Hawaii also has a tsunami watch but the wave is not expected to be high there.

Above is where the epicenter of the 7.8 quake was,where the red box is at graphic.

[Extremeweatherguy]

Just heard on the news that it's magnitude was upped to an 8.1 and that parts of Alaska now have a tsunami warning out too!

[P.K.]

The initial report from the JMA was a 8.1.

Here is the warning map from an hour ago.

More information here

The readings varie from 8.1 to 7.8 but those are preliminary.Later today they will reveal the exact magnitud.But regardless being 7.8 or 8.1 are strong quakes anyway that can cause extensive damage.Thankfully this area is not a dense populated one.

The greatest threat of a significant tsunami is really to the Japan. This is not to sound the all clear but with nothing being report so far, I think we are looking good again this time.

Tsunami Advisory issued earlier for the US West coast. No damaging Tsumami expected:

The good news is that the 2 tsunamis were not very tall and hit in sparse populated areas.Also no reports of casualties at this time.

EVALUATION

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER AND
COULD ALSO BE A THREAT TO MORE DISTANT COASTS. AUTHORITIES SHOULD
TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS
CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE
EXTENT AND SEVERITY OF THE THREAT.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

WOW... 16 inches, everyone run.

WOW... 16 inches, everyone run.

They cannot tell until the wave hits the coast.

[Hybridstorm_November2001]

True. This just illustrates how poor our scientific knowledge is of the mechanisms behind the creation, and sustainment of tsunamis. We still have a lot to learn. I only hope, and pray, that we learn some of it before the next major event occurs.
