The emergency situation created by the Volcano de la Palma will be sharpened in the coming days for the rains.
With some forecasts of up to 15 liters per square meter and time for Friday, the Emergency Plan experts have warned the population on Wednesday about the risk of riapers and collapses on unstable slopes.
They can cause, have said, “traffic and life problems of people”.
A scenario even worse in the area of the palm closest to the eruption would be the formation of larks or clay casting by mixing the water with the pyroclastic materials deposited on the surface.
More than 90 hectares of surface of La Palma not covered by lava will be lost because they are isolated from cast, as explained by Wednesday Miguel Ángel Morcuende.
It is, according to him he has said, fundamentally of plataneras.
“The energy of the system is moving towards the castings located north,” has described by reviewing the map the Technical Director of the Emergencies Plan, which has also spoken of “small contributions” in Las Coladas 1, 2 and 9.
On those castings north, Morcuende has detailed that La Colado 4 has joined 7 and the flow moves through the latter towards the sea.
“In principle, we do not believe that progress number 4, but it can happen if the 7 finds an obstacle in its progress.”
At the top of the map that he has shown, the red line marked the power line to that wash 7 and the area where a few days ago contacted the Atlantic.
Seismicity at intermediate depths follows “at low levels” and continues to be located in the same areas of La Palma, according to the summary provided by the Emergency Plan.
In depths above 20 km, seismicity continues on “an intense level with a slight decrease” with respect to the previous day.
The Emergency Plan has updated the number of people evicted by the Volcano de la Palma that follow, two months after eruption, in public establishments.
The number of people housed in hotels, a total of 505, although there are three new revenues in Fuencaliente (436) and three outputs (69) in the Plains of Aridane.
The number of dependent people housed in island sociosanitary centers remains at 43.
Another risk associated with the next rains in La Palma are the casting of clay or Lahare.
They originate on the slopes of a volcano by mixing pyroclastic materials with water from rainfall.
From there they move, attracted by the force of gravity, towards the areas located in lower dimensions.
This type of mud castings usually occurs when there is a lot of accumulation of newly expelled pyroclastic materials in a mountainous area with pronounced earrings, and when there are very violent storms or sudden melting of glaciers.
On the slopes of the volcanoes, this type of flow can reach very high speeds and destroy any obstacle on its journey.
A “terrible example” of Lahar is the 1985 in Colombia, caused by the sudden melting of a glacier in the Ruiz’s Nevado eruption, as Lorenzo Pasqualini, Meteored Geologist.
The new Lavic delta that is being formed for two days in the north of the magma castings that emanate from the Palma Volcano has extended in 5 hectares on the sea the surface of the island and reaches up to 350 meters away from the line
Coast.
To this new insular area is added that of the other Water Delta formed south of the castings, which occupies 43.46 hectares over the ocean, according to the data provided by the spokesperson of the Technical Committee of the Volcanic Emergencies Plan (pevolca),
Miguel Ángel Morcuende.
Miguel Ángel Morcuende, Technical Director of the Emergency Plan, has warned this Wednesday that the guidance of the plume generated by the Volcano de la Palma will cause problems – due to the ash – in localities such as Santa Cruz de la Palma, Breña Alta and
Breña Low, located in the west area of Dela Palma.
In these municipalities, the use of FFP2 outdoor masks is advised.
“We do not recommend physical exercise outdoors in the next 24 hours,” Morcuende remarked.
In its comparison, the emergency plan spokespersons have also ratified that they will continue the problems of operability at the airport of La Palma, where due to the ash they do not land or take flights from last Saturday.
“The plume is going to have an east or northeastern layout that, among other things, the airport activity will hinder, we will have problems of operability,” Miguel Angel Morcuende said.
Precisely to the forecasts of intense rain on the palm, this noon was referred by the technical director of the volcanic emergencies, Miguel Ángel Morcuende.
The forecast talks about 60 liters per square meter in twelve hours and up to 15 liters in an hour that is expected “on Thursday, on the east of the island and on Friday will be generalized to the whole island.”
For this reason, he has advanced “a notice to the population for next Friday” on what he has called “hydrological phenomena”.
Specifically, he has asked that “avoid exposure in vagues in which a certain flow can generate problems.”
He has detailed after he was referring to “problems of traffic and life of people.”
“What we can have is some important hydrological flow,” he added, specifying that the warning is concrete in “avoiding the places where water is evacuated” because “the problem is to be in the middle of a channel”.
MorCuende has cited a second risk situation.
According to him he has said, it is also necessary to “avoid landslides on unstable slopes”.
Two notices in which Carmen López, from the National Geographic Institute, has coincided.
“Do not transit in zones of caucas or be at the foot of strong pending,” she has summarized her.
