The system also recorded 2 volcano-tectonic earthquakes, both of magnitude 1.1, at 13:52 h and 14:56 h in the afternoon 30 Sep. Additionally, there have been various pulses of very low-energy harmonic tremor reaching a total of 1 h 15 min duration, the most important between 08:25 and 09:05 h this morning.
For most of yesterday and today, cloud cover prevented visual observations, but during the night glow could be seen above the crater reaching about 200-300 m height and increased during the occurrence of major exhalations.
In the morning hours, the volcano showed a plume of water vapor and gas, about 500 m in height, heading south-southeast.

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.
