona quizás hubieran recogido más cosas de sus hogares, con tiempo y no ahora tan solo 15 minutos..que se te van en despedirte de lo que fue tu hogar..que tristeza , por muchos ánimos, que demos, son ellos los que están sufriendo esta catástrofe, sin saber donde comenzar y cómo de nuevo

Maria Morales
Enrique thanks, to you to Mikel, at least many palm islanders @ you read and follow your advice, tonight they are emptying the Spar supermarket that is on the line of laundry, If at least the neighbors in the area had that notice of what that could happen in that area maybe they would have collected more things from their homes, with time and not now just 15 minutes.. that you are going to say goodbye to what was your home.. that sadness, for many encouragement , let's give, they are the ones who are suffering this catastrophe, without knowing where to start and how to again

Mike Hollister espero que de esta desgracia, el Gobierno de Canarias comprenda que los niños de esta tierra y los adultos de hoy, tenemos que tener conocimiento de donde vivimos. Por esta desgracia yo misma he sido consciente que vivo sobre volcanes. Nunca pensé verlo. Y felicidades por esta página, espero que su esfuerzo sea recompensado. Me encantaría que dieran clases y cursos. Espero que cuando esto pase, o cuando se pueda puedan organizar un proyecto didáctico.

Mike Hollister I hope that from this misfortune, the Canary Islands Government understands that the children of this earth and the adults of today, we have to know where we live. For this misfortune I myself have been aware that I live on volcanoes. Never thought I'd see it. And congratulations on this page, I hope your effort is rewarded. I would love for them to give classes and courses. Hopefully when this happens, or when you can organize a didactic project.

Tamara if Enrique can plot and warn the islanders where the next lava flows will happen why on earth is Pevolca not doing the same thing thank goodness  some of the Islanders are following Enrique and heeding what he says.

Its ridiculous as one of the posts I added in the above comments say  that they had only 15 minutes warning before they had to evacuate .

I personally think its stupid for the Cabildo to tell tourists to come to the island its safe .

I cringe when I see the live feeds where people are still driving on roads next to a lava flow and stood watching close by. It will only take a surprise full collapse of the cone for all the magma to roll down the hill in seconds and engulf them all.

This eruption is so unpredictable its not stopped erupting since 19th September the earthquakes are getting stronger and there has been a M4.1 this morning with a IV intensity.
