Each day during 28 June-4 July CENAPRED reported 67-240 steam and gas emissions from Popocatépetl, some of which contained minor amounts of ash. Explosions were detected on 28 June (4), on 30 June (1), on 2 July (5), and on 3 July (1), though cloudy conditions prevented visual confirmation of possible ash, gas, and steam plumes. Minor ashfall on 2 July was noted in Ozumba, Amecameca, Tlalmanalco, Chalco, Ayapango, Tenango del Aire, and San Pedro Nexapa.
An explosion at 1145 on 4 July generated an ash plume that rose 2.5 km above the crater rim and drifted W. The Alert Level remained at Yellow, Phase Two.

Popocatépetl volcano Volcanic Ash Advisory: VA EM OBSD

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.
