Just from looking at the area from any decent satellite view, you can see all of the deposits that you mention. Salton appears to have had quite a violent volcanic past as well. In looking at the very fertile area to it's South, I would also surmise that quite a large amount of fertile volcanic debris has contributed to the current landscape as well.

Funny you should mention that:

This cluster of seven geothermal plants is the largest of three major geothermal energy production sites in the Imperial Valley. A network of deep wells drilled in the geothermal field allow water, heated by the earth's mantle, to come to the surface and to power electrical generators. Owned by the CalEnergy Company, the electricity is sold to the local power utility and put on the grid. The seven plants in this field produce enough electricity to power over 100,000 homes.

"We show that the earthquake rate in the Salton Sea tracks a combination of the volume of fluid removed from the ground for power generation and the volume of wastewater injected," said Emily Brodsky, a geophysicist at the University of California, Santa Cruz, and lead author of the study, published online in Science on July 11.

I'm noticing a "boy who cried wolf" mentality taking hold around here. You could discover a life ending asteroid on a collision course withEarth and plenty of proof to back it up and folks would still call you a paranoid fear mongerer.

I've been noticing it for a while.

Someone says "earthquake" and it's the end of the world.
Someone says "Democrat" and it's the end of the world.
Someone says "Republican" ... "debt" ... "austerity" ... "aliens" ....

It's one thing to 'suggest' a connection between disparate things, but it's saddening to see people jump on the bandwagon blindly, without a shred of critical thought given. And even worse: to see people jump on the wagon citing entirely DIFFERENT conditions / scenarios.

I remember mantras given in the 70's and 80's stating "question authority", and see those same people blindly drinking whatever flavor Kool-Aid was offered.

So, as to not get too far off topic- yes, this was a comparatively large earthquake and there was no tsunami. You'd think that with the closest coastlines being with 300 miles to the northwest and within 50 miles east or west, were there a tsunami worth noting, it would have been noted.

reply to post by abecedarian

I can't recall a noteworthy tsunami ever being generated from this area even with it's history of sizable quakes. I wish I was more learned on the subject, then I could say with authority that it's because most of the large tsunami-generators are subduction and not strike-slip areas.

On a side note - c'mon guys, you have to admit that we've all been "schooled" or "served" or whatever it is that a 15 year-old know-it-all who has just learned all the catch phrases of the most experienced trolls would call it. It's all there... The alternating CAPS, 'controls ATS', 'warrior', scary avatar - We've been "drive-byed" by a person with extremely low self-esteem who's probably off checking to see if any biceps or facial hair have appeared yet. It's OK Jimmy, maybe when you grow up you could be a police officer...

Reading some news this morning and I see that a 2nd Oarfish has washed ashore in SoCal. When the first one did, it was described as 'A discovery of a lifetime'. My first thought was that something in the deep is killing them, such as gasses being released.
Article

In reading the comments section, I see this remark:

Good news? not at all, according to Japanese mythology seeing these fish wash up is a portent of a coming earthquake and in fact dozens washed up in Japan in the months preceding the great quake a couple years ago. This "myth" may very well be based on science, these creatures live at great depths and may be sensitive or even damaged by ultrasonic noise from tectonic plates moving against each other before a quake.

OH No... Did I just doom porn???

I saw that article too and thought about posting about it.

If the myth has any veracity, I might be worried. The first oarfish was found off of Catalina, 22 miles south-southwest of Los Angeles, and the second off Oceanside, about 45 miles east-southeast of Catalina- almost forming a right angle- LA to Catalina to Oceanside.

The San Andreas fault is well inland. The closest semi-major fault to the ocean is the Elsinore Fault Zone, which forms the mountainous region along the coast, with the San Jacinto between Elsinore and San Andreas. There are also recently discovered faults off-shore as well, not far from San Onofre nuclear power plant.

The implications are tenuous at best, but being that I live on the east side of the Elsinore fault, as I said I might be worried.

2.6 followed by 3.6 just a bit ago, maybe 30-40 miles south of the US-Mexico border, along the same fault:

Was looking at a map of faults in that area, are you talking about the Newport/Inglewood/Rose Canyon Fault Zone?

The fear mongering doom porn is deplorable.. It's a damn earthquake in the middle of the ocean, big deal..
Let's stop with the over dramatic overtone and star farming.

The only stars I see being farmed are ones in response to your
over reaction.

People in this forums have been discussing
above 6+ EQ's for years without deplorable doom being the focus.
That's what the forum is for.

I believe so, though Rose Canyon, from what I can tell, is an extension of the Newport-Inglewood fault.

en.wikipedia.org...

... About 30 km (19 mi) in length, it starts in the Mission Valley area and heads, past Mt. Soledad and La Jolla, into the Pacific ocean, where it joins other faults, such as the Oceanside Fault. Not much is known about this fault at present, though its slip-rate is thought to be 1.1 mm/year. The Rose Canyon Fault has recently garnered more attention because it runs through such highly populated areas, but is not thought to be much of a threat. However, some geophysicists, such as San Diego local Jeff Babcock, have hypothesized that a concentrated earthquake involving the Rose Canyon, Oceanside, and Newport-Inglewood faults could result in an earthquake up to magnitude 7.6 on the moment magnitude scale.

en.wikipedia.org...

