Popocatepetl Crater Overflight This Morning

This is also in the Popocatepetl updates (see link at top of page), but it’s awesome enough to share in a separate post, too.

The volcanologists say the dome is 250 meters (roughly 820 feet) by 30 meters (98 feet) and has a volume of 1.5 million cubic meters/530 million cubic feet. Extrusion rate is 31 cubic meters/1,100 cubic feet per second. (Again, this type of volcano has “sticky” gray lava, not “runny” red lava like Kilauea.)

Per CENAPRED’s post this morning (via Google Translate and my own translation, with added link)

In the last 25 years of activity of the Popocatépetl volcano, 80 domes have formed; the recording of their growth and subsequent destruction has been possible thanks to the overflights made with the support of the Ministry of the Navy and the Federal Police.

In addition to the overflights, it should be noted that the monitoring of the Popocatépetl volcano includes seismic, geochemical, geodetic monitoring, remote sensor image analysis, etc.

The National Center for Disaster Prevention issues a bulletin [here it is in English] every 24 hours on the activity of the Popocatépetl volcano 365 days a year. Any change in the activity of the volcano is communicated in a timely manner by the official accounts of Civil Protection @PcSegob.

Of note, here is a time-lapse video of four webcams showing Popo this moring; of course the scale is too big to see the helicopter.
