Quake Watch 2013

reply to post by PuterMan


Hey PM, I made a post about that little line of quakes last week. Here is a link.
It is at Sutter Buttes, a 1.4 million year old volcano, that leaks methane.

Thanks PM, that's all I could find that even remotely resembled what Daughter posted.
Do you still keep sound files cause I would love to hear what that last graphic you posted sounded like?

That seems to be about 38 miles from the Folsom dam.

 

Anyone know what this area is? (Click for slightly bigger image)

edit on 6/2/2013 by PuterMan because: (no reason given)

This seems to explain that area

According to Wiki
:Sutter County is home to the Sutter Buttes, known as the "World's Smallest Mountain Range." This volcanic formation provides relief to the otherwise seemingly flat Sacramento Valley. For further information about the Sutter Buttes go to [1]

en.wikipedia.org...
Bordered by the Sacramento River on the west and the Feather River on the east, Sutter County has 240 miles (390 km) of levees. The Sutter Bypass, which diverts flood waters from the Sacramento River, cuts through the heart of Sutter County

So you did. I remember now.

Must be old age creeping up on me.

Must be old age creeping up on me.

I envy people who have old age creeping up on them. It ran me over like a Mac truck and backed up to do it again a couple of years ago.

If everyone who repeated a post already made in a thread this size were banned there would be nobody left here.

Muzzy or Puterman,

I hope I'm not repeating something you may have already posted. I am curious about the whole scene since dec 2004 starting with Banda Aceh. Since that time, there's been a string of 8's me thinks. April 1 2007 as well, and maybe the two eight's last year are all part of Austrailia's movement. Yes, volcanoes. I can't see how all the activity since 2004 wouldn't cause moving magma.

I wonder how this last ten years compares to the ten years previous. Is the last decade normal when compare to other decades. And I'm refering specifically to the plate from the west off Sumatra over to the east where this last bit happened. I'm sure Muzzy will want to say hey, include NZealand in that mix. Maybe. What do I know?

Oh, got some editting time. I just noticed that just three days prior to the Dec 26, 2004 , 9.1M off Sumatra, on Dec.23, there was an 8.1M on the opposite side of Australia, southwest of New Zealand. Hmm. Then three months later, 8.6M off Sumatra.

2007 had a couple big ones near Sumatra.
What volcanoes are near Sumatra? Krakatoa. Toba. so on and so on.
Can you say, big eruptions over due?

SANVU 0000hrs to 1000hrs 06 Feb 2013 (2+ Mb download)

This is a FLAC file playable in WinAmp amongst others and is at 1000 times speed because @580km this is just about a teleseism and at lesser speeds it would take too long to play 10 hours and you would not hear most of it.

BTW if I post a spectrogram I always have a sound file available.

reply to post by ericblair4891


I am off to bed and Muzzy is just about arising so I will leave that one to him, unless it is not done tomorrow when I may have a look at it.

@HappyCat - did you get that truck's license plate? You should report it for reckless enagement.

reply to post by PuterMan


You're the (Puter) Man! Thanks, that was pretty amazing. I downloaded winamp a long time ago just to listen to your files.

Also think in this 70 days we will have strong seizmic activity worldwide and M 8.0 + somewhere at "Ring of Fire" ..

Location for possible EQ of M 5.5 + ..

Also think EQ will very probably come somewhere here on this image, around town Barga..

Also have possibility that EQ will appear in next 2-3 days at this location ..

Dead On.... amazing

btw- about the 5.5: From what I've experienced .... a 5.3... they aren't so bad. A lot of shaking, but no visible damage. But I am mostly in an area that has mostly poured cement, or block-built cement houses. Maybe that makes a difference. There were no warning pre-shocks. It lasted probably under 10 seconds.

Like I mentioned, the Duration of the quake I believe is of paramount importance... something that seems to be overlooked most times. A 5.3 for 1 second, or a 5.3 for 10-20 seconds can make all the difference(?)

I have no idea why, but somehow I have the feeling, that it is not over yet at the solomons. I would wait a few more days...

edit: btw. it seemed a bit too quiet in Japan today.

1- 8....1-7.....4- 6's.....and 64 5's in a 24 hour period

All I can say is WOW!!

earthquake.usgs.gov...

Look at the change in the depth of the last 4-5 aftershocks.

earthquake.usgs.gov...

I wonder if this is anything to worry about.


Never mind...... I now see that there are quite a few more in that range

I too noticed the depth change. I don't think it means anything if only because I have the feeling that when the rush was on many of those were ??? depths as they are mostly the default depth of 10km. I don't know if they have stations closer than SANVU and HNR but if not there could have been much 'noise' on such teleseismic distances. (Listen to the sounds)

ETA: As someone once said a picture speaks 1000 words......

Magnitude 8.0 Solomon Islands (No stupids - Santa Cruz Islands)



Some details from IRIS if you are interested from Recent Earthquake Teachable Moments which have some data in PDF and PPT form and some TA station videos of the seismic waves passing through.

Puterman, I think your hunch concerning the 10 km depths being reworked as the seismologists get caught up is right on the money.

Remember back on the 11 and 12 April 2012, after the (2) Sumatra mag 8's, how there seemed to be an outbreak of triggered seismicity around the globe?

Magnitude 6.9 GULF OF CALIFORNIA April 12, 2012
Magnitude 6.5 MICHOACAN, MEXICO April 11, 2012
Magnitude 5.9 OFF THE COAST OF OREGON April 11, 2012

Source

We haven't seen anything similar following the Solomon Islands unleashing. In fact, the only Mag 5.0+ eq since the Mag 8.0 that isn't related to Indo-Australian plate movement is this 5.0 on the northern Mid-Atlantic Ridge.
It's as if the rest of the world has taken a nap. Just an observation...

One last thing. Did anyone notice the fault mechanism ascribed to the Mag 7.0 01:54:15 UTC aftershock? (It's the big yellow dot just north of Lata)
Strike-slip rupture at only 9.8 km depth. Whereas, the mainshock was a really shallow-dipping thrust fault with a hypocenter nearly 3 times as deep.

I can't fathom the contorted stresses necessary to cause all these different mechanisms and depths; those rocks are tortured.

ETA: Thanks for linking that PDF, Puterman.

edit on 6-2-2013 by aLLeKs because: (no reason given)

All:

I don't know if I'm fabricating a memory trace or recalling one.

IIRC, there was some sort of prediction or prophecy sometime in the last 5-10 years that when there was an extra large intensity quake in the Solomon Islands area, NOT TOO LONG AFTERWARDS there would be a very devastating quake either in Japan or the Left Coast of the USA.

Does anyone else recall something similar?

If I had to guess if this would be possible, I would say yes.... it seems really really quiet in Japan, but since I am only watching USGS, just because I have no time to watch other sites too, I have no clue if this is true.

But USGS tells me, that there was only one quake (bigger 2.5) in Japan within the last two days... this seems scary, but I can be wrong

edit: seems like jma has some quakes. still very quiet.

reply to post by aLLeKs

typical, I track Japan for a month and no one seems interested so I stop bothering and then you go ask that question

from NIED (most recent data 10 minutes ago)
