“The end of this eruptive process is not in sight in the short term, about two weeks,” he explained. Nemesio perez (Involcan) a Radio Television Canaria asked how long the rash might last. Pérez has been based to make this prediction on a key data: the amount of sulfur dioxide emitted by the volcano and which today is between 4,000 and 5,000 tons per day. For Pérez, until the record is lowered to 50 tons, the process cannot be terminated.
The calculations of the amount of lava emitted by the La Palma volcano vary between 39.6 and 60 million cubic meters (m3) depending on the measurement system used, a variation that highlights the difficulty of having a exact figure.
This was revealed this Sunday during the press conference after the one after the Scientific Committee and which was attended by the technical director of the Canary Islands Volcanic Emergency Plan (Pevolca), Miguel Angel Morcuende; and the director of the National Geographic Institute (IGN) in the Canary Islands, Maria Jose Blanco.
Precisely Blanco pointed out that Involcan stated in today’s meeting that the value of the magma expelled from sulfur dioxide emissions reaches 39.6 million cubic meters.
To highlight the difficulty of reaching an exact data, he observed that the estimated value through a satellite measurement raises the figure to about 60 million cubic meters. “There is a dance of figures that at this time it is not possible to confirm,” he clarified.
Air quality is reasonably good
In this regard, the director of Pevolca has explained that the air quality on La Palma is reasonably good as the maximum thresholds for sulfur dioxide and the size of the suspended particles are not exceeded.
In total, he explained that the area affected by the volcano is already 525.77 hectares –33.02 more than yesterday–; that the maximum width after the rupture of the northwest cone this night amounts to 1,520 meters; and that the strip occupies about 34 hectares of land.
In addition, Morcuende explained that of the 1,281 infrastructures damaged by the lava, 1,186 have been destroyed and 95 have suffered damage.
On the runoffs, after the destruction of the cone, several of these new emissions have taken place, the one located further to the northwest being practically braked.
Meanwhile, the second one that is more to the northwest has activity and two branches; the north branch, which is at the height of the Cementera, advances at about five meters per hour -a minimal advance-. “But we are monitoring it because it can reach the head of a mini-basin and vary the route, which could create some complication that would entail taking new civil protection measures,” he said.
Finally, in the lower part, the other branch has already passed the LP-213 road and the forecast is that it will go parallel to the previous one and look for an exit in the north of the Todoque mountain pushing the old arm that has been stopped for days .
