Quake Watch 2007

With the comet and the surge, this week is shaping up to just be too damn strange to be mere coincidence. EMSC has the quake magnitude at 8.3 and USGS upgraded it to 7.9.

And CNN is quoting it as a 8.4...

USGS upgraded the quake to 8.2

According to RSOE Havaria there has been five 5.0 or higher quakes through Russia since the big one hit earlier today. Aftershocks along the same faultline maybe?

Tsunami's predicted to hit, and have hit, in several places.

Also an 8.3 just popped up on RSOE

Interesting times.

Make that 8 quakes in Russia over 4.5 in the past few hours.

^ The 8.3 was the original quake.

Ahhhhh, ok. I have trouble reading that map sometimes. Those circled in yellow are supposed to be the most recent. Go figure. Thanks.

Seeems tsunami warnings have been down graded,

TOKYO - Thousands of residents fled to higher ground after an 8.3 magnitude earthquake struck off Japan‘s northern coast in the Pacific on Saturday, setting off tsunami warnings.

A tsunami warning also was issued for Alaska‘s western Aleutian islands, prompting some residents to evacuate, and a tsunami watch was issued for Hawaii. Both were later canceled.

But the largest wave reported was a 16-inch tidal swell that twice hit the shores of Chichi-jima, a Pacific island 620 miles south of Tokyo, more than three hours after the quake.

I looks like 14 now on USGS including the first one.

There was an 8.3 in this location last November as well too:

earthquake.usgs.gov...

46.607°N, 153.230°E

Depth 30.3 km

Today's event:

46.288°N, 154.448°E

Depth 10km

on Google earth I get about 62 miles (100km) between these two quakes.

Oh and what do you mean by this exactly?

You can chart the progress of the Ring of Fire quakes moving from Fiji area north and then east over to Alaska.

Hi Apex: Check out the URL I gave in my post. It has a nice feature - it has a list of quakes in the last 30 days. You can check it as the reports come in. Anyway, check out that 30 day list (you can click on the button beneath map). Study it for the last week or so. You will find that there was a 7.2 quake in Fiji followed by numerous other ones 4.0 and above, all in that area. Next, notice that the earthquakes seem to be moving north. Last week, Fiji was the hot spot, now it's between Aleutian Islands and Siberia. Also, check out the vast amount of activity all along the eastern shores of South America. In short, the only spot not affected so much is Calif, Washington and Oregon. But to me, it looks like it's closing in on the Pacific Coast. There was also an 8.2 in China I believe about a week ago. Lots of high level quakes in the last 10 days or a week - which may mean that it's aggravated other plates enough to shift and keep on shifting for awhile. Today, the above 4.0 quakes have been all day long near the Kuril Islands, off the coast of SE Siberia, not too far from the Aleutians.
Hope that helps make it more clear. What do you think about all this Apex?

It's an interesting idea that, but I think you missed Malaysia or Indonesia, but there was the Tsunami generating earthquake there, which may mean that there will not be anything there. The San Andreas Fault is also transverse rather than a subduction zone. it is an interesting hypothesis though, So lets wait to see what happens. After all it is known (and accepted by some) that one event can affect places further away, so there may be something that happens.

According to RSOE there has been 50... yes 50 quakes in the exact same spot in the past 24 hours. IS THAT NORMAL??!?!

Where does it say 50? And USGS says there have been 29 there. I have no idea how many aftershocks is considered normal.

I might have miscounted, because i counted them myself, but it would be a big miscount.

Most have been 5.0 or higher as well.

There is no formula for how many aftershocks are normal for a particular size...each quake is different, each has it's own features, and each moves it's own way.

That being said, it is not uncommon to have thousands of aftershocks in short order of a quake especially of this magnitude. I recall from the 94 quake here in LA that we reached over 1000 aftershocks within several days; some of them were nearly as large as the original shake. And there were devastating aftershocks as long after that quake as 6 months.

If you think about it, if there were no aftershocks I'd be rather concerned...a massive amount of earth just shifted; it will continue to resettle for quite some time...and if it doesn't, then there is additional pressure which needs to be considered.

So yes, that many aftershocks (either 50, or 29) is really rather normal.
