CENAPRED reported that during 28 August-3 September seismicity at Popocatépetl indicated continuing emissions; cloud cover sometimes prevented observations of the crater. Incandescence from the crater was observed on most nights. On 28 August gas, steam, and ash plumes rose 200-800 m and drifted SW.

Activity has not changed much and been relatively calm with 1-2 usually small emissions on average per hour. Glow remains visible at the summit.

Current seismic recording from Popocatépetl
At 19:02 h (local time) yesterday, an phase of strong ash emissions occurred accompanied by strong volcanic tremor. Due to cloud cover, the eruption was not observed directly, but fine ash fell in areas west of the volcano, including the towns of Ozumba and Tepetlixpa in the State of Mexico.

Wed, 14 Aug 2013, 06:00CENAPRED reported that during 14-20 August seismicity at Popocatépetl indicated continuing emissions; cloud cover sometimes prevented observations of the crater. Incandescence from the crater was observed and occasionally intensified with some emissions. On 14 August a period of tremor was accompanied by an ash emission that drifted W.

Ash plume from an explosion from Popocatépetl yesterday morning
Activity has remained more or less at similar levels during the past days. During 11-12 August, CEAPRED reported 88 mostly weak emissions and a stronger explosion yesterday morning that produced an ash plume rising about 2.5 km above the crater.

Ash eruption from Popocatépetl yesterday (CENAPRRED webcam)
Activity has been stable with little changes. The rate of emissions decreased yesterday to about 1-2 per hour, but some small to moderate explosions still occur from time to time, producing ash plumes up to about 1.5 km height.

A trend of slowly increasing activity has been apparent over the past days. For the 24 hour interval of 3-4 Aug, CENAPRED recorded 93 emissions, i.e. about 4 per hour, and seismic activity has been stronger recently as well.
Sat, 3 Aug 2013, 09:42Activity has been more or less stable at relatively low levels. During 1-2 Aug, the rate of emissions climbed to about 3 per hour, and some tremor episodes were recorded as well as at least one (non observed) explosion event.
Wed, 31 Jul 2013, 06:00
CENAPRED reported that during 31 July-6 August seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained ash; cloud cover often prevented visual confirmation. Incandescence from the crater was occasionally observed. On 31 July a clear decrease in the size of the water vapor and gas plumes was observed; plumes were pushed by winds down the NW flank and rose only 100 m above the crater rim.

Small explosion from Popocatepétl yesterday
The rate of small emissions of steam-gas and sometimes ash has risen to more than 3 per hour again, and CENAPRED recorded 150 minutes of low and high frequency tremor.
Thu, 25 Jul 2013, 14:18Emissions have been up to 2 per hour on average, but remained very small. A volcano-tectonic magnitude 2.3 quake occurred at 00:47 (local time) yesterday.

CENAPRED reported that on 23 July the Coordinación Nacional de Protección Civil (CNPC) of the Secretaría de Gobernación (SEGOB), CENAPRED, and a Scientific Advisory Committee lowered the Alert Level at Popocatépetl to Yellow, Phase Two. Access to the crater within a 12-km radius was prohibited.

Wed, 24 Jul 2013, 03:58Following the relatively calm phase over the past week, CENAPRED lowered the alert level back to Yellow phase 2 (from 3).
Wed, 24 Jul 2013, 02:22
Activity has been low during the past days. Emissions of steam, gas and only sometimes small amounts of ash occurred at rates fluctuating between 0-3 per hour and plumes reached a maximum of about 1 km above the crater.
Mon, 22 Jul 2013, 02:33The volcano has quieted down and produces only smaller emissions of mainly steam and gas at rates of 1-2 per hour.

Activity has been comparably low with an average of 1-2 emissions of steam and gas, sometimes some ash, per hour during the past days. The strong explosion from 12 July has effectively destroyed the new lava dome, an aerial inspection via helicopter on 15 July showed.

Wed, 17 Jul 2013, 06:00CENAPRED reported that during 17-23 July seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained ash; cloud cover often prevented visual confirmation. Incandescence from the crater was occasionally observed. On 17 July an explosion was detected at 1516.

View of Popocatépetl this morning
Activity has remained stable, with an average of about 2 emissions per hour of mostly low intensity. No larger explosions have occurred since the past update. Bright glow from the crater and a significant SO2 plume indicate that magma continues to rise within the volcano. Although activity is back to levels comparable to most of the previous months, the alert level remains at Yellow phase 3 (but might be soon lowered again to phase 2).

Activity, both external and internal, has significantly calmed down during the pasts day. The volcano is now back to emit a steam/gas plume with more vigorous emissions and weak explosions of mainly steam and gas with minor amounts of ash at rates of 1-2 times an hour.

Glowing bombs from Popocatepétl's explosion early on 12 July
A large explosion took place at 03:10 local time on 12 July (08:10 UTC). Incandescent bombs were ejected to considerable distances and rolled down to distances of 4 km (!) from the crater and ignited small bush fires on the slopes, in particular on the eastern slope of the volcano.

CENAPRED reported that scientists aboard an overflight of Popocatépetl on 10 July confirmed the presence of a new lava dome that was 250 m wide and 20 m thick. During 10-16 July seismicity indicated continuing gas-and-steam emissions that sometimes contained ash; cloud cover often prevented visual confirmation. Incandescence from the crater was observed at night during 9-11 July.

Steam and ash plume rising from Popocatepétl today
The volcano has been a bit calmer today, but still emits an impressive steam plume with some ash most of the time as well as occasional smaller explosions. VAAC reported the plume height at 22,000 ft (7 km) altitude drifting SW.
