A very deep earthquake, but still quite strong.

The last 24 hours have seen a string of 4. Earthquakes but no more than usual at the depth they are happening. The one in California was less than 4.0 but still 8km deep.

Here's the warning quake data from Hokkaido. Happened on the 15th. 4.5 quake Oct. 15th @ 8:23utc

Theres also this one that caused a tsunami - www.abovetopsecret.com...

Yeah ive noticed a lot of activity. southern asia was going crazy for a little bit but that seems to have cooled down. 8km's is very shallow for such a densley populated area, hopefully its not a preshock

cheers for that..im thinking we may see a few aftershocks for this one.

Man these people could do with a break. I've been so impressed with the Japanese after watching them deal with disaster after disaster.

Atleast its not a big one


and it doesnt have to mean that a big earthquake is about to occur now just becuase the one earlier this year also had a "pre-earthquake"

They really haven't stopped shaking..I feel for them

Well, if you didn't know already - Something like half of Japan is under the Pacific already anyway from pre-historic quakes. A quick "googling" on "underwater Japanese cities" will help you.

To be honest I don't know how to take your post. It seemed snarky... It also didn't really make sense to me as a reply to y saying that I was impressed with the Japanese people and their ability to deal with catastrophes.

ok Ill bite. I did the google and see where there is an underwater pyramid, but please direct me to where half of Japan is underwater.

A single 150m x 40m site with no conclusive evidence of human occupation a thousand km south of mainland Japan is hardly "half of Japan".

And the fact that it's location (ie. under the sea) is almost without reservation attributed to rising sea levels after the last ice age as opposed to cataclysmic earthquakes might be something for you to consider.

Anyway, this quake is cause for a little concern, as it's right on the edge - quite literally - of the Daisetsuzan volcanic group. If one of the 20 volcanoes in that group are waking up... damn. I don't even want to think about what that will mean.

That area of Japan tends to be quite quiet as far as quakes go. Just take a look at the seismic history plots on the USGS page - it's one of the only parts of Japan that you can see clearly on the map. Maybe a dozen 4s and 5s since 1900. To my eye, it's the largest in that immediate area since 1900.

Worth keeping an eye on this one.

My apologies. Ive been watching too much Ancient Aliens.

7.4 in Kermadec, 7,2 in Turkey, 6.2 in Japan

1000 dead in turkey alone.

any deaths in Japan?
