Traces Of Ancient 'Mega-Tsunamis' Discovered On Mars

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.

An Ancient Volcanic Collapse Triggered An 240 Metre Tsunami Wave

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 240m wave.

This Tiny Town Is Building A Groundbreaking Tsunami Shelter

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.

Vertical Tsunami Shelters Will Help People Get To Higher Ground, Fast

The threat of a tsunami is a very real thing for much of the Pacific coastline, yet many cities in the US 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 accessible safety in a second-story room.

A Timelapse Of All The Earthquakes From This Record-Breaking April

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.

Animation Explains How Tsunamis Form And Why They're So Scary

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.

Flood-Powered Gate Automatically Raises As The Waters Rise

Deploying the improved infrastructure that will hopefully help prevent future tsunamis from devastating Japan is an expensive endeavour. So researchers are developing new and cheaper ways to protect the country, like this innovative floodgate that deploys automatically when waters come rushing in — no power or human operators required.

Fish Sails From Japan To Washington On Unmanned Tsunami Boat

On an epic two-year journey across the Pacific, a bait box in a Japanese boat turned into an aquarium when five striped beakfish made it their home. The 6m fibreglass boat probably started off from Japan when the tsunami hit in March 2011.

Japan Turns Sole Surviving Tsunami Tree Into Gigantic Sculpture

Two years ago today, Japan was ravaged by a horrible tsunami. Now, there’s a new memorial dedicated to the tragedy: the “miracle tree” that survived the surge has now been converted into a sculpture.

US Military Tested A Tsunami Bomb That Could Rival The Nuclear Bomb

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 10m tsunami that would pulverise and drown a city.
