![]() Petley points out that after the eruption of the Teneguía volcano in 1971, there were no signs of risk of collapse.Īlthough he does stress that it cannot be ruled entirely, and part of the slope could in theory detach and fall into the sea, but it wouldn’t result in the scale of disaster that Ward and Day suggest in their research.įirefighters watch the volcano Cumbre Vieja on the Canary Island of La Palma (Credit Image: © Arturo Jimenez/dpa via ZUMA Press)Īndrews argues that “For the Cumbre Vieja flank to meet conditions close to instability, an exceptionally high-magnitude earthquake and a large-scale explosive volcanic eruption would have to occur simultaneously, or the current volcanic building should reach at least 1,000 in its natural growth – meters more than the current maximum elevation. He found “no evidence” that a part of the volcano could be unstable. However there is precedent for such an occurrence.Ī volcanic eruption north of La Palma 560,000 years ago dumped 200 km3 of volcanic material into the sea and is thought to have caused an enormously damaging tsunami.ĭave Petley, an avalanche expert at Sheffield University, visited the Cumbre Vieja volcano in person in 2017 to test the theory. 4nAyGYrTyW- Dr Robin George Andrews ? September 20, 2021 Trouble visualizing that? How about this: these lava fountains are, at their tallest, almost doubling the height of the Burj Khalifa, the tallest skyscraper in the world. The lava fountains coming from the La Palma eruption are reaching heights of 1,000 to 1,500m. ![]() Their research theorizes that an erupting volcano on La Palma could become unstable, and if it were to collapse, between 150 and 500 cubic kilometers of volcanic rock could be sent hurtling into the sea, triggering a devastating tsunami.Īccording to the research “the waves could be up to 25 meters high, and would even cause damage to the south of England further north and then to the west they would reach the North American coast, as well as “destroy the West African coast with waves of up to 100 meters”. The much debated hypothesis is based on a single research paper published in 2001 by Simon Day, of the Benfield Greig Hazard Research Centre, University of London and Steven Ward, a professor at the Institute of Geophysics and Planetary Physics at the University of California. #LaPalmaeruption /twKjEutpAA- INVOLCAN September 19, 2021 The lava cools and the surface solidifies. We have calculated the approximate flow speed at the middle of the lava's trajectory is 0.7 km / h.
