Something About the Long Valley Caldera - Harmonic Tremors?

I've discovered an anomoly located within reach of the Long Valley Caldera System that could possibly be a branch from it's Magma Chamber reaching out!

The Long Valley Caldera was produced by a catastrophic eruption about 730,000 years ago, forcing 150 cubic miles (600 cubic km) of rhyolitic magma to the surface. It's location exists in Central California, just East of the Sierra Nevada Mountain Range, and is roughly 17 x 32 km in area, which contains several active volcanic regions:

Mono Lake

Hot Creek Gorge

Mammoth Mountain

Red Craters

The caldera remains thermally active, with many hot springs and fumaroles, and has had significant deformation, seismicity, and other unrest in recent years.

Carbon Dioxide and Helium Discharge from Mammoth Mountain, Long Valley caldera, California

Measurements of the total discharge of carbon dioxide (CO2) gas at the Horseshoe Lake tree kill area range from 50-150 tons per day.

Jees! That's alot of CO2! Take a look at the killtree area...

Over the past 35,000 years, volcanic eruptions in the the Long Valley area has been confined to the Mono-Inyo Craters volcanic chain. About 20 small to moderate eruptions have occurred somewhere along the chain in the last 8,000 years, as shown in diagram above. Some of the eruptions occurred at about the same time and in close proximity. For example, the Inyo eruptions 550 to 600 years and the eruptions from the north end of the Mono Craters about 600 years ago. The intervals between eruptions or eruption clusters ranges from 250 years to 750 years

Recent earthquake flurries have been recorded for the Long Valey Caldera System, as shown below:

While earthquakes like this are commonplace for this region, it's interesting to note that a massive fault system stretches from the Caldera region Northward towards Lake Tahoe, where along that faultline exists the Mono Lake Volcanic region and Inyo Craters region. This is noteworthy in that the viscous magma associated with the region tends to seep through cracks generated by earthquakes in the region. Outside of the recent earthquake flurry associated with the Main Caldera system, another more frequent earthquake flurry has been rapidly generating shakers, in a Place along this faultline known as Markleeville:

What exactly are these tremors? Could they be heralding in a possible newly formed volcanic system related to Long Valey? After all, Long Valley has been shaking right along with this location as well!
Something to watch...

What's Going on at Long Valley?

Volcano watch 2010

Quake Watch 2010, page 218

lol, nobody considers this alarming? Remember folks, We're talking about a system of intense volcanic origin... one comparable to the likes of YELLOWSTONE, and LAKE TOBA.

producing a vei 8 eruption that blew over 600 km of volcanic material into the sky, and who's ash cloud covered half of the mainland of the United States is pretty alarming imho...

I'll post more info as soon as it makes itself available. The Markleeville tremor flurry happened yesterday... that's alot of tremors for one day !!

Well i found that to be very interesting, ive got a feeling this isnt getting ignored. The ATSers who are more likely to be in the know are probably giving this a good once over as i type, expect this thread to get very busy as they start to delve into it.

all tho we do appreciate the work that went into this thread , only one thread is needed and that is the whats going on at long valley caldera thread .

You have done a great job with the pictures a star for you for that. I am i agreement with AA in that we should keep it on the existing thread - otherwise thigs get all jumbled and people have to bounce back an forth from different threads on the same subject and scroll multipal pages when they are like - i know I read that somewhere read that somewhere - but where. In my opinion anyway.

I'm glad you appreciate my efforts, but unfortunately I'm afraid that thread's author doesn't have copyright deeds to Long Valley, or reports on topics related to it. This thread is about a possible connection with a weak fault system in Eastern California and it's relation to Long Valley - not the Caldera - which If you'll notive has become a system of volcanic events that have spread away from the main caldera system, to form other systems such as mono lake and inyo craters... possibly even Lake Tahoe, which is about as big imho as long valley itself...

