Good morning, Popocatépetl (with thunderstorm)!

Update, May 28, 2023, 10:07 a.m., Pacific: That is pretty much what Don Goyo has been steadily doing since around midday yesterday.

While it seems to be a lowered activity level to these untrained eyes, I note that CENAPRED has issued additional evening updates on its website recently, and this morning there was an official bulletin making the Twitter rounds (my main social media connection at the moment, other than this blog):

The tremor amplitude, they say, remains low, but CENAPRED this morning does mention over 1400 minutes of it in the last 24 hours.

Popo keeps chugging along.

Edit: Dr. Carlos Valdes explains why they look at tremor amplitude: per Twitter translation, “The amplitude decrease refers to the amplitude of the tremor signal, which represents the vibration caused by the exit of the material (ash and gas), more amplitude = more ash and gas. The amplitude value is added minute by minute (accumulated), for easy analysis.”

Some communities report ashfall, per CENAPRED. Here is the current VAAC ash advisory graphic:

Amazingly, Utah’s Salt Lake Tribune has found a local angle to use in reporting on how the volcano is monitored.
