Popocatépetl volcano (Mexico), activity summary 1-7 Aug 2012: gas and steak emissions, crater glow, occasional explosions
Wednesday Aug 08, 2012 12:05 PM | BY: T
During 1-7 August seismicity at Popocatépetl indicated continuing gas-and-steam emissions that may have contained ash during 4-6 August; cloud cover prevented observations during most of this period. Incandescence from the crater was periodically observed.
Gas-and-steam plumes were observed almost daily rising from the crater as high as 2.5 km above the rim. The plumes drifted SW and NW.
On 5 August ash plumes rose 1.5 km and drifted SW. On 6 August ash plumes again rose 1.5 km above the crater, and at 1758 an ash plume rose 4 km. Some explosions ejected incandescent tephra that landed on the flanks. Gas-and-steam plumes drifted SW the next day.

Popocatépetl's activity is relatively low. Only 14 weak emissons of mostly steam were recorded on 31 July during 24 hours, and there appears to be no significant seismic activity. Glow is still visible from the summit, but less than before. [more]

Exhalations of gas and ash have dropped to 1-2 per hour (versus 3-4 times per hour during heightened activity). Seismic activity is low. A small 1.8 volcanic earthquakes occurred at 11:36 local time on 30 July. ... [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.
