I just got an EDIS alert that there was an 8.0 quake near Hokkaido, Japan. Tsunami warnings for AK. No news sources yet that I can find...

This doesn't sound good.

[Mears]

Yikes!!!

[The_Victor]

That's a huge friggin' earth quake. I hope this is an error.

[July 4th]

That's a biggie.

[BureaucratusMaximus]

You OK?

[AmericanInTokyo]

A light "6" on the Japanese scale, though.

Out in the ocean, up near Hidaka.

[Sloth]

That's big.

[Lunatic Fringe]

8.0 is HUGH! Very series!

I'm going to take a shower.

[B Knotts]

I don't see anything like that yet.

[MineralMan]

Uh-oh. Tsunami warnings? A Japanese quake of that magnitude could mean tsunami warnings for the entire west coast of the US, depending on the quake's location and depth.

I'm going searching.

Terrific work TomGuy.

[BlownChevelle]

That one was yesterday...

[AmericanInTokyo]

This occured exactly 29 minutes ago. They are sounding the tsunami warning up in Hokkaido. (Think geographically if Tokyo were Atlanta, Georgia, then Hokkaido would be Rhode Island).

Pretty far from Tokyo.

5 mins since you posted this, and nothing on Reuters, my bloomberg terminal, FOX or CNN. I'm thinking this is a hoax.

[Dog Gone]

Nothing on this at the USGS site yet.

[Shermy]

That's not it.

[AmericanInTokyo]

Pull that one, please.

For Pete's sake, Western Honshu is on the other side of the archipelago from Hokkaido.

That is from two days ago. It is now Friday a.m. in Japan.
