The activity of the volcano continues at low levels over the past month.
The volcano is currently a bit calmer than usual, with only venting of water vapor and gases emissions from the summit crater. The degassing activity produced 102 emissions with small amounts of ash which drifted SW.
The seismic instrument recorded 9 min / day of volcanic tremor and continues at deeply under the average-than-usual levels (approx. 1000 min / day).
In addition, a volcano-tectonic earthquake with magnitude M 1.5 was detected.

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.
