Apparently there was a 1.6 yesterday at 01:43:35 PST depth 0.6 mi below the SW flank of Mt Adams (which I can see from where I sit, clouds cleared today).

Yep! The vert low level seismicity is continuing, but has backed off from where it was about a month ago.

Even if you know where the previous caldera is, a volcanoes the size of the one 700kya is going to pretty much erupt where it pleases. The second thing is these hotspots are on the move so…… My question for Yellowstone is how far out does the ground sensing equipment go, particularly the thermal sensing equipment.

[@michaelpoland529]

Thermal monitoring is done in two ways. First, we have thermisters in many individual features (hot springs, geysers, etc.). That provides information on local activity that might indicate changes in how a feature (like Steamboat Geyser) is behaving. Second, we use satellite data to look at entire regions. In this sense, the thermal monitoring extends as far as you want it to go. It is using thermal (and also some optical) satellite data that we were able to discover the new thermal area near Tern Lake in 2018, and also identify previously existing (but unrecognized until recently) subtle thermal areas that had escaped notice from ground-based surveys. You can see some examples of these datasets in the annual reports -- search for "2023 Yellowstone Volcano Observatory annual report," for example.
