plausible source, and also report that there is no indication that the tsunami propagated beyond Gran Canaria. These deposits date from between 32,000 and 1,750,000 years ago. Scientists at TU Delft in the Netherlands reported in 2006, that the section of the western flank of the Cumbre Vieja that was conjectured as potentially failing and falling into the Atlantic Ocean to create the hypothesised La Palma mega-tsunami was both too small in mass and volume, and far too stable to break away within the next 10,000 years. A 2008 paper looked into this very worst-case scenario, the most massive slide that could happen (though unlikely and probably impossible right now with the present day geology). They find wave heights in the range in the Canary Isles themselves. But the waves interfere and dissipate as they head out into the Atlantic. They predict a height of for some nearby island systems. For continents, the worst effects are in northern Brazil (), French Guiana (), Mid-Atlantic United States (), Western Sahara (largest prediction at ), and Mauritania (). This is not large enough to count as a megatsunami, with the highest prediction for Western Sahara comparable to the Japanese tsunami, so it would only be a megatsunami locally in the mid-Atlantic Ocean.
