Weak steam explosions occur at frequencies of about 1 per hour. The largest reach 1 km height and contain small amounts of ash, such as at 22:03 on 29 Aug, 00:57 and 02:38 local time on 30 Aug. Glow from the crater is visible at night suggesting that the lava dome is continuing to grow slowly. CENAPRED also registered 3 small volcano-tectonic quakes at 19:51, 19:58 local time on 29 Aug and 10:37 on 30 Aug. [more]

A slight increase in activity can be noted since yesterday. There is about 1 weak steam explosion per hour, with an increase in frequency last evening. Some of the explosions produce small amounts of ash and plumes up to 1.5 km high, such as one at 03:56 early yesterday. Glowing material can be seen ejected during such events at night. ... [more]

Not much has changed at the volcano. A slight increase in the frequency of small explosions to about 1 or 2 per hour can be noted. Some of the explosions produce not only steam, but some ash, and the more powerful ones eject glowing material falling back into the crater. ... [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.
