Experts have recently issued an urgent warning about tall tsunami waves that go over 1000 feet.

Sources shared how it was best to imagine this as a wall of water that runs up to a mile high, roaring across the ocean at hundreds of miles each hour.

The massive destructive forces behind this huge tsunami are just so hard to comprehend, some claim.

Unlike usual tsunamis that arise due to earthquakes, these mega tsunamis are usually triggered by massive landslides or collapsing volcanoes.

Three regions across America, including Alaska, Hawaii, and the West Coast, would be facing serious threats of mega tsunamis due to the proximity they hold to these unstable volcanoes, landslide-prone regions, and even some massive earthquake zones.

There is one dramatic example that was shared millions of years ago when one asteroid impact gave rise to a mile-high mega tsunami during the period of the dinosaurs, and it left traces that scientists would like to study.

Today, there's a huge possibility that the Cumbre Vieja volcano on the Canary Island of La Palma could collapse into the Atlantic and send out a huge tsunami towards the American East Coast.

The research suggests that the wave might start at 2000 feet high in the sky near the volcano and could reach up to 150 feet when it slams into America, posing a serious threat to the coastal region.
