Popocatépetl - 02/04/2016 - destruction of the dome and aspect of the internal crater - Doc. CENAPRED

An overview of Popocatepetl this April 2 showed the destruction of the lava dome formed in January, and of an approximate volume of 2 million m³, by the recent activity.

The current internal crater measuring 325 meters in diameter to a depth of about 50 meters. Small landslides mark the wall of the internal crater, and clutter the bottom of the latter. Fumaroles are found in areas north, south and east.

In the last 24 hours, monitoring mentions 38 exhalations, 18 minutes harmonic tremor of low amplitude, and a night glow increasing in certain exhalations.
