On the Cape Verde Islands in West Africa, scientists have found footprints of megatsunami over 243 meters high, which arose 73, 000 years ago. According to them, a giant wave was formed as a result of the collapse of one of the slopes of the awakened volcano Fogo with a volume of 160 cubic meters into the sea. km of rocks. Upon reaching the neighboring island, she devastated it over a distance of more than 30 miles.
Recently, volcanologists have often discussed the catastrophic consequences of such collapses, one of which is a giant tsunami. According to Riccardo Ramalho, a researcher at Columbia University's Earth Laboratory, they happen very rarely, but they pose a huge danger.
Volcano Fogo is located at an altitude of 2829 meters above sea level and wakes up about 1 time in 20 years. The last eruption took place in the fall of last year. There are many similar volcanoes on our planet, the slopes of which can also fall into the ocean.
So in Alaska in recent years there have been about 10 such volcanic collapses, and Japan was no exception, periodically subject to "attacks" by devastating tsunamis.
To imagine the size of the prehistoric tsunami - 243 meters - it is enough to remember that the height of the Eiffel Tower is 324 meters, and the Statue of Liberty is “only” 93.
