Scientists have studied this possibility for decades, particularly in Spain’s Canary Islands. The concern centers on Cumbre Vieja, a volcanic ridge on La Palma, where researchers have investigated whether a massive collapse of its western flank could displace enough ocean water to generate a tsunami. Unlike ordinary tsunamis, which are commonly triggered by underwater earthquakes, a volcanic landslide can push enormous amounts of water outward in a short period. If enough rock enters the ocean rapidly, the resulting waves can travel across entire ocean basins. An influential study published in 2001 suggested that a catastrophic collapse of La Palma could generate enormous waves capable of reaching coastlines thousands of miles away, including the eastern United States. However, subsequent research using more detailed geological evidence and improved computer models has found that the original worst-case estimates were likely exaggerated. Scientists now consider a single, enormous collapse much less likely than smaller landslides occurring over longer periods. Waves would also lose substantial energy while crossing the Atlantic, making the most extreme predictions for America’s East Coast unrealistic. La Palma remains volcanically active. Its 2021 eruption demonstrated how dramatically volcanic activity can reshape the landscape, destroying buildings and creating new land along the coastline. Researchers continue monitoring the island using seismic instruments, satellite measurements, and ground deformation data to understand its volcanic behavior. The important scientific question is not whether an Atlantic megatsunami is imminent. There is no evidence that such a catastrophe is about to happen. Instead, scientists are studying how volcanic islands evolve, why their slopes sometimes collapse, and how these events could affect distant coastlines.
