CENAPRED reported that each day during 16-23 November there were 9-29 steam-and-gas emissions from Popocatépetl that drifted NW, NE, and E. At 1714 on 19 November an explosion generated an ash plume that rose 2 km above the crater rim and drifted NE. A minor explosion at 0230 on 21 November generated an ash plume that rose 600 m and drifted NW, and at 0136 the next morning another small explosion produced an ash plume that rose 800 m and drifted NE. ...

Background:

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.
