Activity has decreased to about 2 weak emissions of steam and gas, sometimes some ash per hour.

Eruption from Popocatepétl this morning
A few hours ago, another moderately strong explosions occurred at 14:48 h local time, which threw incandescent fragments at distances of 100 m from the crater and generated an ash column reaching nearly 2 km in height, which was dispersed towards the northwest. The alert level remains unchanged at Yellow Phase 2.

CENAPRED reported that at 1448 on 18 June an explosion from Popocatépetl generated an ash plume that rose 2 km above the crater and drifted NW, and ejected incandescent tephra 100 m from the crater. During 19-25 June seismicity indicated gas-and-steam emissions that sometimes contained small amounts of ash; cloud cover often prevented visual confirmation although plumes were observed most days. Incandescence from the crater was occasionally observed and sometimes increased with accompanying emissions.

A powerful explosion occurred yesterday at 13:23 local time, producing an eruption column rising about 4 km. This is so far one (if not the) largest single eruption in the present cycle of activity.

Eruption from Popocatepétl yesterday morning
Activity has been elevated. During 15-16 June, CENAPRED recorded 3-4 emissions per hous, including a few stronger explosions. One yesterday morning threw incandescent fragments on the north side at a distance no greater than 500 m.

Eruption plume from Popocatepétl yesterday
Activity has picked up during the past 2 days, as the preceding earthquake swarm had suggested. CENAPRED reports emissions at a rate of 2 per hour. The more vigorous explosions have produced ash plumes of up to 3 km height. The largest was an explosion yesterday just before 17:30 (local time).

SO2 plume from Popocatépetl (NOAA)
The rate of emissions has dropped to less than 1 per hour, but more (small) earthquakes have occurred and a large SO2 plume is visible yesterday on satellite images, suggesting that new magma could be currently intruding at depth.

A cluster of several (7) volcanic earthquakes up to magnitudes 2.4 has occurred this morning, perhaps heralding some more vigorous activity in he near future.
Wed, 12 Jun 2013, 06:00
CENAPRED reported that during 12-18 June seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained small amounts of ash; cloud cover often prevented visual confirmation. During 12-13 June a total of about 45 minutes of low-amplitude harmonic and high frequency tremors were detected. An explosion at 1716 on 14 June produced an ash plume that rose 1.5 km above the crater.

Sat, 8 Jun 2013, 15:43Given the currently low activity (1-3 weak steam and gas emissions per hour), CENAPRED has lowered the alert level back to "Yellow Phase 2".

Activity has not changed much and remained comparably low, with about 3 weak to moderate emissions of steam and gas per hour. Occasionally, some of them contained small amounts of ash.

Wed, 5 Jun 2013, 06:00CENAPRED reported that during 5-11 June seismicity at Popocatépetl indicated continuing gas-and-steam emissions that sometimes contained small amounts of ash; cloud cover often prevented visual confirmation. Incandescence from the crater was observed some nights; during 8-9 June incandescence increased with accompanying emissions. On most days steam-and-gas plumes were observed drifting SW and SSW.

Ash emission from Popocatépel yesterday
Activity has been reduced during the past days. Occasional explosions produced steam and ash plumes rising about 1 km above the crater and the frequency of small emissions has been about 3 per hour.

Fri, 31 May 2013, 13:31Activity has continued to decrease and there have been no new significant explosions. The number of steam-gas emissions (which sometimes contain also small amounts of ash) has dropped from an average of 5 per hour to only 2 per hour last night.

Current seismic recording from Popocatépetl
An earthquake swarm and tremor pulses occurred today, which could suggest new magma on the rise, but this has (not yet) resulted in particular surface activity which remained rather calm. Degassing (SO2 emissions) remains strong.

CENAPRED reported that during 29 May-4 June seismicity at Popocatépetl indicated continuing gas-and-steam emissions that contained variable amounts of ash; cloud cover often prevented visual confirmation. Incandescence from the crater was often observed at night. On most days steam-and-gas plumes were observed drifting SW and SSW.

Explosion from Popocatépetl this morning
An explosion early today at 05:03 h (local time) ejected incandescent fragments to 1.5 km distance from the crater on the northeastern slope and generated a column of ash that reached more than 2 km height above the crater and was dispersed to the SW.

The volcano's activity has been reduced compared to a week ago, but still produces occasional explosions with plumes of up to 2 km in height, and many smaller emissions, accompanied by low-level harmonic tremor and a continuous steam plume rising about 1 km.

SO2 plume from Popocatépetl (NOAA)
Activity has not changed much, but perhaps decreased a bit today. During the last 24 h, CENAPRED recorded 3 explosions of moderate intensity, yesterday at 15:40 h, this early morning at 06:46 h and at 10:00 h (local time). All of them were accompanied by a column of gas and ash of 1.5, 1 and 2 km height, respectively.

Powerful explosion yesterday at 02:54 local time (CENAPRED webcam)
Activity, both internal and external, remains elevated. A constant steam plume can be seen rising on webcams and a steam-gas-ash plume rises up to about 1.5 km above the volcano. The seismic signal shows frequent earthquakes and emission events.

Activity has been showing an increase today. Yesterday, CENPRED reported near-continuous emissions of steam and gas and sometimes ash. Some larger explosions occurred at 12:13 h and at 12:34 h local time yesterday. Both produced an eruption column about 1.3 km high and drifting west. Bright glow and strong steaming are currently visible from the webcam images.

CENAPRED reported that during 22-28 May seismicity at Popocatépetl indicated continuing gas-and-steam emissions that contained variable amounts of ash; cloud cover occasionally prevented observations, especially during 26-27 May. Incandescence from the crater was often observed at night.

Glow from Popocatépetl's summit (CENAPRED webcam)
Activity has been a bit calmer over the past 2 days, but the number of emissions and small explosions (about 3 per hour) remains elevated. Explosions ejected incandescent fragments to heights of 500 m above the crater. Strong glow is visible at the volcano's summit at night. Intermittent phases of volcanic tremor and volcanic earthquakes of magnitude up to 2.1 have been registered. The volcanic alert level remains at YELLOW Phase 3.

Activity remains elevated, but the number and size of explosions have decreased during the past 2 days. CENAPRED made an overflight and found that the series of recent explosions since 14 May, in particular the two that occurred on the night of the 16th to 17th, have excavated a crater of approx. 200 m diameter and 40 m depth in the lava dome. The rest of the dome's surface is covered by fragments from the explosions.

Eruption from Popo this morning (CENAPRED webcam)
Activity remains intense. Last night at 22:14 and this morning at 00:29 h local time, two strong explosions occurred and ejected incandescent fragments on all the volcano´s flanks to distances of up to 1,500 m from the crater. The explosions triggered an eruption plume rising at least 3 km above the volcano, drifting northeast.
