Tsunamis are very probably the scariest natural disaster out there because they ravage everything in their path. But learning about how big they can get makes tsunamis even scarier. It’s just ridiculous. It’s like skyscraper big, man.
A magnitude 7.8 earthquake has rocked the Solomon Islands about 42 miles off the coast of Kirakira. A subsequent Tsunami watch was issued for Hawaii, but was canceled. Areas close to the quake are also on tsunami alerts.
A tsunami warning has been issued in Japan’s Fukushima Prefecture and Miyagi Prefecture after a 7.4 magnitude quake struck off Honshu at 5:59am local time. The US Geological Survey had a preliminary magnitude of 7.3 but then downgraded it to 6.9. It has been revised yet again to 7.4.
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.
On the coast of Washington, a small fishing town is working on a tsunami shelter that could protect more than half its population during a wall-of-water scenario. Hakai magazine explains why it works, while other communities have shut down efforts to fund shelters.
The threat of a tsunami is a very real thing for much of the Pacific coastline, yet many cities in the U.S. haven't taken specific infrastructural measures to ensure their residents are safe when they happen. A new building in Washington will have the first purpose-built tsunami shelter in the country, offering…
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.
Why were so many people shot in Chicago last weekend? Does today's earthquake in Japan mean another Fukushima meltdown? And why does Winnipeg want to fine people $100 for singing in public? These are the questions we address in this week's edition of What's Ruining Our Cities.
Didn't it seem to you that the ground was exceptionally shaky last month? That there were reports on big earthquakes happening somewhere pretty much every week? It wasn't just your imagination: April produced a higher-than-normal number of moderate-to-large earthquakes, and you can see it for yourself.
Waves come from the wind so tsunamis, which are basically bigger waves, must come from more wind, right? Not exactly. This cute animation explains that though normal waves are formed from above, tsunamis come from below from volcanic eruptions, landslides and earthquakes. They're the real monsters of the sea.
Deploying the improved infrastructure that will hopefully help prevent future tsunamis from devastating Japan is an expensive endeavour. So researchers across the country are developing new and cheaper ways to protect Japan, like this innovative floodgate that deploys automatically when waters come rushing in—no…
We've all seen the destruction that tsunamis can cause. It doesn't play around. But back in 1944, the US military wanted to play around with tsunamis in hope of creating a man made tsunami bomb—basically setting off 10 large blasts in the ocean to create a 33-foot tsunami that would pulverize and drown a city.
Inspired by the tragic tsunamis that hit Japan last year, Australian houseboat builder Matt Duncan decided to design and construct the ultimate life jacket. What he came up with was the Tsunami Survival Pod, designed to protect up to four passengers from rushing waters and tons of debris.
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…
A tiny village in Japan would've been wiped out by the tsunami had they erected their houses closer to the sea-views. However, they chose to abide by ancient tsunami-warning stones that carried the messages of their forefathers, and survived. Like an ancient message board.
The badly-damaged Fukushima Dai-ichi nuclear power plant has been upgraded from 5 to 7 on the International Nuclear and Radiological Event Scale. That's, in case you were wondering, out of seven. The only other nuclear crisis to reach the same… [Gawker]
