TOKYO (AP) -- Japan's Meteorological Agency issues tsunami warning for country's east coast after magnitude 8.3 earthquake in northern Japan.
TSUNAMIS ARE A SERIES OF WAVES POTENTIALLY DANGEROUS
SEVERAL ==> HOURS <== AFTER INITIAL ARRIVAL TIME.
The weather channel barely mentioned it.
A TSUNAMI HAS BEEN OBSERVED AT THE FOLLOWING SITES
HANASAKI JAPAN 0.1M/0.3FT
WAVE OBSERVATIONS ARE THE AMPLITUDE ABOVE SEA LEVEL.
yes, I understand that, but I was quoting NOAA's prediction/time frame for waves action in Hawaii, should they begin there.
There wasn't anything more than that and the typical "Stay tuned".
The most recent estimates of magnitude:
Noaa says 8.2
USGS says 7.9
TSUNAMI MESSAGE NUMBER 002
PACIFIC TSUNAMI WARNING CENTER
0743 PM HST 12 JAN 2007
TO - CIVIL DEFENSE IN THE STATE OF HAWAII
SUBJECT - TSUNAMI WATCH SUPPLEMENT
A TSUNAMI WATCH CONTINUES IN EFFECT FOR THE STATE OF HAWAII.
AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS
ORIGIN TIME - 0623 PM HST 12 JAN 2007
COORDINATES - 46.7 NORTH 154.4 EAST
LOCATION - EAST OF KURIL ISLANDS
MAGNITUDE - 8.2 MOMENT
MAGNITUDE - 8.1 RICHTER
BASED ON ALL AVAILABLE DATA A TSUNAMI MAY HAVE BEEN GENERATED BY
THIS EARTHQUAKE THAT COULD BE DESTRUCTIVE ON COASTAL AREAS EVEN
FAR FROM THE EPICENTER. AN INVESTIGATION IS UNDERWAY TO DETERMINE
IF THERE IS A TSUNAMI THREAT TO HAWAII.
IF TSUNAMI WAVES IMPACT HAWAII THE ESTIMATED EARLIEST ARRIVAL OF
THE FIRST TSUNAMI WAVE IS
1223 AM HST 13 JAN 2007
MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

Only seconds ago USGS revised their magnitude upward to 8.2 (from the old one of 7.9)
So now the USGS and NOAA estimates are both 8.2
Report on yahoo saying tidal levels had fallen 4 inches in Nemuro, Japan, a sign of a possible tsunami.
USGS just upped it to 8.2
Wait and they will change again ;-)
Thing to remember about Tsunamis is they don't spread equally in all directions - you basically get two "beams" extending perpendicular to the fault...
Which is why the Tsunami from the last Kuril quake was higher in Crescent City CA than it was in Japan.
Truly remarkable to have a couplet of 8+ mag quakes so close to each other in time and space.
Anchorage is basically invulnerable to tsuamis. There was no Tsunami damage in Anchorage from the second largest quake ever recorded in 1964 that was just offshore, one that caused a massive tsunami in other areas of Alaska.
It's not reloading now.
that's ok, I have two cousins who work for NOAA - one in Hawaii handling this stuff, and another with earthquakes. They keep me straight too.
