The lava flow number 2 caused by the eruption in Cumbre Vieja, La Palma, has overflowed this Tuesday causing an advance on that front. This has been communicated by Francisco Prieto, member of the Technical Directorate of the Volcanic Emergency Plan of the Canary Islands (Pevolca) in the press conference after the meeting of the scientific committee on the evolution of the volcanic process on the island.

This advance of the lava has caused it to begin to fall this morning by the cliff on the beach of Los Guirres, right next to the fajana that began to form the original lavage more than a month ago. However, Prieto has specified that this front has “too much to fill” to reach the sea, from which it is separated by about 50 meters, so he does not believe that this contact will occur today.
Prieto has detailed that the lava that comes out of the volcano in Cumbre Vieja has fed in the last hours to streams 1, the one that formed the delta, and the 2, the one that has reached the beach of Los Guirres, and that both had practically a month without receiving a “visible contribution”.
In the original lava flow, this contribution of lava was “probably” being channeled up to now through volcanic tubes.
The rest of the flows remain “stable”, said Prieto, who has specified that the affected area has increased in the last 24 hours by 3.42 hectares, to 988.27.
Prieto has also detailed that the maximum width between the extreme points of the flows remains at approximately 3,100 meters, although within this extension there are areas that have not been affected by the lava.
The director in the Canary Islands of the National Geographic Institute (IGN), María José Blanco, has indicated for her part that the eruptive process has entered a “more stable” phase but that stability has to be maintained “for a certain time” and even diminish ” in a gradual and sustained way “all the parameters: seismicity, deformation, tremor and gas emission.
In fact, he recalled that seismicity continues at lower levels than in previous weeks, this is with earthquakes located between 10 and 15 kilometers and more than 20 kilometers deep, and this morning the largest recorded has been located at 3.8 mgLg, 38 kilometers, and has been felt with intensity III.
The height of the ash and gas cloud has reached 2,700 meters today and the gusts of wind, which can reach 50-55 kilometers per hour in Los Llanos de Aridane and El Paso, will cause a favorable situation for airport operations.
The sulfur dioxide emission from the plume ranges between 9,000 and 13,000 tons per day, in an evolution that also reflects a downward trend.
In turn, the diffuse emission of carbon dioxide associated with the Cumbre Vieja ridge varies between 1,700 and 1,900 tons per day, and María José Blanco has emphasized that these values do not represent a danger for the inhabitants of the affected areas.
However, air quality continues to be “regular” and yesterday at the Puntagorda station the alert threshold for sulfur dioxide was exceeded four times, and the hourly limit value nine times.
Regarding particles smaller than 10 microns, Francisco Prieto recalled that constant monitoring must be done to see how the situation evolves, because during the day it is usually extremely unfavorable and then there is a notable decrease at night.
In this regard, Francisco Prieto has indicated that in relation to air quality the recommendations set by Health are issued, but in the event of a worsening of the situation, the Pevolca steering committee could determine other measures, such as confinement, which in principle will not are being raised.
It did underline the need for ash cleaners to wear an FFP2 mask at all times.
Amílcar Cabrera, coordinator of the essential services group of Pevolca, referred to the beginning this Tuesday of the works for the new access road to Puerto Naos, again drawn up in parallel to the two current provisional roads, with a platform that will guarantee the transit of heavy vehicles and that will have an investment of 1,800,000 euros, and an execution period of one month.
Likewise, the Pevolca technicians have specified that 471 evacuated people are housed in hotels in Fuencaliente and Los Llanos de Aridane, and 47 dependents are in social health centers on the island.
