During 21-25 September CENAPRED reported steam-and-gas emissions from Popocatépetl. An explosion on 26 September ejected incandescent fragments and produced an ash plume that rose 2.5 km above the crater. Following the explosion, a series of 11 gas-and-steam plumes containing small amounts of ash rose from the crater.

CENAPRED reported that on 29 August instances of emissions of gas, steam, and some ash from Popocatépetl increased. The next day an ash plume rose 1 km above the crater and drifted WNW, producing ashfall in San Pedro Nexapa (14 km NW) and Amecameca (19 km NW). CENAPRED noted that recent rain in the area may have contributed to the recent increase in activity.
