A leading volcanologist has raised alarms over the looming threat of a cataclysmic event stemming from a volcano in the Canary Islands. The Cumbre Vieja volcano, situated on Spain’s La Palma island, is at the centre of discussions regarding the risk of major structural collapse into the Atlantic Ocean, which could unleash a devastating megatsunami. This natural disaster has the potential to inflict catastrophic damage on coastal populations, even thousands of miles from the eruption site.
Professor Bill McGuire, an expert in volcanology, has been closely observing the behaviour of Cumbre Vieja. He has indicated that a considerable segment of the volcano’s flank is gradually shifting toward the ocean. Speaking to *BBC Science Focus*, McGuire stated, “Based on extensive studies, I expect this part of the flank will eventually crash into the North Atlantic, launching a megatsunami in the process.”
The scientific community remains divided over the scale and impact of such an event. Reports suggest that computer simulations predict waves reaching heights of up to 20 meters (65 feet) along the US East Coast. If the volcano were to collapse, these colossal waves could inundate coastal regions as quickly as nine hours post-disaster. Strikingly, scientists have detected evidence of ancient tsunamis by examining massive boulders along the shores of the Bahamas—rocks that likely originated from past volcanic collapses in the Atlantic.
While the spectre of such a catastrophic event is concerning, researchers emphasise that a collapse of Cumbre Vieja is not an immediate threat; it could occur centuries, or even millennia, from now. McGuire himself stated, “I have no doubt this will be a cataclysmic event, but have no idea when it will happen.”
Cumbre Vieja last erupted in 2021, an event that lasted 85 days and led to the destruction of over 2,800 structures on La Palma, forcing thousands of residents to evacuate. The spectre of tsunamis becomes more tangible when recalling the devastating Boxing Day tsunami of 2004, which resulted in over 227,000 fatalities across 15 countries, underscoring the potential for widespread loss of life and property that such natural disasters entail.
In summation, while the possibility of a megatsunami originating from Cumbre Vieja remains theoretical, the awareness of its potential consequences serves as a crucial reminder of nature’s unpredictable power. Monitoring efforts and further research into this phenomenon are essential, as they could provide vital information for preparedness in the face of possible future events.
