For the islands en.wikipedia.org...

In 2006 they had a 8.3 that caused 5 foot tsumani waves reaching California

The Kuril Islands form part of the ring of tectonic instability encircling the Pacific ocean referred to as the Ring of Fire. The islands themselves are summits of stratovolcanoes that are a direct result of the subduction of the Pacific Plate under the Okhotsk Plate, which forms the Kuril Trench some 200 km east of the islands. The chain has around 100 volcanoes, some 40 of which are active, and many hot springs and fumaroles. There is frequent seismic activity, including an earthquake of magnitude 8.3 recorded on November 15, 2006, which resulted in tsunami waves up to 5 ft reaching the California coast.

No, I haven't heard about this! I will keep a check on that. Great find! Keep us posted.

I'm out in Eastern Hokkaido today, and I felt it. Nothing out of the ordinary, though. The Tv news said it was a 6.6, and that's what yahoo.jp has it listed as. When I checked the usgs site it was there as well, but it looks like it's been upgraded.

This is, believe it or not, perfectly normal for the Kurils. That area gets about 4 quakes over 6.9 per year.

No tsunami warning has been issued as far as I know. the sirens would be going if that were the case.

I'd be surprised if there's any damage from this one. The islands near the epicentre are pretty much uninhabited, and the population centres that were affected are pretty used to large quakes, as I mentioned. Buildings that aren't built to take quakes don't last very long out here. It's kind of an architectural "survival of the fittest".

Summary: Yep. It was a quake. No Worries.

I saw that too

It was posted in that Italy EQ thread. If you watch something long enough it changes. Are we watching too much?

West Coast and Alaska Tsunami Warning Center reports NO Tsunami expected. The 6.8 quake was at 9:24 pm pacific daylight time 4/6/09

thats a big one. imagine if something like that had it italy, could hav been much worse.

I thought about creating this thread but I saw someone had already posted about it in the Quake Watch thread: www.abovetopsecret.com...

The magnitude has been revised...

I wouldn't be surprised if it's upgraded once more. The Japanese quake data still has it as a 6.6. USGS had it as a 6.7, then a 7.0, now revised again as more data starts comes in.

Here's an interesting link - quakes in the area from 1990 - present:

See what I mean about the area being used to quakes?