That's correct, I'm hypothesizing that Lake Tahoe - a lake similar in design to Lake Toba and that has a depth only rivaled by a volcanic lake known as Crater Lake, Oregon here in North America... could possibly be an ancient caldera itself...

[atsimg]http://files.abovetopsecret.com/images/member/a20e0fef6146.jpg[/atsimg]

Is Lake Tahoe volcanic? If possible, is it part of a larger caldera System, which includes Long Valley?

Wizard Island, Emerald Bay:

[atsimg]http://files.abovetopsecret.com/images/member/ce97068cc682.jpg[/atsimg]

Emerald Bay is part of Lake Tahoe. Could it be an additional Caldera, with wizard island being a child cone to the Emerald Bay caldera?



Suddely, the possibilities are there. The earthquake flurries at Markleesville then, now, contains possibility...

Perhaps the author of 'What's Going on at Long Valley' therefore should feel honored to be included in this theisis, as it provides info supporting it.

Long Valley Caldera and Mono-Inyo Craters Volcanic Field, California

Notice, the region, which includes Long Valley, is known as a 'volcanic field'?

what is that? look at These Fault Lines. Red ones are named faults - notice the orange ones too?... The entire region appears shattered!

The Mono-Inyo Craters volcanic field developed along a 30-mile-long (50 km) fissure system that extends northward from Mammoth Mountain on the southwestern rim of the caldera to Mono Lake

Mafic eruptions began ... within the caldera and migrated to the north...

Rhyolitic volcanism began on the Mono Craters chain northwest of the caldera about 35,000 years ago. Mono Craters consists of a chain of at least 30 coalesced domes, flows, and craters. The youngest feature is only 600 years old.

These systems, part of the 'volcanic field' marched northward...

Could Markleeville be the next chain in the Long Valley link?!

heh... add another one:

It's not a matter of "feeling honored" or holding copyright deed or whatever, it's just neater to keep things to one thread if it's reasonably on-topic. (Which I think this is, but whatever man, I'm not the boss of you.)

I will say however, that there are hundreds of little quakes at/around Long Valley, and probably into the thousands if you include all quakes up to Tahoe, every month. If you list all of them in this thread it is going to be very, very long.

True. And rather than look at this as a diversion from the Long Valley thread per say, why not entertain this as a thread on something bigger than Long Valley... Not just about long valley?

Then you'll understand the reason for a thread separate from a notion of a Caldera known as Long Valley and understand HOW LONG Long Valley may actually be, as well as it's relation to YELLOWSTONE... LAKE TAHOE ....

and right now... MARKLEEVILLE ....


For instance I just now noticed this:

The earthquake flurries from 10/31 - 11/01 were rounded off at a depth of 23 kilometers. The earthquake flurries from 11/12 - 11/13 were rounded off at a depth of 19 kilometers. These recent flurries are at a depth of roughly 16 kilometers.

is something pushing through? Is it about to pop? with Long Valley rumbling right along with Markleeville... I believe it's a very good possibility.

Long Valley is actually pretty darned quiet right now, in comparison to how shaky it can get at times. The Western United States is geologically active. You could say the entire thing is connected if you wanted, and you wouldn't be wrong but you wouldn't be raising some amazing new theory, either. Really, if you want to get macrocosmic about it, the entire earth is a geologic system.

Lake Tahoe was created by faulting, and is in a very active fault zone. You will see a lot of earthquakes in the region. Posting them all is just going to give you carpal tunnel syndrome.

Posting them all is just going to give you carpal tunnel syndrome.

EEK! isn't that the persistant visual of a bad smelling fish at the end of the tunnel?!

Ah well, faulting - yes, that's the understood theory on the region - I wonder however... If a rhyolitic, basaltic disturbance or two could be found around the lake... or emerald bay... that would make the lake not only the by product of faulting - but also a by product of volcanism?

After all, Inyo, Mono, as well as Mammoth all have fissure activity...

