Mega Tsunamis, Iminami
A Mega Tsunami is the giant version of the Tsunami. Mega Tsunami's are not caused by earthquakes, like Tsunami's, but initiated by massive landslides or enormous meteor impacts. In this BBC documentary places are visited where Mega Tsunami's occured in the past (Alaska Lituya Bay, Italy Vajont dam, Washington Spirit Lake). Also places are investigated where massive landslides are expected in the future. One of the most risky places is the Canary island La Palma. In the future scientist expect a massive landslide of the volcano Cumbre Vieja. It wil start a giant Mega Tsunami that possibly wil destroy cities on the West coast of the United States.
