Starting yesterday, a new microquake swarm started in the southwestern part of the caldera- inside the caldera:
What's curious about this one is it seems to be spread out in a wider area than usual. Most of the time they tend to stay in one area.
Recently in the last year, I have been noticing activity spread out across the whole area, and sometimes multiple areas activating at once in small
spurts of seismicity. I asked one of my contacts if scientists might be interested in this- or if this could be interpreted as a change in seismic
activity characteristics. Because I feel it is important to note any change in character at a place like Yellowstone. After all, no one knows what the
exact symptoms would be in the event of an eruption with a magma chamber from a supervolcano. It's just so darn big, I question if it would behave
like other volcanoes when it finally blows its top. We just don't know. Therefore, it would seem important to pay attention to even minor
I found it interesting they did not comment on that one.
Now particularly curious, is that these recent events have been occurring close to station MCID, which has been exhibiting some interesting signatures
lately. I have been told that it is interpreted as wind noise. Although, I am still unclear about that, because of the exact frequency content that is
registering for those signatures. It is extremely low, and imo, a lot lower than just about any other wind noise I have experience observing on
spectrograms. So to me the jury is still out on that, even though I have not much choice but to accept their assessment.
So when these events started occurring near there, I just have to wonder. Anyways, just posted cause I won't be around as much the next few days, and
I need for the observant to pay attention please to what's going on out there. Stations to watch are YPP, YLT, YFT, YMS- as concerning this location
of this swarm. BUT, the more serious watchers here, please pay attention to all stations. I am curious if more seismicity shows up in other areas.
Also, note that the highest magnitude here is a 3.0 with several other 2+'s:
