Evidence of mega-tsunami found on Cape Verde

Scientists working in Cape Verde have reported that the collapse of the volcano on the island of Fogo 73,000 years ago caused a 240m-high tsunami, a wave more than eight times the size of the recent tsunamis in Japan (2011) and Indian Ocean (2004).

Several massive boulders, some up to 770 tonnes, were swept up in the wave and carried hundreds of metres up adjacent islands. The research team estimate that 167 cubic km of rock fell into the ocean during the ancient caldera’s collapse. Read more: theguardian.com
