Popocatepetl is one of Mexico's most active volcanoes. After almost 50 years of dormancy, "Popo" came back to life in 1994 and has since then been producing powerful explosions at irregular intervals. In the past centuries befor European invasions, large eruptions produced giant mud flows that have buried Atzteque settlements, even entire pyramids.
Popocatépetl volcano (Mexico): video of strong explosion yesterday 13:23 local time

Current seismic recording from Popocatépetl showing the explosion yesterday
A powerful explosion occurred yesterday at 13:23 local time, producing an eruption column rising about 4 km. This is so far one (if not the) largest single eruption in the present cycle of activity. A video from webcamsdemexico on youtube shows the impressive eruption:
Today, the seismic recording suggests a small decrease in activity.
Activity has been elevated. During 15-16 June, CENAPRED recorded 3-4 emissions per hous, including a few stronger explosions. One yesterday morning threw incandescent fragments on the north side at a distance no greater than 500 m.
Activity has picked up during the past 2 days, as the preceding earthquake swarm had suggested. CENAPRED reports emissions at a rate of 2 per hour. The more vigorous explosions have produced ash plumes of up to 3 km height. The largest was an explosion yesterday just before 17:30 (local time). ...
The rate of emissions has dropped to less than 1 per hour, but more (small) earthquakes have occurred and a large SO2 plume is visible yesterday on satellite images, suggesting that new magma could be currently intruding at depth. ...
Given the currently low activity (1-3 weak steam and gas emissions per hour), CENAPRED has lowered the alert level back to "Yellow Phase 2".
Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
