Friday's earthquake off the eastern coast of Japan was upgraded to a magnitude 9.0 by the Japan Meteorological Agency, the Kyodo News agency reported Sunday.

The quake probably shifted the position of Earth's axis about 6.5 inches, said Richard Gross, a geophysicist at the Jet Propulsion Laboratory in La Canada Flintridge, in an e-mail.
The temblor also should have caused Earth to rotate somewhat faster, shortening the length of the day by about 1.8 microseconds, he said.

Already, just over 36 hours after the quake, data-crunchers had determined that the temblor's force moved parts of eastern Japan as much as 12 feet closer to North America, scientists said,and that Japan has shifted downward about two feet.
How much time between the quake and the evacuation warning was there in Japan?
I doubt this one will climb that high. The indian ocean one effected a much larger area and many of the places it took out were small rural villages with basically no infastructure. I have no doubt it will be higher than 10K but I don't think it will rise into the 100K region.
It is likely that we would get some kind of early warning such as high activities at Mt. St. Helens.I wonder what kind of death toll we will see here when the 9.0 one strikes us. Vancouver and Seattle are not at all prepared.
Unfortunately, the cities/areas destroyed by the tsunami were populated by over one millions people. With 11 minutes of warning, how many were able to get out safely?
True. It could be the case. I hope not but it does seem to just get worse and worse.
I heard that the first tsunami wave arrived in less than 10 minutes after the quake. I haven't heard anything about there being warnings sent out.
With all the talk of the Earth's axis changing with the last two big quakes, I wonder how it affects GPS? Not to mention, the coastal elevation and longitudal changes from the actual plate shifting.
not sure at this point if im still gonna be going to japan in late april... has air travel resumed and are trains back to normal around tokyo yet?
People are wondering how the water can travel so far and so quick inland. Way I see it, a tsunami isn't simply like a standing wave, with stuff bobbing up & down with little lateral movement. The ocean floor rises, displaces the water and the result is more like tipping a monstrous bucket on a floor. It has a wave (ripple) component but it acts like a gigantic spill across the coastline. There is a strong horizontal component to its power, both on the way in and when the water recedes into the ocean.
10,000 feared dead now, not just a thousand.
Umm...you *do* realize that "official count" is a nonsense figure at this point, right? There was a point when the official count was 1. You're finally looking at an estimate instead of an official death toll and you're thinking it must be "bullshit" because it's so much higher.
10,000 sounds ridiculously low to me.
More than 230,000 died in the 2004 tsunami.

One of the articles I was reading on them says they can reach up to 500MPH. My simple brain can not fathom the idea of that much water going that fast. I just can't. All I can do is look at the aftermath accept that it's quite possibly the most destructive force on the planet short of an ice age causing volcanic event.
On CNN they said the Japanese tsunami was traveling at 300-400mph and 30mph on land. That's just insane.
