they predict upcoming earthquakes also?????
www.earthquakesummary.info...
I'm checking this out!!
Whoa, how long have they been able to do this?
That earthquake summary site is a joke
Why not just say "there will be a 3.5 - 4.5 somewhere in the World tommorrow" same result
And the article about Queensland triggering Christchurch is ludicrous
There have been over 5000 aftershocks in Christchurch, why should one in particular be caused by something that has happened once in 300 years (on another Tectonic Plate to boot)
www.earthquakesummary.info...
also they hven't done much research about the Kermadec quake the other day
Um, what about these ones South of the Kermadecs ON the Kermadec Ridge or Havre Trough
2000/05/08 M7.2 and 2000/08/15 M7.6
1997/05/03 M7.1 and 1997/05/25 M7.9
1996/11/05 M 7.3
1995/06/03 M6.7
1992/08/08 M7.1
1990/03/21 M7.1 and 1990/05/20 M6.8
Mag 5+ NZ quakes
and the quake they seem to be refering to in 1985 must be the 1985/09/26 M7.0, which wasn't even ON the Kermadec Ridge or in the Trench but east of the Trench ON the Pacific Plate
Pffffff

A highly unusual earthquake of M 5.2-5.3 in Queensland, Australia today was followed by an aftershock of M 4.7 about an hour and a half later and by a strongly felt, dynamically triggered earthquake in Christchurch, New Zealand 30 degrees to the southeast 18 minutes later.

It is the strongest earthquake to hit this region south of the Kermadec Islands in more than 20 years. The last such earthquake in the region occurred about a week after the great Mexico City earthquake of September, 1985 and was followed by three subsequent quakes of similar size over the next year.

Well said muzzy and thanks, you saved me the bother!
Why is it that there are so many of these predictions sites out there that are incapable of predicting anything yet still continue to try - as far as I can see purely to generate site traffic for many of them as they are filled with ads. I know this one is not, but many are.
This reminds me of the one about California which predicts ranges like 3.5 to 5.2 - a ludicrously wide spread.
:shk:

I posted this one because USGS isn't showing it and it is the most predominant trace on SNZO at the moment

haven't had an Antarctic Plate quake for a while
edit on 20-4-2011 by muzzy because: I took some screenshots
and shows quite well on Raoul Is. and Palmer Station too
aslwww.cr.usgs.gov...
I can't understand why its not on the usgs list
I think its important, what with the North and South Mid Atlantic Ridge quakes yesterday, also areas of spreading, a phase of expansion perhaps?
edit on 20-4-2011 by muzzy because: (no reason given)
Muzzy, your view of Antarctica triggered a question.
Possible Antarctica is causing quakes because of melting of ice;
great reduction in weight - now the whole plate is mobilizing.
It is a VERY big area, but it is also a very big plate. Yes, I know this is very far fetched;
but it might shed some light on the recent series of quakes also South from South Africa;
an area and country which does not know earthquakes.

Because Potsdam have it as 4.7 therefore USGS will have it as 4.3 and that is below 4.5 and no one felt it so it does not get listed. EMSC don't have it either as they are clones of USGS for the most part.

wasnt there a mass fish die off in California just before the japan quake?

It says a 5.8 hit off the coast of Honshu, JPN, 50 minutes ago. Aftershocks--if that's what these are--continue. Is it normal for such a large number
of aftershocks to hit a region over such a short period of time after a "big one?" We are talking hundreds of 5+ magnitude here. . .

Aftershocks can continue for months - we
just don't want the magnitude to increase.
Good observation on your part - I had not
noticed the quakes today and I like to keep
track with larger and more frequent ones.

2 strong quakes close together - is this a good thing
or not? Hope all is well there.

IMHO, If I lived in Japan right now, with just these 2 quakes on their own, I would be heading inland to high ground - Just as fast as I could get there!

Thats possible, but there hasn't been any increase that I've seen.
The ice is melting on the fringes, offshore, so there would be no "spring-back" of the land as such.
But its an interesting subject, as the sheet ice melts there is less resistance to the Glaciers, so they will also melt faster, and there should be some movement of the ground there.
I read somewhere about some Glacial quakes in Antarctica that were the equivalent of Mag 7's
Antarctica is the big unknown, I would have thought there would be more earthquakes there, especially with Mt. Erubus being an active volcano. I look in here occassionally but there hasn't been anything unusual since I first looked.
Antarctica is the only Tectonic Plate that is not subducted or does not subduct another.
This is a pretty interesting site, covers some stuff on Antarctica www.iceagenow.com...

Because of the size of the mainshock yes these aftershock sizes are normal. And within aftershock sequences you can get periods of quiet, and then a cluster of large shocks. Also, and this is from experience here with our 7.1 and 6.3 earthquakes in last 7 months, you sometimes get a new raft of larger ones quite some time after the mainshock. Five weeks after the 7.1 and after a period of quietening (although now over 5,000 aftershocks here) we suddenly had a few 5's...
Rule of thumb for aftershocks says a quake of 1mag below the mainshock is usually expected, could be weeks or months after mainshock. So Japan could well still see a mag 8.
