The volcano of La Palma confirms its downward trend, with an emission of sulfur dioxide in the plume confirming that the eruption is losing energy. Although the values ​​are decreasing or decreasing, the spokesperson for the scientific committee of the Canary Islands Volcanic Emergency Plan and director of the IGN, María José Blanco, has advanced that this does not mean that the eruption will end “in the short term».

There is a decrease in all parameters, except for a rebound in the tremor signal observed since yesterday Monday at noon that will be “watched” in the next few hours. For its part, seismicity has decreased in its intermediate zone in number of earthquakes and magnitude, as well as the deep one, which has had a maximum of magnitude 3.8 to 38 kilometers deep.

The sulfur dioxide associated with the plume has been between 3,000 and 3,500 tons per dayBut Blanco has insisted that this trend is “slow” and requires it to reach even lower levels. The volcano “will go out at some point”, said the director of the IGN and although it is in a “more stable” phase and with a lower level, “in the short term it will not end” the eruption.

Regarding the surface affected by the lava, as pointed out by the technical director of Pevolca, Miguel Ángel Morcuende, it has grown in some fillings in the pouring zone 2, and progresses in the fajana, which has added (1:15 pm Canarian time) a new point of contact with the sea and already has a dimension of 42 hectares. The maximum width between flows has increased in relation to this new lava-sea connection point and amounts to 3,200 meters at the casting distance at its lowest elevation

The surface condition has damaged 1,462 buildings, 1,181 of them for residential use, according to the cadastre data. The Copernicus satellite brings this number to 1,042 hectares and 2,618 buildings. The cultivation area destroyed by the lava is of 305.59 hectares, 10 more than in the last report and mainly of banana type.

Ash rain

Air quality remains a concern, although the force of the winds has displaced the ashfall to the east side of the island, affecting the airport in the early hours of this Tuesday 16. It is especially worrying that the weight of the ash and the rain deposited on the greenhouses collapse some structures, as happened yesterday afternoon in the Charco Verde area.

With regard to sulfur dioxide, “high concentrations»With hourly and daily exceedances at the Los Llanos and Puntagorda stations.
