The Director of the Geosciences Barcelona, CSIC, the Vulcanologist Joan Martín, has highlighted that the volcanic eruption that this Sunday has occurred on the island of La Palma is "normal", of which there has been historically in Canarias, and added That, by the data you have, it could last at a couple of months.
Joan Martí has indicated that it is a stonbolian eruption, of little evolved magma, in which the biggest problem can be the gases that come out with magma.
Lava possibly reaches the sea, as has occurred on other occasions in La Palma, and Joan Marti has considered that the duration of eruption can be a couple of weeks but also a couple of months.
The greatest or lower rapidity of the progress of the castings will depend on the viscosity of the lava, that is, its composition, and apparently so far it is more fluid than in other volcanoes, but not as much as in those of Hawaii. The castings that are being observed in La Palma have the dark and dense aspect of the classic "Malpaís" of the Canary Islands.
The advantage of this situation is that it is eruptions that, in principle, do not entail danger, due to the fact that the lava is relatively slow and its area of action is not very large and, above all, because it is channeled by the topography , Which is an advantage, Joan Martí explained.
He has commented that the explosive part is not very important in this case and the little piroclast that is observed will accumulate in the exit zone.
The only problem can be the gases that escape with magma and that can be derived from sulfur and CO2, the last of which it is not noticeable, but it can cause breathing problems, Joan Martí has warned.
There could be another problem if there is any explosive phase of more intensity and that launch ash that runs a higher area and affect, for example, to the airport, but for that we have to wait to see evolution.
