Whats going on at yellowstone?

Well, it wouldn't need to be the old, huge shaker trucks from 20-30 years ago. I suspect that they could get by with much smaller devices now because the geophones could be more sensitive and the amplifiers and data processing could be more able to filter out noise, etc. Thus, a smaller amount of shaking might be practical.

And yes, they could run them 24-7 if they wanted to do so. If they were really concerned about this, they'd just man them as needed. Or they could be automatically operated remotely, etc............

They could even be some kind of interference to which the seismograph detectors happen to be sensitive.

I have ZERO evidence that this is from some kind of shaker device or devices being used to map things. It's just a thought.

Yeah, avalanche danger would preclude using them in this environment, I would think. People are skiing all over the place, it would probably be a bad idea.

Now back to my regularly scheduled totally baseless speculation:

I wonder if we'll see less uniform signals from Lakeway again now that we're seeing big spikes.

Having worked for the Govt. in a previous life that would honestly NOT surprise me unfortunately.

Quoted from the report:



So officially there's nothing unusual at the moment beneath the lake? What are those strange geyser-like readings of increasing frequency over time on LKWY then? Or is this report outdated even though it's from today?

What about this:

Could the folks up at Yellowstone be using "shaker trucks" to try to map the various underground features in the area, perhaps to see if things are changing shape?

The signals we're seeing on the various seismographs might well be the signals from such shaker trucks being used.

They're big trucks, and people would probably see them moving around in the area. But it'd be easy enough to get a few of them up there and put them to use like this.

Back in the last oil boom around here, I knew a couple of people who worked on crews doing this kind of mapping. This was more acceptable in certain areas than setting off dynamite. It's also faster to set up and move. In an area like Yellowstone, they'd want to be as environmentally sensitive as possible, so to me, shaker trucks make some sense for mapping things underground.

They'd array their trucks in some kind of a pattern or line. Then they'd set them up with hydraulic pads pushing down onto the earth and raising the truck up slightly.

Then they'd synchronize all of the trucks together to a master sync signal via radio link, and start them all up at once. Inside each truck was a huge mass that was coupled to the pad pressed against the ground by very large and powerful actuators.

The masses would all be moved in unison to create the wavefront that was desired, and the data from this would be recorded by an array of "geophones" that they'd deploy.

At the time, the bottleneck was the computing power required to process and analyze the data from the geophones to create an image of what lies below ground. That was always a big part of the proprietary IP that these companies used.

These days, I'd expect that end of things to be much more sophisticated and the processing to be much faster.

Anyhow, the idea of shaker trucks just comes to mind when I see those patterns that we're calling "secret geysers" on this thread.

It'd explain the very uniform and controlled appearance of the amplitude of the signals we're seeing.

Thoughts?

Would we see the consistent inverse correlation between duration and interval we are seeing if it was shaker trucks?
