![]() Smart urban planning, to avoid the long-term risks of living on the flanks of a volcano, is entirely another. Intagliata: But, as he writes in his paper - predicting eruptions is one thing. 22, 2021 Lava from a volcanic eruption on La Palma, one of the Spanish Canary Islands, spread a path of havoc on Wednesday, destroying hundreds of homes, forcing the evacuation of. And we also see that it can accelerate very rapidly and in the end give a short warning for an imminent eruption. Longpré:In 50 years or maybe longer, when the volcano reactivates again, we will know from this current experience that it may take several years before the eruption actually shows up. CNN The Cumbre Vieja volcano in La Palma, one of Spain’s Canary Islands, erupted Sunday, after several earthquakes were felt over the weekend. ![]() Next time, Longpré says, forecasters will be better prepared. Blanco said seismic activity on La Palma island was now low but molten rock was still being thrown out of the volcano. Ĭumbre Vieja last erupted 50 years ago, in 1971. Intagliata:Longpré's analysis appears in the journal Science. So that's something that will be useful in the future for sure. Longpré: In hindsight it took a long time for the volcano to reactivate but in the end there was a week of late stage warning that an eruption was going to come. And the ground began to deform, likely due to flows of magma. But on September 11th, 2021 - eight days before the eruption - things picked up. In the years since, the volcano has triggered sporadic swarms of tiny quakes. Whereas Cumbre Vieja began to reawaken years ago, in October 2017, with a cluster of tiny earthquakes. Scientists are unsure how long this eruption will last. The Cumbre Vieja volcano on the Spanish island of La Palma continues to erupt, spewing lava and ash for more than a month now. ![]() We study this unrest along 2021 using Interferometric Synthetic Aperture Radar (InSAR) and. Intagliata: He explains that those volcanoes tend to have a shorter run-up to their eruptions. The volcano lies in the south of La Palma island, which is home to around 80,000 people. La Palma, Canary Islands, underwent volcanic unrest which culminated in its largest historical eruption. Longpré: One lesson is that volcanoes in the Canary Islands behave a little bit differently from other basaltic volcanoes we commonly see in the media for example, like Hawaiian volcanoes and Etna in Italy. He says every eruption helps scientists better understand volcanoes, and improve their forecasts. Intagliata: Marc-Antoine Longpré is a volcanologist at the City University of New York. Marc-Antoine Longpré: "It's always useful to see a new volcano personality." And volcanologists say the recent activity has them rethinking their predictions of the volcano's next move. The magma's movement underground has triggered clusters of earthquakes too- more than a dozen hit La Palma on a recent day.ĭespite that devastation, only one death has been attributed to the eruption. Rivers of lava have consumed at least 2600 buildings, and razed plantations of bananas and avocados. Christopher Intagliata: For three months now, the Cumbre Vieja volcano has unleashed fury upon the island of La Palma, in the Spanish Canary Islands.
