Lava spreads through the northern flank of the Palma Volcano while the lagoon lag goes towards the sea by the Lost Viewpoint. The casts that are located south of the mountain of La Laguna continue to evolve towards the west of the island of La Palma with a "enormous energy contribution" and at this time are at a distance of just a few hundred meters from the sea . Also, the emission center that was reactivated a couple of days ago continues with an intermittent but much lower activity.
The technical director of the pevolca, Miguel Ángel Morcuende, has indicated that the primigenia pouring is still fed "very weak"; However, the laundry that is closer to the mountain of La Laguna has a "enormous contribution of energy", as well as the laundry located further north and from which a "very thin" appendix emerged, of just 5 meters Wide.
Is cast, as explained by Miguel Ángel Morcuende, is moving towards the south and the forecast is that he rejoices that he is closer to the mountain of La Laguna, which has continued to evolve in the direction of the west and at this time it is a A distance of about 200 meters from the sea.
As with the primal laundry, when the lava comes in contact with the water of the sea, small explosions and detachments of hydrochloric acid will occur, so that Morcuende has warned that before this occurs, civil protection measures will be applied, As can be the confinement of the neighbors of the area.
The affected surface is maintained at 724.95 hectares, since there are no updated data, and the maximum width between the castings is approximately 2,350 meters.
The technical director of the pevolca has also pointed out that seismicity is still maintained in the same area as in the previous days and in front and deep depths, so "there is no excessive concern" in this regard. Something similar happens with deformation, which has remained stable and has even dropped with previous days.
From the report of the scientific committee of pevolca emerges that the fisultural eruption continues to show the stonbolian mechanism and the volcanic explosive rate (Vei), in the case of this eruption continues until now in 2.
This Saturday there were several observable collection events of punctual ash in the ravine of Tamca, in the plain of the flies and on the Volcano de Martín. The spokesman for the Scientific Committee, María José Blanco, pointed out that these events do not indicate the opening of new emission centers, although it is not ruled out that some emission centers continue to appear in the environment of the current eruptive center and within the exclusion zone.
The height of the ash and gase column measured today is 4,200 meters, as well as its dispersion, and in terms of meteorological conditions, continues a defendant thermal investment with a very low base, about 300 meters away, and With weak winds with predominance of the breezing regime. In addition, the Saharan powder entry is causing an increase of PM10 particles, which will be referred from day 19. María José Blanco specified that unfavorable meteorological conditions will be maintained from the point of view of air quality and investment is expected to be Go back up and recover values of this time of year around 21 and 22 October.
Currently, the winds of south and west component are arranging the ash cloud and sulfur dioxide (SO2) to the north and northeast from the eruptive focus. This position is affecting the operability of the airport of La Palma and a stratum of airspace between La Palma, the north of La Gomera and Northwest Tenerife. It is expected that the wind turn to this component during the next dawn and this would mean a better scenario for the operability of the Mazo Airport.
Seismicity continues to be located in the same environment, with intermediate depths, between 10 and 15 km, and greater than 30 km. The high values of the amplitude of the seismic tremor, with pulses of intensification are maintained. The maximum magnitude observed on yesterday was 4.3 MBLG of an event 35 km deep and that was sense with IV intensity. They are still probable, given the levels of seismicity, more earthquakes felt by the population and that in areas of marked slopes can produce small landslides.
The deformation shows a stability pattern in the environment of the eruptive center. As for measures of sulfur dioxide in the Sabbath's plume, they are 8,278 tons per day, which is an underestimated value, and regarding the diffuse emission of carbon dioxide (CO2) by the Summit Travel building has been estimated In 992 tons per day.
The combination of measures carried out on day 14 with optical sensors allows to know the emission of other volatiles to the atmosphere by this eruptive process, reaching 43,000 tons per day of CO2, 2,360 for hydrochloric acid and 490 for carbon monoxide.
Regarding the quality of the air, during the early morning and early Saturday, high values of SO2 were measured in Puntagorda and Fuencaliente, but they did not exceed the timetable thresholds, and from that moment it was reduced to low values during the rest of the Day and Sunday morning. In the rest of the stations, low values were recorded throughout the day.
In relation to PM10 particles, the values measured in the set of the seasons were increasing throughout yesterday coinciding with the entry of a Saharan air mass, which has led to overcoming the daily threshold in the seasons of the plains, the pillar and the grass. But also on yesterday, the daily threshold of PM10 was exceeded in other seasons of the air quality measurement network in other islands, with similar values, so the exceptions that occurred in the palm are related to the air intake Saharan.Updated Date: 17 October 2021, 20:58
