So far highest magnitude looks to be 2.8 or so, but they are coming in fast. USGS has started posting the bigger ones:



Hopefully this dies back down and doesn't escalate.

I be a watchin, even at 3:30 AM.


Fortunately, these types of swarms happen from time to time at Long Valley, just like at Yellowstone. Just a heads up for those into this kind of thing.

Something is brewing there as its increasing in strength.

As scary as it might be to agree with you, that statement is not accurate. The 2.8 hit near the beginning of the sequence, and the quakes are actually decreasing in magnitude overall. I know. I am watching the live seismic data feed on my rig. Trust me. I shoot straight with this stuff and if quakes start increasing in magnitude from here, you can count on me to light up this thread with doom. Honestly, it is backing off already a bit. But that can change at any time. I'll be up for a while more, and I got this.


ETA: Update- Total die down of this swarm. No more quakes in over an hour. It's probably over. Check USGS site later to see if more quakes happen. As I said in OP, these kinds of swarms happen at LV, like Yellowstone. Quick bursts of activity, and then *poof* gone.

A 2.8 is equivalent to a squeaky earth fart in California--hell, even a 5.0 doesn't do much damage anymore.

While I appreciate the notice (I have family in Cali and on the NV side of Lake Tahoe), sub-3.0s literally happen all the time in California.

First post on ATS, I just wanted to say it's great to see some caring people that know what they're talking about.
Thanks for looking out.

I have noticed recently, Swarms in Nevada by DEAD Volcanos near by this swarm last month. Swarms off the coast of Cal/Or. and in southern Or at the tri-state area OR/CA/NV. Read thast USGS has been monitoring and replacing Monitors in these areas due to fast moving underground Magma Flows Deep. From the sierra nevada up to the northern range of the Cascades Rockies, Specifically Mt. Shasta, Mt. Hood and by Mt. St. Helens again.

I have noticed Just a theory that these seem to Coincide with Solar Storms and CME's.

We had the Tsunami warning horn blow here yesterday lasted for maybe 3-4 minutes Del Norte county scared the Shiitakes out of me! Nothing listed for tests that I can find, there were none planed.

I'm sorry, I don't use FB either, but I do know that they and other municipalities will have some blup regarding things like that.

LOL!!! Jeez I thought I was the only person that didn't go on to fb. At least that's what others tell me. LOL!!!

Hi, just wondering if you could link a source regarding your statement that I bolded.
Thanks,

I can not remeber but it was the USGS scientist(s) that stated that, and that they were replacing / upgrading sensors in NV around Hawthorn due to the earthquake swarm in amoungst dead Volcanoes. it was Definitely USGS. And the Lava flow was there also Hawthorn NV there are 4 dead Volcanoes there.

Hmm, well getting some minor quakes coming back now, in different parts of the caldera at once. Check USGS, and set to 1 day all magnitudes to see them. I be a watchin.

Uh oh, I just checked the depths of those quakes at the supposed base of Mammoth Mountain (a known resurgent lava dome) and look:



Now that can't be good. And the other ones read the same. That means the quakes happened above sea level, and are beyond shallow. Better watch this. And Yellowstone's fidgeting too right now with some quakes just incoming at the lake.

Oh hell. It's going to be a long night. ^sigh^

I can't tell if this new activity is on the southern caldera boundary, or just outside it. There was a mag 1.6 at 00:47 UTC, then 15 hours of quiet, until this Mag 3.8 popped. It has been followed by 9 aftershocks.

Or you can follow the action at the Calvo Long Valley monitoring page.

Hmm, the epicenters are outside the caldera's southern boundary, meaning that the quakes are most likely tectonic in origin (not from magma intrusion).

This is odd, or at least not the typical mainshock-aftershock decay pattern. Just now there has been a Mag 3.5 It's more like a swarm, with random magnitudes over a small area for an extended period.

Hi folks, I don’t use FB either and sort of avoid people who do.

This is just a throw in. You are welcome to throw it out.

I overheard just snippets of a frightening conversation three years ago, while in Reno and waiting for a rental office to open, and we had gone for an unexpected lunch before hand at an Indian buffet. I am pasting a portion of the letter that I sent to a friend on April 26, 2014.

Heads up, the devil talk was metaphorical. My friend and I had come from religious backgrounds so it was part of our personal slang. It had to do with adapting, ad nauseam, to being in a place we didn’t want to be in. If I could add anything to the description, and I should add this, it is that having been to many conferences, it was apparent that these two men didn’t know each other but were familiar with each other’s work, and were trying to be courteous and professional; but I caught a glimpse of the fear in their eyes, when I found an excuse to turn around for a moment in their direction. The restaurant was noisy and I was straining to ease drop and even compelled several times to simply ask as if I could join them, but it was apparent that they were already nervous and being cautious even in how they spoke to each other.





We had found a really cheap apartment in Reno and we were about to sign the lease when we overheard some geologists talking at lunch at a near by table about the odd phenomena of the huge clusters of earthquakes in Reno and the Sierra Nevada. In fact, there have been 43 of them this morning alone, and it is only 12:45 right now. I will see if there were more even as I type. The fact is, it felt like we were selling our souls to the devil, or rather the devil was stealing our souls just because we weren't putting up a fight. Finding ourselves at that restaurant at that moment was providential as far as I'm concerned because that was the last straw for me. Listening to these two geologists talking about their fear of what was about to happen, which he said was unprecedented in history, and in his opinion with the entire Sierra Nevada about to "shear off" and asking the advice of who to approach in the government and how to keep his professional credibility and asking how many people lived along the Sierra Nevada and then just hearing him sigh -- that was enough for me to say that enough was enough and I would not sign that apartment lease.


Even though we moved far away from there, literally all dressed up with no place to go, I still keep up with the quakes. Since then I’ve learned about that horrible practice of fracking and I suspect that some of it is that, but being somewhat familiar with the area, some of the places would be too difficult to get to with equipment, although others seem like this could be the case, as they are in extremely remote areas that have roads near by. But having driven through Hawthorn many times, the idea of earthquakes being centered around there is rather frightening. For that matter, if you want to feel some alarm, just get close enough on your zoom-in on Google to see where the simple two train tracks at both ends of town actually go within the complex. But that’s a different matter. All those bunkers though, or whatever they were, were always a creepy sight.

Anyway, keep a pair of shoes near by! Beyond that, I don’t know of anywhere that is safe anymore. I used to read every earthquake email I get, since I signed up for these notifications, but lately I spend more time erasing them, unread, than it used to take to read them!

I'd have to agree with your assessment that they are likely tectonic, being outside the caldera boundaries. I can also offer the following:

If you'll check the GPS stations at LV, it appears just in the last couple of months in the vertical data for 2016, most of the stations are showing the inflation reversing, and moving downward now. And if that's the case, we could be in for more quakes there, much like at Yellowstone when the caldera deflates. There seems to be more seismicity at these monsters in deflationary periods for some reason, and scientists aren't exactly sure why.

That said, however, over the last many months I have noticed periods when all the stations at LV start ghosting with tiny, tiny little signatures, all at once. It may be just telemetry error. But it may not. I have to comment that it reminds me of pre-eruption precursors I've seen in the data at Okmok in Alaska in 2008. And it's one of the reasons I have been paying very close attention to LV recently- just in case it isn't telemetry error. You just never know with these beasts how the data is going to look days and months and even years before one of them finally blows.
