Popocatépetl volcano (Central Mexico) activity update: growing lava dome, occasional strong explosions ejecting ash to 8-10 km altitude

A moderately strong explosion occurred yesterday 7 Aug at 17:58 local time and produced a steam and ash column rising 4 km, and drifting W-SW, CENAPRED reported.
Since then, only a number of weaker explosions took place. Glow from the volcano at night remains strong, suggesting that the lava dome is growing.

Eruptive activity remains reduced at Popocatepetl, but the volcano continues to emit a significant amount of SO2, and volcanic tremor and lava glow are visible. In fact, Popo is known to be one of the top-performers of SO2 emission among all known volcanoes. [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.