The Newport-Inglewood Fault is a right-lateral fault in Southern California. The fault extends for 75 kilometers (47 mi) from Culver City southeast to Newport Beach at which point it runs out into the Pacific Ocean. The fault can be seen on the Earth's surface as line of hills extending from Signal Hill to Culver City. The fault has a slip rate of approximately 0.6 millimeter/year (0.02 in/year) and is predicted to be capable of a 6.0–7.4 magnitude earthquake on the moment magnitude scale.

Seems most of the recent quakes on that fault have been at the northern end of it. That either zone is capable of > 7 makes me shake (pun intended).

Elsinore fault itself is 'theorized' to be capable of 6-7.5.
The numerous hot springs in the area add a little bit of concern as well... 'cause what makes hot water come up from the ground?

Uh-huh...
I don't live far from the World's Largest Mineral Hot Springs. I personally think it's tied into Yellowstone somehow, there are a few theories floating around out there about a much larger rift than is currently accepted.


Back on topic somewhat, I've seen videos of the Salton Buttes area and that's another one that amazes me. Would love to see it in person.

Thanks for the info. ...Happens that the sun just released its strongest solar flare in months and caused a minor geomagnetic storm here on earth. imho, there could be an association. Also, seems the sun's activity is increasing and we may see more geomagnetic storms.

Strongest solar flare in months unleashed by sun

An M2.8 class flare erupts from Sunspot AR1865 at 9:48 p.m. EDT on Tuesday in this still image taken from a video by NASA's Solar Dynamics Observatory.

The strongest solar flare in nearly two months erupted from the sun Tuesday, causing a minor geomagnetic storm as charged particles from the sun passed by the planet.

...Geomagnetic storms occur when solar particles interact with Earth's magnetic field. Powerful solar flares aimed directly at Earth can sometimes cause significant disruptions to satellites in space, and can knock out power grids and communications infrastructure on the ground.

edit on 20-10-2013 by sageturkey because: Add

I think the buttes are remnants of history. Not much chance they'll do much, and the Colorado River has done its thing. There are remnants of volcanos from Mexico, up through Arizona, Nevada and the like.

I think there's a subtle connection to Yellowstone, almost as if rock couldn't be extruded in the 'California' area of the North America plate, somehow it was diverted a bit and "poof" up there.

reply to post by abecedarian


Gotcha.
I was actually referring to a possible connection between Thermopolis and Yellowstone. As for Salton? It's still considered active though, isn't it?

Earthquake swarms and a region-wide rotten egg smell recently reminded Southern California residents they live next to an active volcano field, tiny though it may be.

man, this is ATS. if you take away all the doom porn this site would not exist. also, the OP wasn't very doomy anyway. it was your basic "hey, this was a significant quake in an area that might be of concern". the "stop fear mongering!" posts get old. we get it. nothing bothers you and there is never really anything to be concerned about.

Yep - I never give too much credence to those who don't know the difference between 'to' 'too' and 'two' besides.
Just a peeve of mine I suppose...

Nothing to big a deal, pretty far from the california line and in the middle of the ocean..

And yeah, I'd hardly classify the Gulf of California which on average is less than 100 miles across as "The middle of the ocean" but I digress... Everyone's entitled to their own opinion and we're entitled to respond to their unwarranted attacks right?

One thing that I have noticed when watching this area is that (at least from my perception not backed by any data) when a large EQ does occur there, at least a few more big ones follow. Usually separated by a timespan of 12-24 hours.

edit on 19-10-2013 by sageturkey because: Forgot not to feed the trolls...

Not to be too critical, but aren't your punctuation (absence of commas) and sentence structure (use of 'besides') errors akin to his/her grammatical errors?

It doesn't bother me, just wanted to know why one instance peeves you, while the other obviously does not.


As far as the quake reporting goes...

EQ's and the post EQ consequences can be catstrophic and even fatal. I feel that there are too many times when people are mis-informed or the full magnitude of the potential risk is under-estimated. Personally, those reasons are why I would rather have someone's fear mongering remark alert me to the potential danger, rather than someone down-playing the magnitude and enabling the means for a false sense of security.

edit on 20-10-2013 by sageturkey because: Correction

I haven't fully educated myself about volcanism in the area, as if that were even possible; more of a casual glint of knowledge. There is evidence of relatively recent lava flow all across the southwest, the areas I mentioned earlier. These buttes may not "erupt" but would likely emit lava as surface flows.

reply to post by esteay812


That's a good question! One too which I don't really have a valid answer...
I often use double commas and start sentences in my posts with the word 'and' as well, knowing that it's incorrect grammar. I've never been one two be a grammar cop on ATS, you won't find a single post other than this one where I have brought up another member's spelling or grammar. Many people even spell it grammer while complaining about it...
I guess that it (in my mind) comes down too basics. While sentence structure can be something that is difficult too master, the use of to too and two seems very basic too me.
I'm trying two think of another example of something that (in my mind) is very basic stuff. There are only to of them (I just can't resist having some fun with it...) that for some reason get too me.
ETA: Oh wait, now I remember! There Their and They're...
/End ETA

Maybe I was angry with the way we were chastised for discussing this, saw a weak spot and took advantage of it as a means of rebuttal. It's tough two psychoanalyze myself...
Nonetheless, I gave you a star just for playing and for giving me a chance two use the words incorrectly as many times as possible.

Back on topic, nothing new too report regarding the Gulf of California.
