In addition to the Chile volcanic activity, much closer to home is the volcanic activity present in Mexico. Popocatépetl, whose name is the Aztec word for smoking mountain, located 70 km SE of Mexico City and is North America's second-highest volcano.

Mexico's National Center for Prevention of Disasters (Centro Nacional de Prevención de Desastres, or CENAPRED) reported that during 31 May-1 June steam-and-gas emissions from Popocatépetl occasionally contained small amounts of ash. On 3 June an ash plume rose 3 km above the crater following seismic tremor. The lower-altitude portion of the plume drifted W towards the state of Morelos, and the higher-altitude portion of the plume drifted ENE over Puebla 40 km E. Within a few hours ash-fall was reported in the Morelos state, the municipalities of Tetela del Volcán (20 km SW), Zacualpan (31 km SW), Jonacatepec (43 km SW), and Axochiapan (60 km SSW). At 9:12PM a high-frequency, low-amplitude tremor was detected that was followed by an ash plume at 09:16PM that rose 1 km above the crater and drifted W. By 09:30 activity had returned to normal levels. On 4 June an ash plume rose 1 km above the crater and drifted SSW at lower altitudes and NE at higher altitudes.