Both have ruled out that rainwater, falling on lava and ash, can generate harmful health gases.
The meteored meteorologist, José Miguel Viñas, has warned this Wednesday of the creation of Lahares or cast of clay in the west of La Palma for the intense rains that are expected for this Thursday and Friday on the island and that join the
Accumulation of ash from the volcano.
This episode of rain will remain until Saturday and will be accompanied by West Winds in high areas.
One of the problems caused by the ash, pyroclastic material whose dimension is less than 2 millimeters, is its accumulation, points in a note Lorenzo Pasqualini, Meteored Geologist.
When stunning, for example, on the roofs of the buildings, their weight can cause landslides, and therefore it is important to remove it to avoid sinking.
This Wednesday has been met on the number 67 of the eruption of the old summit volcano.
Radio Television Canaria points out that in this way the duration of the Fuencaliente volcano of 1,677 – 1,678 has been exceeded, whose activity lasted for 66 days.
It was longer, according to the Canary Islands Volcanoes, the eruption of the Martín volcano or Tigalate.
It began on October 2, 1,646 and ended December 18 or 21.
Therefore, its duration was around 80 days.
This volcano was located at the southern end of old summit, about 2 kilometers from the mountain of El Kid.
According to the same source, the eruption was preceded by large earthquakes that made the inhabitants of their homes flee.
The natural phenomenon that is Elvolcán de la Palman stops producing images that we usually do not have access.
The last ones so far has shared by the Canary Islands Volcanological Institute.
This organism has taught 3D images of scanning electron microscope (SEM) ash particles 10 times finery than a hair.
They correspond, as explained, to the eruption of September 19.
The airport staff of La Palma continues with the cleaning tasks of the accumulated volcanic ash.
The priority is security.
We work in order to recover operation.
The airport of La Palma continues this Wednesday inoperative, for fifth consecutive day, due to the accumulation of ash, as reported that he noted that he is working to recover the operation as soon as possible, as long as the meteorological conditions allow him ”
.
In relation to this, Binter has reported in a statement that has been forced to prolong the temporary paralysis of the flights that connect with the island of La Palma throughout the day of this Wednesday.
Anyway, it qualifies that the paralysis of the operation will be maintained until the conditions improve and allow flying by guaranteeing safety.
He adds that he will inform of any news or change that could be given through his usual channels, while recommending that before flying he is consulted in the official media of the airline, the updated situation of the flight.
The Cabildo de la Palma has approved in an extraordinary full invert 7.1 million euros more to give an “agile and effective” response to the situation generated by volcanic eruption, and that will be allocated to infrastructures and social emergency aid.
The Insular Corporation has reported in a note that three credit modifications and the first, of 1.4 million euros have been approved, for the most part (1.2 million), emergency expenses and infrastructures
, such as road conditioning and road cleaning.
The remaining 200,000 euros will be allocated to maintain the UNED Set in Los Plains of Aridane.
Likewise, the second modification file is related to the area of social action and 250,000 euros will be provided, of which the plains of Aridane will be allocated 150,000 euros;
Step 60,000 euros;
Tazacorte 30,000 euros and fuence, 10,000 euros.
Seismicity at intermediate depths associated with the eruption of the Volcano de la Palma is significantly reducing in recent days, however, at great depth, more than 20 kilometers, it is intensifying since the beginning of November, the seismologist of the
National Geographic Institute, Itahiza Domínguez.
This Monday, the greatest number of seismic events located in a single day at a great depth was counted.
Specifically, 85 earthquakes around 30 kilometers, “more than double the previous maximum value in deep seismicism that was recorded on November 10,” said Domínguez
The Binter airline has decided to extend the suspension of operations with the palm until 3:00 p.m. on Wednesday at the persistence of the ash from volcanic eruption at the island airport.
The ash cloud maintains inoperative airport runway, reports Binter, which for fifth consecutive day suspends its flights with La Palma.
In principle, the first flight provided for this Wednesday remains from 3:00 p.m.
The airport of La Palma continues inoperative, for the fifth consecutive day, due to the accumulation of ash, as reported by Aena that he notes that he is working to recover the operation as soon as possible, “as long as the meteorological conditions permit”.
In relation to this, Binter has reported in a statement that has been forced to prolong the temporary paralysis of the flights that connect with the island of La Palma until 13.00, in such a way that the first flight provided for this Wednesday to the
15.00 hours, in principle, stays.
Anyway, it qualifies that the paralysis of the operation will be maintained until the conditions improve and allow flying by guaranteeing safety.
The National Geographic Institute (IGN) has located during the early morning of this Wednesday in Palma, 27 seismic movements, whose magnitudes have oscillated between 2 and 3.8.
