Just back from dinner hence slow reply...

Thank you for the excellent data summary. So today's quake in Bolivia is the biggest very deep quake in that region (radius 200 km) in quite some years, then? And quakes that deep are also rather uncommon there.

Hmmm...

No wonder it was bothering me. Okay, some might wonder but never mind about that right now...

Now thinking out loud: were there any large events down on the relatively nearby coastal subduction zone regions within (say) a few days to maybe a couple of weeks of those deep quakes?

That is one big quake. And the biggest sub-300km quake ever recorded.

People, this really bothers me a lot.


To explain, I was scratching my . because I thought that mention of Bolivia on the "Experiment" thread was not my first. Felt sure I'd already at least mentioned my concerns.

Turns out I did. I must be getting old... The first mention was last Thursday (Nov 17) in this Quakewatch thread! The post is here but it doesn't surprise me that it went unnoticed as it was just a note I dropped in as an edit, because it suddenly came to me that I ought to mention it. All I said then was:


EDIT: Right now I'm concerned about Bolivia. Just saying. (Gut feeling. That's all.)

edit on 17/11/11 by JustMike because: Fixed link and mentioned Bolivia


The "Experiment" thread post was just to log it more-or-less officially as an area of concern.

But like I said it's been bugging me a lot, this "Bolivia" thing. I wrote a U2U to a member earlier today about it (at 09:23 UTC), in fact. I actually began thinking that either I was wrong about "Bolivia" and had misread the word, or else it was something less important and the main event would be elsewhere. Thought of the US and asked other member for opinions on US places that might sound like Bolivia.

Now, though, this event has got me worried. I don't like this at all.

Hoping that nothing bigger comes from it.

Mike

Mm, you got that the wrong way round!


It is also the largest earthquake ever recorded with a focal depth greater than 300 km


en.wikipedia.org...

Generally the mega-quakes are in the shallow earthquake region i.e. sub 70km.

Sorry, sometimes I know exactly what I mean but I make a mess of letting others get the same message. Especially when I'm pretty shaken. Like now.

What I meant was that in repect of the historical list of larger, very deep quakes, were there major events in the stated subduction regions in the days to couple of weeks following them? (Not necessarily the very rare mag 8 or bigger, but say in the mag 7 range.)

Sorry about putting it so poorly. I feel really stupid.

By sub-300 km I mean below 300 km. Meaning deeper than 300 km.

Yes I can see now that I messed up the term but my point was how very deep that 8.2 was. It's almost incredible to have a big quake that deep.

But I know I'm making little sense and I'm sorry. I am not feeling good right now and my . hurts. Not joiking. My apologies, Puterman. Please excuse me.

What is this?


It is nothing. That site is very similar to the EMSC site and is very error prone, as we discussed before.

You can pretty much guarantee that the data is an erroneous pick of the Bolivia quake.

As Puterman says, it's likely just a bad pick. And that data is NFP, anyway, as the site says. Only useful for experts and more likely only harmful for those who aren't. Which is why we rarely refer to it as we don't want to confuse people.

I have to sign out. Don't want to make any more half-incomprehensible statements and annoy my friends (which is all of you).

Goodnight all. Stay safe and peaceful.

West, guess you missed diamond's post here:
www.abovetopsecret.com...

He did follow up, and claimed he was fast...lol. Truth is, I saw the quake in GEE first, and saw the report literally the second it came up on USGS, cause I was waiting on it. BUT due to being post banned at the time, could not report back. I get myself into trouble all too often on ATS in other forums, not here. This thread has become a model of ATS cooperation and friendliness (for the most part). I can't remember the last time a moderator was ever even in here.

As to the 3.0 quake in Yellowstone, yeah it was just inside the western caldera rim:
www.seis.utah.edu...

But in a spot also prone to a lot of little quakes, so seems to be nothing unusual:
neic.usgs.gov...

In fact, I would say it is the typical YS sporadic seismicity that we can expect from the park.

TextEarthquakes associated with a collision boundary define shallow, broad zones of seismic activity that form in complex fault systems along the suture zone. Earthquake patterns in subduction zones are more complex. As the oceanic crust begins to descend, it begins to break into blocks because of tension stress. Shallow earthquakes in the upper part of the subduction zone are a result of shallow-angle thrust faults, in which slices of plates slide like cards in a deck that is being shuffled. Earthquakes also periodically occur as the plate continues to subduct up to a depth of about 670 kilometers (400 miles). First-motion studies of these earthquakes suggest they result from both compressional and tensional forces on the subducting plate.

PM and muzzy, you notice the waffling going on with this Bolivia quake? I mean jeez, comes up as a 6.8, then down to 6.2, and now at 6.6. And the depths all changed too, way beyond the uncertainty +/- figure. Phase data has La Paz as closest station, and that's like over 330 km away. I saw the thing come in on GEE (but was post banned so couldn't report). My initial guess was 5.8 to 6.2 range, but I was having a rough time too trying to pinpoint location. Bolivia could probably use a few seismos.

I don't know if anyone happened to notice the EMSC version but they came in at 6.9, went down to 6.7 and then 6.6 and stuck there.



USGS had 6.7 to start. This was under a different ID



They changed the ID and brought it down to 6.2 and I said to my DB "I wonder if EMSC will capitulate and bring it down" but I did not have time to examine the phase data. I was quite surprised when EMSC "won".
