Harmonic tremors in CA?

I have been watching the live stream of a CA simograph on and off all day. Since morning there have been a lot of little tremors with some 3-4 mag. thrown in. I am no expert, and the explanation this morning was traffic causing a lot of the small ones.

Last night, it was fairly quiet, with larger 3-4 mag. thrown in every hour or so.

For the past couple of hours, it has been even more active with small stuff, that looks bigger than just traffic noise.

They do look a lot like harmonic tremors. I am no expert though. Thoughts from anyone with more experience?

A harmonic tremor is a sustained release of seismic and infrasonic energy typically associated with the underground movement of magma, the venting of volcanic gases from magma, or both. It is a long-duration release of seismic energy, with distinct spectral lines, that often precedes or accompanies a volcanic eruption.

Yellowstone ?

Ridgecrest

I have been watching the USGS and it is very interesting to me. I have zero geological expertise but given the frequency of these it does seem to be a ‘harmonic tremor’, to me atleast.

I wonder if there are any implications (or intertwined changes) for the Yellowstone volcano. It almost seems like there is a lot of magma activity happening far below southern CA— and given a super volcano is within its vicinity it just makes me wonder

Literally took my thoughts out of my head as I was typing the reply. Great minds think alike

Right. That is why I was asking. They just resemble harmonic tremors to me. Nothing like it did last night.

Could, just possibly, the earthquakes have triggered a rupture down deep, and magma is flowing though the fault? Just a theory.

HAARP was RE-classified in 2014, so we can't blame it for its ongoing global atrocities as new arrays are installed worldwide.

Well hopefully it doesn't come out at Yellowstone. One of my sister lives a bit too close to it. She does worry about it too.

Not sure if it's related but I read an article earlier today on Drudge about the higher than normal activity of the geysers.

The Steamboat Geyser in Yellowstone National Park is approaching a record number of eruptions

Not the link but the title of the article.

Why Yellowstone? Wouldn't Long Valley Caldera be closer? Yeah, actually, it would and Mammoth Lakes, both of which are volcanic sites themselves. But Coso Volcanic field is even closer than both of those.

184 miles by road, probably less than 150 as the crow flies to Long Valley from Ridgecrest. Yellowstone is almost 1,000 miles away. Long Valley makes more sense.

Don't borrow trouble. The odds of this being a massive magma movement are small. More likely this is simply seismic buildup, but that doesn't mean it won't create tension at various points across the country, including at Yellowstone and other points around.

I wouldn't worry too much about Yellowstone going boom out of this.

There's original info on that in the eq threads here today . Saying about their seeing recently blasted vegetation and excess heat at the geysers.

Sorry not from the US . Guessing too . Long Valley then , along the boundary line forming the edge of the tectonic plate . Does magma flow have much to do with subduction perhaps

What about coso volcanic field

a reply to: DoctorBluechip

Possibly. Not an expert.

Maybe it is a new "hot spot" forming? Only 150 miles from a known caldera, possible I suppose.

Wow!!! Less than 50 miles from Ridgecrest. Interesting. Never heard of it before. Going now to look into it.

Subduction zone volcanism occurs where two plates are converging on one another. One plate containing oceanic lithosphere descends beneath the adjacent plate, thus consuming the oceanic lithosphere into the earth's mantle. ... These trenches are the deepest topographic features on the earth's surface.

I think "toysforadults" may be right!

Most of the small tremors today have been located near Little Lake Ca. Little Lake is only 13 miles from Coso Volcanic Field.

Coso is a large producer of Geothermal energy, enough to power 270,000 homes. It also has hot springs, steam vents, and mud pots. So for sure it is a hot spot with magma near the surface.

Last eruption was dated to 40,000 years ago, with about 40 eruptions in the last 250,000 years.

At this point, I would say that it is no coincidence that we are seeing what looks like harmonic tremors, only 13 miles from a known geothermal hot spot. Maybe Coso is waking from its 40,000 year nap?

You understand that HAARP only has an effect in the ionosphere, ... or you should.

It looks like magma flow moving north if you see the USGS map and most of the eqs are happening in that area now at 2.5-3
