apologies to 'Cherryontop', for it was your goodself that I hoped to forward the BBC 'The Core' info to. Thank you for info returned, all covers the said uk programme and indeed adds more. Trying hard to learn this end of the line and will therefore remain a deeply interested student. Thank's once again to Puterman plus great detail suppliers. This - in my mind - is the Best site yet.

People on another website are talking about an earthquake in Colorado that posted, but then disappeared this morning.

What do you make of this Puterman.

That's nearly 400 miles deep. Usually when they're that deep, they are usually the result of plate boundaries being subducted into the Earth’s mantle. No one likely felt it, either.

Still, interesting. Quite an active Earth the 10 days or so.

Don't be so sure about that. Unless you're there and experiencing it yourself, it's not wise to make assumptions that "no one likely felt it".



A magnitude-6.4 earthquake has struck north-central Argentina, shaking things up enough to make people evacuate some buildings in the capital hundreds of miles (kilometers) away.

The U.S. Geological Service says the quake's epicenter was 80 miles (130 kilometers) southeast of Santiago del Estero, a provincial capital of 250,000 people and the 12th-largest city in Argentina.

It was centered deep underground, nearly 400 miles (600 kilometers) below the surface, where quakes generally cause less damage.

The shaking prompted people to spill out of the San Isidro courts building in Buenos Aires province Friday morning.

Just a tiny, over simplified observation, from a novice quake watcher...

All of the mainland US quakes that are being discussed here on ATS (VA's 5.8 and the ensuing aftershocks; the Utah quake of today--Antimony, UT; the Trinidad, Colorado quake of earlier in the week--and ensuing small aftershocks; the swarm slightly south of Mammoth Lake--Long Valley Caldra) ALL on the 37th parallel. The Utah quake being just at the 38th latitude line (as well as an odd ball quake in WV, at the 39th latitude line). Visually, looking at the USGS quake map its just like a band across the continental US. And I now quakes happen all over the planet, but recently the map has been a 'connect the dots' line up across the mid US. (Again, just a novice observation).

Don't know if this spoils your band but there was no quake in Utah today.

As I have explained previously this was a computer pick error.

Agreed. However I believe thankfully no great damage or loss of life.

Now here is an interesting seismo of that event - or was it actually TWO events?

LVC.IU.10.BHZ.2011.245

I will copy that and put it here in a moment.


edit on 2/9/2011 by PuterMan because: (no reason given)




Could be one, that is a massive P wave if that is the case considering how far this seismo is from the event both across and down!

Puterman,

questions for you...i live right here in Sta Clarita and felt the 4 pointer. i know aftershocks are normal....BUT we've gotten a whole lot right after the quake. I am new at quake watching, but for an eq that size, any after shocks should be like one or 2 a day right?
what i've seen is multiple aftershocks within the day as if the quake was a 6+

is that normal? am i putting too much into this?

i have a feeling that something else might be brewing....

sorry - my main question is...can you explain to me the whole shallow/deep earthquake thing? i think i got it mixed up by reading on to many threads...

4miles deep is considered shallow? ...if it's shallow..is it magmatic in nature??

Obviously Google Earth is an idiot as it does not know there is a Santa Clarita in California - but there is one in Peru. This is the trouble with Spanish place names!!

Aftershocks can be many or few. Generally you tend to get more from a shallow quake than you do from a deep one. Sorry it took me a while to find out where Sta Clarita is exactly as there are a few 4 pointers in the world. I hope I am correct as locating this in Peru? If so are you really 570 miles from the 4.8? You will have to fill me in a bit more on your location and whether I am even looking in the right area.

Big IF, but IF you are where I think you are then those could be magmatic as you have a bunch of tall smoking mountains around there that are prone to blowing out a few puffs every now and again including Sangay which is erupting I believe.



is that normal? am i putting too much into this?

California - Yes fairly normal. Look at the huge number after Baja. I don't think I would be too concerned about the number of aftershocks in this current (sorry muzzy) swarm. I am sure that berkelygal would be the better person to reassure you on this point - after all, I am nowhere near there!

I guess it might but it does depend where exactly you are!


sorry - my main question is...can you explain to me the whole shallow/deep earthquake thing? i think i got it mixed up by reading on to many threads...

4 miles is shallow, and as I said above could be magmatic depending on where you are and what is happening in the area. Sorry I could not answer better but I do need to confirm your approximate location.

Now I (think I ) know where you are I will take another look.

ETA: I see you figured it out before I hit enter.


I don't know if this video has been posted here on the quakewatch thread yet, but you might find this interesting. It is almost due West of the quakes location...not too far to the beach.

This is from a local news report, not some crackpock.




I would be curious to see some local siesmos, based on what they are saying about the after-shocks. hmmmm (off to look)

Puterman, I think they must have meant Santa Clarita, California. They are just 5 miles from the 4.3 yesterday:

They have a cliff that smokes like that in England. Natural hydrocarbons igniting. In England the area is close by where they pump oil with nodding donkeys.

As far as the quakes go let us know what you find on the seismos. Seems odd to me that those quakes are concentrated in the hills.

Not a lot going on at OSI: OSI.CI..BHZ.2011.245

Well that one (Peru) is still around, but it was the 24th so off the 7 days lists.

quakewatch.wordpress.com...

The USGS page is still good.

Not mistake by the way, these are changes after closer examination BUT and this is my point, they always seem to happen AFTER the 7 days.

Most people look at the 7 days list and don't bother with the 8 - 30 and anyway the 8 - 30 list does not have the mag 6+ quakes nicely marked in red just to make it more difficult to find things.

After 7 days it is passée except to el stupidos like me!





edit on 31/8/2011 by PuterMan because: (no reason given)



Okay....just getting caught up on the quake thread for the past two days. Thanks Puterman for looking closer at the sig out of Mammoth Lakes. Wind and solar interference makes sense. I hadn't thought about the 'desert wind'.


I have to say that the more you report about the changes being made after these quakes drop off the 7 day list, the more I question the reporting integrity of the USGS. I would really like an answer from them. I just don't see how it can be due to the quakes being analyzed further. I mean, some of the bigger ones are reviewed 5 to 7 times on in the first few hours, so why such huge changes made a week out?

Another nail in the coffin is that FACT that your own calculations, and those of other reporting agencies tend to closer resemble the 'final' numbers on the late list, vs the 7 day....which tells me it is more than obvious to others, so I am NOT buying that the USGS just can't figure it out themselves as quickly.

I have asked this question before: WHY????

Really. Why.

have you noticed more of a trend as to which quakes have the biggest mark ups? (Or mark-downs I should say on the 7 day list) Is there a certain area that suffers this more than others? I think THAT would be a good indicator as to what is being covered up (if anything)

I now this is a bunch of work, but I assume you have been keeping track of said changes. How about a map indicating the quakes with the biggest mark ups after the 7 day list? That might paint a picture and make us look a little closer at a specific area.

Ofcourse, it could also be that they are simply inept and make a bunch of mistakes. They are, after all, a government agency.
