TOKYO (AP) -- Japan's Meteorological Agency issues tsunami warning for country's east coast after magnitude 8.3 earthquake in northern Japan.
Good luck Guam. One of the things that worried me when I worked in the Navy is whether a tsunami could suck out the caison of a drydock. I hope the people of Guam remain safe and the Naval Base there suffers no damages.
Fox 12 Portland Or just reported the tsunami wave was 1ft high in Japan and Alsaka.
Thank God looks like it is over.
Musta been that home canned tuna sanwhich I made.....tsunami squausher. : )
Oooh. That's not a good sign. Thanks for the info.
OK, well said then. I agree that tide stations are for scientists to determine the probable effects, not for casual observers and so we shouldn't be trying to get too much information out of that data without being properly trained.
Good info, thx
Like I was saying the nature of the wave propagation likely did not send the highest waves to the western Aleutians or to Northeast Japan - those locations are parallel to the generating fault and it's possible waves may be higher in locations perpendicular to the fault.
won't even hit Alaska for a few more hours
But Japan seems OK
Ohhhh I didn't know that.
Hence my tag line.
it already hit shemya alaska, only a few inches high though
oops, missed that:
SHEMYA ALASKA .06CM/0.2 FT

One tidbit for the many people that enjoy seeing scientists get egg on their faces...
This portion of the Kuril Trench where these two great earthquakes in November and then tonight occured was SPECIFICALLY singled out by a paper in Science in 2003 as an area where due to the nature of the geology of the trench in that area, it could not generate large earthquakes.
They even made a specific "negative" prediction that such quakes would never occur there, in 2004.
bump 4no wave
Hey!!! That there might not be gummint approved info!!
Russian Navy denies missile fuel leak
Thursday, January 11, 2007 Moscow, Jan 11 (RIA Novosti) An indicator failure set off a missile fuel leak alarm on board a nuclear submarine in Far East waters, but no fuel spillage actually occurred, a Russian naval official said Thursday.
A missile tube was sealed after an alarm system went off in a submarine docked at the Vilyuchinsk base in the Kamchatka region.
'Some media have cited various sources as saying that there was allegedly a missile fuel component leakage. This information is inaccurate,' said Igor Dygalo, an aide to the navy commander.
He said the missile was in proper condition and no oxidant leakage had been registered.
The wave heights are actually much smaller in Hanasaki, Kushiro, and Shemya for this quake than the one in November...
I'd suspect the warnings get dropped eventually.
On Wednesday, November 15, 2006 at 11:14:16 (UTC) a large (Mw = 8.3) earthquake occurred on the Kuril Islands Subduction Zone. The event caused a Pacific wide tsunami which was expected to reach Japan in 64 minutes and California in 8 hours and 20 minutes.
The first wave arrived at Hanasaki, Hokaido with an amplitude of 30 cm. After the observation of this minor tsunami in Japan, a large tsunami was not expected in Alaska or along the US west coast.
However, around 11 am PST, the Crescent City, California Harbor Control and Emergency offices received a warning for possible strong tsunami surges which were expected to arrive around 11:30 am. Because the tsunami effect was expected to be relatively minor, a full evacuation was not ordered, but rather targeted verbal warnings were issued for people in the harbor. Mr. Erik Macee from the fishing vessel 'Resolution' confirmed that he was warned by the harbor control at around 11:10 am.
The first wave arrived as expected but it was not noticed by the harbor control. Mr. Macee said he was in his boat when he first noticed the withdrawal. He was able to watch the tsunami from his boat looking at the water elevation change at the piling and breakwater.
The tsunami surges did not cause any damage until after 2 pm. Mr. Macee said the largest waves arrived around 2 or 2:30 pm. The second in the series of larger waves did the most damage when mooring lines from vessels berthed at Dock H were severed. Dock H had three boats, including the biggest boat in the harbor, 'Delana'. The 'Delana' was connected directly to the piling, while the other two vessels were connected to the exposed dock. The dock could not resist the strong current and the pull coming from the boats and failed
The current was so strong, harbor facilities manager Pual McAndrews reported that a white buoy at the entrance of the harbor was buried under water as the current flowed out of the harbor. He also noted that harbor seals and sea lions were not able to swim against the current.
Predictions are derived ex post facto.

The Frank Cable is currently tied up for heavy maintenance as we speak....
guess that's it good night
Thanks for confirmation. I never trust our local news :-)
Sorry if my message was garbled...This morning I received a message on one of my newsgroups that the California Office of Emergency Services EDIS site was not updating, as their new software had some issues. It appears to have been corrrected now.
the site is
It is a really good source, monitored by media and public safety officials statewide, and the messages are sent out over radio, internet, teletype, DirecTV, XM Radio, and probably some other outlets all at the same time....so if a couple fail, the msg will still get out.
Warnings are now cancelled everywhere

Mine came through as 7.7 on the cell for the second ping. First ping was raw data as 'greater than 7.5' - which means the system just doesn't know yet and is sitting there flickering an alarm for a seismologist to take a gander at the recordings.
Thank you for the pings Lijahsbubbe, Global2010, Mo1 and Onyx.
There was a 16 inch tsunami reported in Japan and a 12 inch tsunami reported in Shemaya, Alaska.
Sixteen-Inch Tidal Wave Triggered by Japanese Quake Hits Pacific Island
Earthquake Ping List. Please send a Freepmail if you want to be added to or removed from this list.
isn't it more a function of the degree of seafloor displacement that causes the wave and not shaking???
LOL Moon/earthquake remarks instantly make me think Lijahsbubbe. : )
This is a case of the pingees' pinging the pinger. : )
That is a gorgeous picture!
The simple answer is that water has to be displaced, and/or shoreline eroded for there to be a tsunami.
A major quake on a bad shoreline has the potential of causing the shoreline to slough off enough material that it changes the slope of the shoreline, displaces water and greatly increases the risk of a local tsunami.
Seafloor shifting from a major quake on a seafloor fault has the potential to create a tsunami, depending upon the location of the fault, the type of slippage, how far the plates shifted, the magnitude of the quake, etc.
Here's a very simplified graphic showing a tsunami, Chode.
My son finally came back from Japan but I know he was up North. Thinking of you w/ prayers.
Excellant example of what displaced water of a tsunami does.
Sure helped me grasp it even after all the education posted on tsunami events.
ROFLOL! Can you quickly say that 100 times?
One ping only.
Not me, clearly photoshopped, not my fault.......
It lloks like N. Korea may be affected! Quick, call all FAGS! Arex Barwinnn where are you!!!!
I just went to United Airlines, and calculated a trip from San Francisco International SFO to Osaka Kansai International KIX, and "Show Flight Details" says that the trip is 5413 "miles" [I assume that's standard miles, not nautical miles].
So if this "wave" is crossing the Pacific in about 8 hours, then it's travelling at something close to the speed of sound [600+ miles per hour].
I guess the speed of vibration in water must be pretty close to the speed of vibration in air - but man, I wonder what would that shock wave would look like if you could witness it?
Can you imagine a 16" ripple moving through the water at 600+ miles per hour?
I think I may start a new thread about this.
