A 50cm tsunami!?! Everyone had better lookout! Ditch the shores and follow the animals!

Here in Tokyo. Just felt it, it was a biggie.

Is that a joke? 50cm? Or is it 50 cubic meters?

centimetres.

Thats still enough to lift a truck and pull it into the ocean.

If 50cm was ocean swell height then you could see a lot more at the shore.... Yikes....

Apparently tsunamis aren't always all theyre cracked up to be.

Magnitude-6.8 earthquake jolts northern Japan

A 4-inch tsunami reached the Japanese shore about 15 minutes after the quake struck, NHK said, with no major damage immediately reported.

So how do they tell the tsunami apart from normal waves?

Waves tend to be more on the top of the ocean currents while a tsunami wave has most of its power at the bottom of the current. No?

But 50cm is barely 2 feet and most of Japan's islands appears to be far more than 50cm in elevation.

50 cm is almost 20 inches. If the land dropped off very steeply off the shoreline, couldn't that generate a fairly good size wave when it hit the shore?

Don't know. Just asking ...

The Tsunami effect [of the quake] is only a direct result of the overall shift in the [tectonic] plates. Big quakes do not, necessarily, mean big tsunamis. It's the vertical [+/-] movement of the tectonic plates that determines displacement.

Either way, it definitely represents substantial [sub] movement/disruption.

A tsunami, no matter how big, involves the water from the top of the ocean to the bottom moving, and pulls the water at shore WAY out to see before hitting. It exposes many things, and people go running out to see what shows up, which is one reason that even a small wave can be very dangerous. It will easily pull a full cement truck out to sea at 2 feet. It's a LOT of power and water volume moving.

why is this in the war on terrorism section?

Isn't 50 cms round like 19 inches? So really it could pull a really small car a lil ways, but I doubt any futher.

Two small Tsunamis occured. Both were around 10cm, so no big deal.

It was about Mag. 5 where I live. Biggest I have felt in a couple of years, but no damage or injuries worth talking about.

There are a dozen or so casualties reported from a ceiling collapsing into a swimming pool, but apart from that, everyone is well and the situation is under control.

According to my measuring device, 50 cm is about 20 inches.
