Steaming and glow from Popocatépetl this morning
Activity is on the increase again at the volcano, which currently is producing a strong steam plume illuminated by the glowing lava in the summit crater.

Steam plume rising from Popocatétpel today
A moderate-sized explosion occurred yesterday, producing an ash plume rising 1.2 km and throwing incandescent bombs to 500 m distance on the outer flanks of the volcano. Small explosions occur at an average rate of one per hour and a large steam plume is often rising to about 1 km above the crater. Incandescence continues to be visible at night at the crater.
Wed, 24 Apr 2013, 06:00
CENAPRED reported that during 24-27 April seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained ash. Incandescence from the crater was often observed at night. Gas-and-steam plumes rose 1 km and drifted NE and ESE.

View of Popocatepetl's glowing summit crater this morning
Activity continues with no significant changes: weak emissions of steam/gas/ash occur at rates of approx. once per hour, and glow at night shows that magma continues to arrive slowly in the summit crater.
Mon, 22 Apr 2013, 15:40
Activity has decreased to about one emission of gas/steam/minor amounts of ash per hour over the past few days. Glow remains visible at night from the crater.

The crater of Popocatépetl on 16 April (CENAPRED)
A stronger-then-usual explosion occurred last night (23:23 h local time) and produced a plume of ash rising about 2 km above the crater. Incandescent fragments were thrown to distances of 900 m.
Wed, 17 Apr 2013, 17:33
Activity has dropped a bit but remains essentially unchanged. CENPRED reported 1-2 emissions of steam and minor ash amounts per hour today, a steam and gas plume rising up to 1 km as well as continuing glow at the crater.

Ash emission from Popocatepétl this morning
The volcano remains in a state of elevated activity. Phases of medium to strong tremor occurred this morning at the volcano, although these were not associated by significant changes in the current observed activity: CENAPRED reported near-continuous degassing / steaming, and 35 emissions over the past 24 hours, the strongest of which ejected incandescent fragments out of the crater and produced small ash plumes rising up to 1.5 km height above the crater.

Ash emission from Popocatepétl
Another, but weaker episode of strong volcanic tremor and near-continuous emissions occurred yesterday at 15:50 (local time), creating a plume of steam, gas and ash rising 900 m and drifting NE. After a few hours, activity decreased again to individual small explosions at a rate of about 1 per hour, such as one captured on the webcam a few minutes ago.

Explosion from Popocatépetl yesterday night
Yesterday and during the night, the volcano experienced a phase of continuous emissions and explosions that ejected incandescent tephra onto the upper outer slopes of the volcano and created a plume of steam and some ash rising 500 m above the volcano. This was accompanied by strong tremor as well.

Current seismic signal from Popocatépetl
Wed, 10 Apr 2013, 15:32Activity has increased yesterday to about 3 emissions per hour and occasional small explosions creating plumes rising up to 500 m. Glow at the summit indicates continuing lava dome growth.
Wed, 10 Apr 2013, 06:00
CENAPRED reported that during 10-16 April seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained ash. Incandescence from the crater was observed at night and sometimes increased in conjunction with emissions. On 10 April gas-and-steam plumes rose 800 m above the crater and drifted ESE, and ash plumes rose 900 m and also drifted ESE.

Mon, 8 Apr 2013, 15:11The volcano has been comparably calm during the past days. CENAPRED reports an average of about 1 steam-gas-sometimes ash emissions per hour.
Sat, 6 Apr 2013, 14:58
No significant changes have occurred recently, but the volcano has been a bit calmer again yesterday and today, with an average of 1-2 weak emissions per hour.

Popocatépetl today
The rate of small to modest emissions dropped from 80 (yeesterday) to 36 today during the respective past 24 hours intervals. The largest explosion during the day occurred at 11:36 local time, and produced a plume with some ash content rising 2 km and drifting east.

Explosion yesterday night from Popocatépetl
An increase in activity occurred last night from 20:05 h local time. Small to moderate explosions with ash emissions started to become more frequent. Incandescent tephra was thrown to up to 400-700 m distances onto the northern and northeastern slope of the volcano (see picture).

Explosion from Popocatépetl at 22:00 on 26 March (local time)
the current phase of elevated activity continues. Emissions of steam and gas and small to moderate explosions have risen to an average of 3 per hour and sometimes merged into continuous activity yesterday and today. Some of the stronger explosions ejected lava bombs to distances of 1 km from the crater and produced plumes of steam and ash rising up to 1.5 km.

Wed, 27 Mar 2013, 06:00CENAPRED reported that during 26 March-1 April seismicity at Popocatépetl indicated continuing gas-and-steam emissions that contained ash. Although views of the volcano were often obscured by cloud cover, gas-and-ash plumes were observed daily. Incandescence from the crater was observed at night and sometimes increased in conjunction with emissions.

Explosion from Popocatépetl yesterday night
Activity has remained similar to previous weeks. The number of small explosions has risen a bit yesterday (1-2 per hour), and some of them were strong enough to eject glowing bombs to up to 500 m distance from the crater and creating ash plumes rising to about 23,000 ft (7 km) altitude or 1-1.5 km above the crater, drifting east.

Explosion from Popocatépetl yesterday night
Activity increased yesterday. CENAPRED reported 95 small to moderate gas-steam-sometimes ash emissions, a 5 times steep increase compared to the previous day. Some explosions ejected incandescent material to up to 500 m distance from the crater, and created ash plumes rising up to about 1 km drifting east.