The one of minor magnitude occurred at 06.43 hours in Fuencaliente 12 kilometers deep, while the 3.8 was located at 4.44 hours in Mazo and 11 kilometers deep.
Of the 27 earthquakes located during the first hours of this Wednesday, 15 have occurred in Mazo, 11 in Fuencaliente and 1 in El Paso.
“It is a conjunction of multipathurers. The intense rains by themselves are a problem and the volcano, too,” explained the volcanologist of the National Geographic Institute, Alicia Firpeto, to Canarias7.
“Even if it fell little rain, you have to be very careful with driving. The pavement with ash and rain is tremendously slippery. You have to circulate with common sense and caution,” added Firepo.
As of Thursday, the entry of a frontal structure is expected and subsequently of an Atlantic vague that will produce rainfall that may be of a strong nature, which will leave up to 60 liters per square meter in 12 hours, mainly in the east area of the island, situation
that will reverse from Saturday.
The State Meteorology Agency (AEMET) has already activated the Yellow Notice (Risk) based on this forecast.
In addition, it is expected that the ash cloud and sulfur dioxide (S02) is still arranged towards the E-NE from the eruptive focus, probably assuming an unfavorable scenario for aeronautical operation, mainly for the airport of La Palma, if the effusive activity
The volcano continues similarly.
The Deputy of Coalition Canaria, Ana Oramas, has advanced his vote in Congress against the draft general budgets of the State, among other reasons for not contemplating aid for the Island of La Palma, although he said after “Does not shoot the towel
“To try to include them in the accounts.
This has said it during its intervention before the full house of the Free House, which this week celebrates its latest debates before approved budgets and send them to the Senate.
Oraramas has asked for the inclusion of these aids, whether yours or other training, to give “certainty” to the inhabitants affected by volcanic eruption, beyond the aid contemplated in the last law decree approved by the Government.
As for the evolution of the castings, the technical director of the pevolca, Miguel Ángel Morcuende, reported that most of the energy continues to ride through the pouring area number 7 until reaching the new Lavico Delta.
This has made the affected surface already placed at 1,073 hectares.
The lavic delta located further reaches 43.46 hectares, 0.5 more than the previous data, reflecting that there is still a lava feeding, although very small, in the southern part of the emergency.
In addition, the maximum width between castings has increased to 3,300 meters.
The affected culture surface is figured by 326.6 hectares, 12.53 more, of which 198.26 are platnera, 59.93 are vineyards and almost 26 are avocateros.
As regards the number of households, there are 505 people in hotel centers, two more than yesterday.
Of the total, 433 stay at the Fuencaliente hotel and 72 in the Plains of Aridane.
In addition, there are 43 dependent people attended in island sociosanitary centers.
The Council of Ministers, at the proposal of the Ministry for the Ecological Transition and the Demographic Challenge, has taken reason for the emergency declaration of the actions for the supply of water for irrigation and other uses to the area affected by the eruption of the volcano in the
Island of La Palma for a maximum amount of 4 million euros and an estimated duration of two months.
The actions, which have already begun to ensure the availability of short-term water resources in the unleasted areas of the rowing, Puerto Naos and the bulb and are executed in a coordinated manner with the rest of the current administrations in the area, are the
following: Contribution of new sources of water, by installing mobile desalination machines at the Port of Tazacorte (Government of the Canary Islands; Transportation of desalted water and other sources between the Port of Tazacorte and the Port of Puerto Naos (Ministry for the Ecological Transition
); water drive between the Coast of Puerto Naos and the four-way raft (Cabildo de la Palma).
To the magnitude of volcanic eruption is joined by the scope of the damage that are being produced, as is the case of leaving without water supply for irrigation to some 600 hectares of platarents, which represent 25% of the platform production of
The island and employment for about 15,000 people.
The Molten Roca River that feeds the new lava delta off the coast of Tazacorte, in La Palma, goes down at a speed of 10 meters per second while next to the mountain of La Laguna, its last major obstacle before rushing slope
Below towards the cliffs, Informa Involcán.
The Canary Islands Volcanological Institute has published on your Twitter account a recorded video from the mountain of the lagoon in which it is appreciated how the laundry flows light at the feet of that elevation.
The speed attributed to you by your scientists (10 meters / second) is among the highest of how many have been registered so far on the casting at that distance from the cone, where the advance used to be measured in tens of meters per hour, sometimes
less.
Ten meters per second equals 36 kilometers per hour.
That means that casting like this can cover the distance between the cone of the volcano and the cliffs of Tazacorte (6.5 kilometers) in about ten minutes, in the event that the lava maintained that speed constantly throughout its journey
.
