however on that page they quote their own reading of 6.5Mw


No, the GFZ value is the mb value like the EMSC was 6.4 mb. GFZ have 6.2 Mw in the tensor calc. I linked it above. That is consistent with what you calculated.

which is just off the coast there, I guess it's fair enough for them to say that's where it is


You missed my point which was almost exactly that . "near" can be on land or at sea. It is ambiguous. On land it should be related to the nearest town and at sea it should be "offshore". I would accept "On the coast of" as basically on the seashore. I am just being picky
.

As far as LDEO goes i will let John Vidale speak for the site


Personally, I always use the Lamont number, if it is available, as Goran has included lots of nice corrections and carefully calibrated it - he's an artist. But for fast, good numbers, the USGS page is great, plus I can call them with questions, should they arise.

I don't know why all the depths are at 33km. Perhaps John V can spread some light on that if he spots this on his next visit.

This one in Chile seems a little slow on the aftershocks.

It was on the deep side and they tend not to produce so many aftershocks.

Not sure if the area does anyway.

Whoa, the back of our house shook tonight.
It was like someone opened & closed the back door really hard.
Hubby & I were sitting on the couch & looked at each other, thinking it was one of the kids stopping by.
But after a few seconds no one had walked into the room!

I went & looked, nobody around... no car in the driveway... nothing.
Hubby went & stood outside for a little while & said he heard a boom, kind of like a car door slamming up in the woods.
But there isn't a road into the woods & no sound of a car motor!
It was very quiet, there's been a light rain most of the day, hardly any traffic down on the highway even.
We live in a quiet area, not that close to town, no background noises!

We felt the 5.8 in Virginia, here in north central PA. Also heard the 'Seneca Guns' during Chile's big one.
And thought we did again when Japan had that last 6.3. So I've been checking USGS but nothing yet.
Unless a close, small one gets listed on folkworm later! Just thought I'd put it out there in case something is starting to move!!!

Earthquake movies, 1D and 3D synthetic seismograms for seismologists

Global ShakeMovie is Princeton University's Near Real Time Global Seismicity Portal (Tromp et al. 2010). It has been designed to present seismologists with near real time 1D and 3D synthetic seismograms for recent earthquakes. These synthetics are the results of simulations carried out on a large computer cluster. 1D synthetic seismograms are calculated based upon normal mode summation. Movies and 3D synthetic seismograms are calculated based upon the software package SPECFEM3D_GLOBE.
Synthetics (3D and 1D) will be available for download 7.5-11 hours (M=7.5) after receipt of notification from the Global CMT Project.

Just had a good old rumbler pass thru Christchurch!

Will report back once I can get details.

Damn, it was a 4.36 which is the largest we've had here for sometime!

10 and 33 km are default depths in cases in which the precise depth is difficult to determine. I think they are starting guesses for depths, and then wind up as the final estimate if there are no constraints, but I am not sure. 33 is a bit deceptive, as one might guess 30 or 40 would be more likely numbers for a guess.

Thanks John. Yes I realise it is a default depth but it does seem a little strange that it is always 33km for every quake as long as I have been looking at that list.

Whilst replying to you I have taken a notion to ask Goran in person so I will post his reply here if I get one.

I have just uploaded the whole of 2011 earthquakes in Iceland month by month in case anyone is slightly interested. Obviously I have the individual files as well if required.

I shall up load Oct - Dec 2010 shortly and then Jan to Apr 2012.

33 is a great number. It's basically 1/3 . You are a third the way toward a hundred. When you divide 100 by 3 you get

33.3333333333333333333333333333333333333333333333333333333333333333333333333...

33 1/3 approx. 1/3+1/3+1/3= 1

but

33.3... + 33.3... + 33.3... = 99.999999999.... that little bit left over...

god

No, the 0.1 %


My concern about 33 is that the value is not an integral part of the calculations as may introduce erroneous values. The magnitude of a quake can change quite a bit if the lat/lon/depth change.

The little bit left over isn't 0.1%. it's 0.000000000000..... at some point just before end of everything ... 0001.
This is what I get when I start thinking of the trinity. Solid, liquid, gas. But then there's plasma and dark matter and equation fails. We in Canada are very smart and have decided to kill the penny. We are a practical people and the cent made no sense. So now, there's a bunch of clerks with markers crossing out the 19.99 price tag and putting down 19.95. The price of copper is going to rise further still. The metal is too valuable to be wasting on pennies. We could be selling the shiny metal to the Chinese instead. Well, at least we're not having people take our manhole covers and shipping them to Central Asia. The 33 marker is I guess, the best guess the can guess. The had to pick something to divide up the depth guess. They could have use 25. I don't know. But isn't eveerything an approximate. Because 1 doesn't equal 1

Thank you for the Popo siesmo. Since I'm unfamiliar with it I'm not sure about what I'm seeing. Do you have information about the site? Is it borehole? No? Because I see something on todays', about midnight there's something going on for a few hours. Wind? There was a similiar signature yesterday but not as long. I know sometimes it's windier at night in some places but not sure what it is..

And worldwide it's still kinda quiet. A 6M along the spine of South America is a baby quake there. I ...
Checked. The quake cut power lines for a short while. A few walls damaged and broken windows. I love these people. They rushed out into the streets when the shaking started. And as soon as it stopped, they went back in. They live with earthquakes like we live with thunder storms. It's exciting while it's happening, but they'll probably forget about it later today when the power comes back on. But if you look at Azerbaijan, I give up, I swear the other day I read there was one death, can't find confirmation of that, but there was lots of houses destroyed or damaged. Get this, I read there were 15 injuries. But they were from the "unrest" afterward. What?

en.trend.az...

Anyway, my point was that the Azerbaijanis are nowhere close to the preparedness of the South Americans.

There is a region that's bucking quiet trend at the moment. Asia.

Had to add. Puterman, two of your Reykjanes Ridge quakes popped up and I tried to check weather, it appears a low pressure system crossed the North Atlantic recently. But I can't be positive.

I guess that joke backfired then!!


Thank you for the Popo siesmo. Since I'm unfamiliar with it I'm not sure about what I'm seeing


The Popo seismo is showing tremor.



Unfortunately the time of the black marks is when my computer was off for the night so I don't have the image that corresponds, except the last 12 minutes and it definitely was more active but then died back down again. I have just over 3,550 images with one being added every minute but most of them you can see nothing.

Certainly did. A big depression passed over Iceland.




or another view of it



Or I could show you one or two satellite maps as I collect Infra-Red, Visible and Mean Precipitation Estimate maps as well. I have several years of data and one day i will get round to matching it all up!!!! Oh jetstream maps for 12 years as well and Icelandic quakes back to 1995.

So much to do and so little time left!

20:43 BST (19:43 UTC) Looks as if a bit of tremor is starting again. Might be worth watching.

I think you are confusing GFZ with DGF the Chilean site. www.sismologia.cl...
my mistake, I put GDF in the post instead of DGF

too many G's And F's in one post
