This is the award winning Megatsunami documentary written, produced and directed by Thom Goddard.
The island of La Palma in the Canary Islands is at risk of undergoing a large landslide, which could cause a megatsunami in the Atlantic Ocean. Volcanic islands and volcanoes on land frequently undergo large landslides/collapses, which have been documented in Hawaii for example. A recent example is Anak Krakatau, which collapsed to cause the 2018 Sunda Strait tsunami, claiming hundreds of lives.
Steven N. Ward and Simon Day, in a 2001 research article, proposed that a Holocene change in the eruptive activity of Cumbre Vieja volcano and a fracture on the volcano that formed during an eruption in 1949 may be the prelude to a giant collapse. They estimated that such a collapse could cause giant tsunamis across the entire North Atlantic and severely impact countries as far away as North America.
