The La Palma volcano emits a “small lava flow”, but the “signs of exhaustion” persist in the eruption

The scientific committee that monitors the eruption in Cumbre Vieja, La Palma, detected last Friday “a small flow” of lava on the surface over the flows that fall to the area of ​​cliffs of Las Hoyas, which corresponds to “a remnant” that proceeds of a volcanic tube still active, as explained by María José Blanco, director of the National Geographic Institute in the Canary Islands, after the meeting of the Volcanic Emergency Plan of the Canary Islands (Pevolca).

The volcanic activity is still stopped but “it cannot be considered finished yet”

The director of the IGN in the Canary Islands has emphasized that, in the absence of observable phenomena on the surface and those coming from the surveillance system, “the signs of exhaustion are corroborated”, without ruling out a rebound in strombolian activity and the emission of castings.

Blanco insisted that in order to terminate the eruptive process, the current levels of all the values ​​analyzed – seismicity, ground deformation, tremor and gas emission – must be maintained for another seven days.

On the other hand, the visible emission of volcanic gases is punctual and sporadic, concentrating in the area of ​​the eruptive centers and in the jameos of the volcanic tubes. In the walls of the main and secondary cone craters there are continuous “small collapses” in favor of existing faults and fissures, Blanco pointed out.

Specifically, in the diffuse emission of CO2 in the Cumbre Vieja building, levels 8.9 times higher than the average background value were recorded last Friday. Pevolca warns that in some areas of Cumbre Vieja these emanations may represent a danger for people if high values ​​are given in places without good ventilation or at heights from one meter below the ground.

Pevolca’s technical director, Rubén Fernández, has asked residents of the evacuated areas and irrigators to be “very aware” of the gases, to use FFP2 masks and not to remain alone “at any time.”

He has also asked them to comply “strictly” with the authorizations and authorized works / actions and to enter and leave the areas evacuated by the established control points.

Air quality in recent hours, in terms of SO2 concentration, has been good in all stations and for the fourth consecutive day yesterday there were no exceedances of hourly or daily limits.

Although this Saturday morning the values ​​are regular in Tazacorte and reasonably good in San Antonio.

Regarding the concentration of microparticles, in the Los Llanos station the values ​​are reasonably good, and in the rest of the stations, good.

“The tremor is at the level of background noise and the seismicity remains similar to yesterday at all depths. With the current level of seismicity, felt earthquakes are not ruled out,” explained Blanco.

The number of people housed in hotels is 556, one less than yesterday. Of these, 390 are in Fuencaliente, 73 in Los Llanos de Aridane and 93 in Breña Baja. The number of dependents housed in health centers remains at 43.

Persistent rains

The arrival is expected during the afternoon of this Saturday of an Atlantic front that will leave persistent and locally moderate rainfall until the early hours of Sunday morning.

The forecast is that with the passage of the front, “the southwest wind will be gusting with values ​​that locally can reach or exceed 60-70 km / h”, added Blanco.
