Canary Island volcanoes also erupt regularly-La Palma last erupted in 19-and slope stability analyses conducted at La Palma indicate that the structure is stable. These new simulations suggest that the maximum wave height along the east coast of the Americas from a “worst-case scenario” collapse of La Palma would be on the order of 1-2 m (3-7 feet)-still hazardous, but similar to common storm surge.Ĭollapses of Canary Island volcanoes are rare, occurring on timescales of hundreds of thousands of years, and should be preceded by signs of flank instability: increases in earthquakes and ground surface deformation. In addition, geomorphologists found, via slope stability analysis, that the potential collapse volume is much smaller than was simulated by the 2001 paper. Ocean floor mapping surrounding the Canary Islands, however, indicates that collapses instead occur in incremental or piecemeal fashion. Some papers have been published in the past in which. Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west. The Canary Islands “mega-tsunami” scenario assumed a single, coherent, massive collapse block that reached a high velocity very quickly. Cumbre Vieja volcano, located in La Palma Island (Canary Islands, Spain), erupted on 19 September 2021. An eruption at the Cumbre Vieja volcanic ridge, comprising the southern half of the Spanish Island of La Palma in the Canary Islands, lasted from 19 September. Tsunami risk for Louisiana: A mega tsunami will destroy Louisiana and the Gulf Coast if an underwater landslide occurred in the Mississippi Canyon. The Canary Islands Volcanology Institute likened one of the flows to a lava tsunami as the molten rock poured down a hillside. But is such a scenario possible or likely? Scientists have discovered that La Palma will collapse at the time of some future volcanic eruption on the summit of the Cumbre Vieja volcano. The recent eruption on La Palma, in the Canary Islands, has stimulated speculation that the volcano might collapse, creating a tsunami that would devastate the east coast of North and South America.
