Meanwhile, in Puebla . . .


See update at bottom of post, or click the Popocatepetl link at the top of this page.


This is a 2011 view of nearby Popocatepetl volcano from downtown Puebla.

Today, people in this Mexican city are watching Popocatepetl with concern (you can follow updates on its activity through the link in the top menu–it has been a bit more restless lately).

Reportedly (Spanish), Puebla State’s Civil Protection director has made a public statement. Per Google Translate of this linked news story:

Although in the last hours and days the Popocatépetl volcano has presented constant explosive activity, with incandescent fragments expelled by the crater, the Civil Protection director of the state of Puebla, Rubén Darío Herrera Cabrera, assures that it is a normal cyclic activity and that there is nothing to worry about.

The incandescent fragments, explained the head of Civil Protection, are pieces of the dome . . .

Even though spectacular fumaroles have been seen in recent days, the largest of which is 2,400 meters above the crater, there is nothing to worry about; “Another point that is constantly monitored is the seismicity and that is totally low, we have very few reports of seismicity, which gives us peace of mind,” said Herrera Cabrera, adding that the volcanic warning light continues in Yellow Phase 2.

This is an image from last night’s explosion as seen from one of CENAPRED’s webcams:

This is a night-time image, but the camera is a very good one and the Moon is quite bright. That’s chunks of incandescent material blown out of the crater, not flowing lava. Popo’s lava is very sticky and forms a dome in its crater that eventually pressurizes and blows up–apparently this is the demise of Dome #78. (CENAPRED)

Update, September 25, 2018: Popo got into a dramatic mood yesterday; updates are at the Popocatepetl link at the top of this page. Meanwhile, here is an eruption the volcanologists monitoring this volcano captured–it’s just one of several yesterday:

We have looked at some of these volcanoes before, but this video presents an in-depth look at the situation in the Pacific Northwest, as seen in the 1990s.

. . . and it will reward you with wonders.

Popocatépetl volcano in Mexico is currently in an active phase and I am live-blogging that. As part of the process, I save webcam images, from the three online volcano cams CENAPRED has set up around the volcano, and make time-lapse movies.

Anyone with a fairly recent computer (mine is four or five years old) and at least DSL speed on their Internet connection can do this easily. Continue reading
