They're saying 8.4.
Prayers....
So who do you think is right?
The USGS that says 7.7 magnitude, or the noaa tsunami people who say 8.4?
Are there any reports of damages on land yet?
Prayers up for anyone in the possible path.

Hokkaido on alert after 7.7-magnitude quake strikes off Kuril Islands
TOKYO - A tsunami warning was issued on Saturday for the eastern part of Japan’s northernmost island of Hokkaido and a lesser warning for a wide swathe of northeastern and eastern Honshu, Japan’s main island, NHK public television said.
The earliest possible arrival of the tsunami was estimated at 2 p.m. (0500 GMT) on the eastern coast of Hokkaido with an estimated maximum height of one meter.
The warning came after a 7.7-magnitude earthquake struck to the east of the Kuril Islands. The quake rocked parts of eastern Hokkaido and northeastern Honshu. There were no immediate reports of injuries from the earthquake.

"An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines near the epicenter within minutes and more distant coastlines within hours," the bulletin said.
It's on every TV channel in Tokyo. Pacific and north coast of Hokkaido in red, the entire coastline of Honshu down to Osaka in yellow.
Didn't feel the earthquake though.
They just issued the second tsunami warning update from the pacific tsunami center.
It shows the new magnitude estimate of 8.2 from noaa, and hawaii is still on the tsunami watch list
There wasn't anything more than that and the typical "Stay tuned".

question(that may already been asked/answered) isn't it more a function of the degree of seafloor displacement that causes the wave and not shaking???