A Good Example of a Volcanic Fissure

Could Long Valley be a rift zone in the making, as a by product of the Snake River Plain uplift?

hmmm....

ok, I know, new post on an old thread... but now there's a new flurry of what appears to be earthquake flurries (resembling a harmonic tremor?) comming from the Hawthorne, Nevada area... not exactly within the LV Caldera 'zone' but damn close enough to consider it a L.V. Caldera magma chamber extention possibility!

So what occurred at Markleeville, CA. (which is now quiet) is apparently now occurring at Hawthorne, NV.

all tho we do appreciate the work that went into this thread , only one thread is needed and that is the whats going on at long valley caldera thread .

I personally think the idea of "The Official This and That Thread" is out of hand on ATS, it creates an elitist mindset, and who the hell wants to read through 700+ pages? Who decides a thread is the 'official' thread anyway? I could get on here and post an "Official Obama Thread" and could live off the interest from the ATS points for the rest of my life, do we need that sort of farming going on? I understand the desire to collect information into one concise source, but that's what the entirety of ATS is isn't it? We should be encouraging new threads here, no offense but if I have to read 700 pages to find out 'what's going on at yellowstone' before I can post information about about the latest tremors there, I'm going to burn out pretty quickly.

lol, I couldn't have said it better myself! I mean the context of this thread is absolutely ignored by these people who instead want to try to supress individual contribution here on ATS - really It borders on a comment taken out of context and inappropriate for posting imho... Thanks for supporting my position twitchy!

DEPT. OF CONSERVATION’S CALIFORNIA GEOLOGICAL SURVEY ISSUES EARTHQUAKE SHAKING POTENTIAL MAP FOR RENO-TAHOE

April 26, 2005

INCLINE VILLAGE, Nev. – California and Nevada share more than just a border. They share faults. A map unveiled by the Department of Conservation’s California Geological Survey today shows earthquake shaking potential in the Reno-Tahoe area.

“The seismic hazard in the Tahoe area is related to faults on both sides of the California-Nevada border, which is why we’re involved,” said California State Geologist John Parrish, head of CGS. “Fault lines don’t care about state lines. We’re happy to work with our partners in this growing region of Nevada.”

The map covers Washoe, Storey, Carson City, Douglas, Lyon, Churchill and Mineral counties in Nevada, as well as parts of Nye and Esmeralda counties. Also included are all or parts of the following California counties: Lassen, Plumas, Sierra, Nevada, Placer, El Dorado, Amador, Alpine, Calaveras, Tuolumne, Mono, Mariposa, Madera, Fresno, Stanislaus, Merced and Inyo.

UNR Scientists Study Earthquake Faults at Tahoe Basin
By North Lake Tahoe Bonanza Jul 23, 2005

www.earthchangesmedia.com...

Schweickert and his colleagues have also found evidence of landslides and tsunamis in the Lake Tahoe Basin. Computer modeling shows that magnitude 7 earthquakes on submerged faults could generate tsunamis.

ok, I know, new post on an old thread... but now there's a new flurry of what appears to be earthquake flurries (resembling a harmonic tremor?) comming from the Hawthorne, Nevada area... not exactly within the LV Caldera 'zone' but damn close enough to consider it a L.V. Caldera magma chamber extention possibility!

So what occurred at Markleeville, CA. (which is now quiet) is apparently now occurring at Hawthorne, NV.
Your comments?...

Well it could be the US NAVY blasting out some tunnels for that Underwater Warfare Center submarine base at Hawthorne...

But I did post this in that other thread and it got missed in the ego war...

Quakes are here (box) near Mud Springs Volcano and Aurora Crater

Could it be the munitions bunkers being detonated Zorg?!



God knows there's miles of endless bunker rows out there, all loaded with munitions!

Lets see Hawthorne Ammo dump... check
NAVY Undersea Warfare Center submarine base Hawthorne... check
Multiple tremors in a tight area near Hawthorne on an unknown fault... check
Weird tremors on the charts... check

Hmmmm nah nothing to see here... move along now... its just normal activities
