Good morning, Popocatépetl! This live link shows a calm volcano at the time of writing, but as they note — for how long?

Update, June 1, 2023, 8:30 a.m., Pacific: Yesterday, after noting at 7 p.m., local time, that —
At the moment, the high-frequency tremor signal has decreased. Eventually, episodes of low amplitude and short duration occur. This tremor signal is associated with the emission of slight amounts of ash and the occasional expulsion of incandescent fragments.
— the science committee reported through the CENAPRED website that they are keeping Popocatépetl at YELLOW, PHASE 3.
This, after the governor of Puebla State said, when interviewed (autotranslated), that he felt they could return to YELLOW, PHASE 2. He did add that the committee had the final say.
His point of view is understandable. We see fire mountains as mountains, and this one appears calm at the moment.
The boffins, however, are aware of the fire and, given the short time elapsed since Popo had what I called “high-end strombolian activity,” they must also look at it as though this was a pressure cooker on a hot burner.
- Has the “burner” temperature really gone down enough to lower the alert?
- Is the lid safely vented, or is this seeming quiet actually a sign of a blocked vent, which would make the “pressure cooker” pressurize?
- Given that open conduit, I wonder if they could tell — far enough ahead of time to warn everyone — if another eruption activity boost, as intense as recently or even more so, was on the way. The volcano does have a history of plinian activity, though this layperson’s money would be on an extensive lava flow a la the Nealtican flow only smaller (since the recent uptick was much smaller than the Lorenzo pumice eruption), if what we saw was just a newly arrived magma packet, degassing.
It’s tricky, and almost thirty million lives are ultimately at stake.
They ended VAAC advisories overnight, but Washington VAAC did note, as always, that new emissions were possible at any time, given recent activity.
Well, let’s wait and see how the day goes.
