Weak steam and sometimes ash explosions continue about every 2-3 hours. Otherwise, a strong steam plume is being emitted and satellite imagery show that there is still a lot of SO2 production from the volcano. At night, glow from the crater is visible, suggesting that the lava dome continues to grow slowly. [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.
