“An explosion on 17 June produced an ash plume that rose more than 4 km, and ejected incandescent tephra [rock fragments] up to 2 km from the crater. Some of the high-temperature fallout caused small fires in grasslands on the flanks.” This is the description of Popocatépetl’s most recent activity from the Smithosonian’s Global Volcanism Program. The video above is from a June 25 flyover of the temperamental volcano located 43 miles southeast of Mexico City and whose name in Nahuatl means Smoking Mountain.
Here you can see a time-lapse video of the June 17 explosion. Is El Popo telling us a bigger eruption is coming?
