Mars once featured a vast ocean that covered its northern hemisphere. New evidence suggests this Martian sea experienced at least two “mega-tsunamis” that were triggered by meteor impacts. Traces of these cataclysmic events can still be seen on the Martian surface, and they could still contain traces of ancient life.
On March 11, 2011 one of the strongest earthquakes ever recorded was epicentered off the coast of Japan. But most of the devastation—including many of the over 15,000 deaths—was due not to the shaking but to the powerful tsunami waves that traveled up to six miles inland.
Scientists have just uncovered one of the largest tsunami events in the geologic record, and naturally, it started with an epic splash. 73,000 years ago, the eastern flank of Cape Verde’s Fogo volcano collapsed into the sea, kicking up an 800-foot wave.
The discovery of a massive debris pile in a giant sinkhole in the Hawaiian islands suggests that the region was hit by a mammoth tsunami about 500 years ago. It was larger than any in Hawaii's recorded history, so scientists are now worrying that a similar disaster could happen again.
Last year's earthquake and resulting tsunami in Japan left scientists baffled. They knew that the potential for large waves was very real, but the tremendous size of the Japanese tsunami went beyond their wildest expectations — with some waves reaching as high as 20 feet. But now, scientists at Cambridge University…
Tucked away in the 8th volume of Herodotus' Histories is a reference to a town that was saved from attack by the Persians when the sea retreated — then returned higher than ever, drowning those who tried to cross the shallows. This account of 479 BCE is regarded as the first historical reference to a tsunami — and now…
Mark Demma recorded this amazing footage from Emeryville, California of the Japanese tsunami coming through the San Francisco metropolitan area.
The initial impact of a tsunami is dramatic, but the long-term effects of such flooding can be just as devastating for survivors.
At 2:46 p.m, Tokyo time, an 8.9 magnitude earthquake off the northeast coast of Japan sent a powerful wall of water inland, destroying coastal towns and property.
Imagine a life of almost complete isolation, spent on a barren island constantly hit by a mix of volcanoes, tsunamis, and long, brutal winters. For thousands of years, that's what people have endured on the Kuril Islands, an archipelago stretching from Russia to Japan that just might be the most extreme place humans…
