The eruption of the vulcano Cumbre Vieja on the island of La Palma, in the Canary Islands, has reached its 33rd day of activity, with two lava flows which are destroying part of the La Laguna resort. However, their progress has slowed down in this direction and, after joining, they seem to take a direction that takes them away from La Laguna. Another lava flow is getting closer and closer to the coast: now it is alone 60 meters about from the cliff and then from the sea.
Marine geologist María Gómez spoke about the effects of lava on the seabed: “from 40 meters to 120-140 meters deep, the ecosystem is buried due to the advancement of the flow. Beyond this depth, there is a partial burial of the ecosystem. The new marine surface, which is the delta formed by the lava, will take some time to be re-colonized but the effect on the marine ecosystem is localized in the areas where it is located. It is the difference that we observe in relation to what happened with the underwater volcano El Hierro, whose brutal acidification of the waters has practically destroyed all the ecosystem and life. Recovery will be faster than expected compared to the El Hierro submarine volcanic system”.
I’m already over 886 the hectares of land affected by the lava e 2.122 buildings destroyed, according to data from the European Copernicus program. The volcanic ash, on the other hand, has covered 6.800 hectares. I’m over 7.000 the displaced.
In the course of the morning, dozens of earthquakes were detected on the island of La Palma. Most of the tremors had a depth between 9 and 15km, with a minimum magnitude of 2.6 and a maximum of 4.2, in the municipalities of Fuencaliente and Villa de Mazo.
During the eruption, moreover, they were observed at least quattro “volcanic flashes “, a phenomenon generated by the “Friction between particles” that “Needs more explosiveness than usual“: This was announced by the Spanish State Meteorological Agency, adding that these flashes were recorded on 13, 15 and 16 October.
