I'll tell Yogi and BooBoo  

You got people issuing warnings again ......

Where are we supposed to go?  Last time I looked at anything about it, I'm pretty sure they said Texas could get several inches of ash, which would wreck farming and ranching and pretty much everything. Even IF the eruption itself didn't get us, the aftermath would.
Are the new warnings less scary?

Yep, the cadence continues; “Emergency Emergency Emergency”.

As Covid fades the next Emergency is …….

Yellowstone isn't simple.

The swollen caldera's swell is also being affected by continental drift over the hot spot so you got to balance the drift "net rock thickness" and the swell numbers to decide if there is a significant magma bubble rapidly swelling up under Yellowstone or not.

If something shifts rapidly, there are modern alerts in place which include monitored laser reflectors which measure swell relative to mountains that are outside the caldera.

Plain GPS from orbit can accurately see movements measured in 10s of yards.  Lasers from satellites bouncing off reflectors can see down to the single yards precision levels.   Dedicated "sideways" lasers from fixed positions (mountain tops outside the caldera zone) can see to the vertical foot (measuring relative to "fixed" locations that are also subject to the same continental drift effects, etc.)

They also are using the sonic version of an ultrasound, kinda like they do on pregnant women but in this case for rocks and magma chambers.  They have mappings of the relatively long tapering off in the direction of drift travel Yellowstone magma chamber.  The "density of the magma" can be judged for how liquid it is this week vs last week and this too is being tracked over time .......

Yes, the main Yellowstone magma chamber is slowly growing and the shrunken floor of the Yellowstone Caldera is slowly getting taller and taller.

The rate of mini-quakes are slowly going up.  Steamboat and Old Faithful say that things underground are happening somewhat quicker over time.

One issue is that the best of these new metrics is that they are technically brand new and do not have whole decades of tracking data to support any sort of summary judgements.   A century of geyser data says there are cyclical things involved here with a known up-down pattern.

I would guess that we in our generation are pretty safe, but our great great great grandkids may actually see some molten hot stuff eventually happening ........

The guys in Italy have much more pressing issues with their not so dormant normal volcanoes relative to Yellowstone's much more massive but much slower moving problems.




General population numbers in Colorado are decreasing ..... folks are choosing not to live close to the Yellowstone action zone.
