I looked at the old seismograms from December 29th and they showed periods of a few hours of the same kind of readings that people here are speculating are harmonic tremors. I don’t know if they are or not, but I tend to think not since these seismograms are public info and I think we’d have heard about it in the media if harmonic tremors had been present for the past couple of days.

If this is a pending eruption, the good news is that it appears to be pretty localized which suggests that any eruption will be limited, which is very much the norm. There are something like 50 “regular” eruptions at Yellowstone for every super-eruption. So don’t jump off any bridges if you hear there has been an eruption.

Here’s the seismogram from Dec. 29th- looks like the same kind of thing we saw tonight.

So don’t jump off any bridges if you hear there has been an eruption.

If it pops off like the supervolcano, we'll won't need the news to tell us. We'll all hear it.

The modern MSM don't look for stories, they look for press releases; no press release, no story.
