SANTA CRUZ DE LA PALMA, Sep 22 (EUROPA PRESS) –
The technical director of Pevolca, Miguel Ángel Morcuende, affirmed this Wednesday that the Cumbre Vieja volcano has entered a zone of “mini stability” that is not known how long it will last and although it is “quite explosive”, the lava flows They have slowed down and are moving very slowly, at 4 kilometers per hour, hence I have made no predictions as to whether it will eventually reach the sea.
In a press conference held after the meeting of the plan’s steering committee, he commented that the volcano has nine emission centers, four of them active and a single fissure, despite the fact that at first it was thought that there were two, and the Lava advances at 4 meters per hour and on Tuesday night it only traveled 15 meters.
He has said that the volcano continues to “release lava” and the flows progress “slowly” due to the increase in viscosity and the “filling” that it is making of certain natural holes, which are covered as it passes.
“The mathematical prediction we have is that it will continue to advance, but we do not know if it will reach the sea. We will have time to be vigilant if this event occurs because progress is very slow,” he indicated, although he specified It is not ruled out that the explosive episodes of the last days may be resumed.
Thus, he commented that despite this explosiveness, the deformation of the island “has not grown”, since it stands at 28 centimeters, 24 of which occurred in six 6 days, and the island is still on a red light due to a volcanic eruption.
Morcuende has also commented that the sulfur dioxide measurements “do not pose a health hazard” and the gas plume is at the highest point, around 3,000 meters.
THE AFFECTED SURFACE EXCEEDS 140 HECTARES
The affected area covers 140.44 hectares with a front of 600 meters and the lava reaches a thickness of between 8 and 15 meters.
Seismicity continues at low levels – today at 01.25 a magnitude 2.2 earthquake was located – and the estimate of the emission rate of sulfur dioxide (SO2) into the atmosphere by this eruptive process this Tuesday was between 6,140 and 11,500 tons per day.
The volcanic tremor signal shows a tendency to decrease in amplitude at seismic stations, probably due to the concentration of strombolian activity in a smaller number of centers.
ASHES CAN BE MOVED EAST
Regarding meteorological information, the anticyclonic situation continues, with winds from the northeast from the surface up to 3,000 meters, with intensities around 20 and 30 kilometers per hour.
The most significant thing is the turn of the wind from north / northeast to west increasing its intensity, which will influence the ash movement towards the east of La Palma.
In addition, it is ruled out that the precipitations that can be recorded during the next 24 hours are acidic.
If the lava flows reached the coast, the scientists warn that the interaction of the sea with the lava could generate columns of water vapor with acid gases, detachment of the lava front, and the emission of fragments could be produced in the vicinity of the contact (fragmentation snapshot and emission of ballistic fragments).
Morcuende has insisted that the volcano is being monitored at all times by scientists and with the support of institutions and asked for the collaboration of citizens so that they do not approach the exclusion zones because they are very dangerous.
“The best way to see the volcano is on television, so that citizens are not another danger and do not approach or collapse the roads,” he said, stressing that exposure can cause personal damage to the eyes and lungs.
