[BlownChevelle]

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...

[Mears]

Would a tsunami from this quake impact Hawaii?

Being reported now as 7.8, no damage reports seen yet. Hokkaido is not very heavily populated, and quake pretty far out at sea, so probably the worst would be the tsunami if there is one.

Wouldn't you be :-{P

It's my observation that whenever an earthquake occurs the other side of the world has one too. Usually within three days. Bye-bye Jellystone Park!

[Dog Gone]

That's an awfully deep earthquake, over 110,000 feet below the ocean floor.

It's the shallow ones that are most dangerous.
