Activity has been very low compared to previous days. During the last 24 h, 4 low-intensity exhalations occurred and were accompanied by weak continuous emission of water vapor and gas. During the night, incandescence was observed on the crater. Additionally, yesterday at 17:32 h local time, a volcanic quake of magnitude 1.2 occurred. [more]

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.
