 Ash eruption at Popocatépetl volcano on 2 May 2012 (CENAPRED webcam images)
Popocatépetl volcano continues to produce ash and steam eruptions several times a day, that generate plumes rising up to 1-2 km above the crater. A more powerful emission is in progress at the time of writing (see image). [ read all]

The weekly Smithsonian/USGS volcanic activity report summarizes the recent increase of Popocatépetl volcano as follows: ...moreDuring 11-15 April steam-and-gas emissions from Popocatépetl occasionally contained ash; emissions contained a substantial amount of ash on 12 April. Seismicity increased on 13 April and at 2220 an explosion ejected incandescent blocks that landed on the NE flank as far as 500 m away from the crater rim. A larger explosion at 2236 ejected incandescent blocks that landed even further away on all flanks; an ash plume rose 2 km above the crater and drifted ENE. Ashfall was reported in San Pedro Benito Juarez (10-12 km SE), where the explosion was also heard. [ less] [ read all]

CENAPRED has raised the alert status of Popocatépetl to the third highest level (5 out of 7) and considers the possibility of a major eruption. The volcano continues to have elevated levels of seismicity, and produces frequent steam and ash emissions raising about 1 km above the crater. ...moreLocal authorities are preparing for potential evacuations. The last time evacuations were ordered on a large scale was in 2000 when over 50,000 people had to leave their homes. The major hazards of a larger eruption would be ash falls, pyroclastic flows, lahars produced by mixing of water and tephra. [ less] [ read all]

Popocatepetl volcano near Mexico City had one of its largest eruptions this year yesterday 16 April. An explosion produced an ash plume rising 2 km and caused ash fall, up to 7 cm thick, in over 30 communities near the volcano. Strong incandescence can be seen at night from the summit, suggesting that fresh magma is arriving there building up a new lava dome. ...moreAn 12 km exclusion zone was declared around the volcano.

Popocatepétl volcano in Mexico has been showing signs of increased activity recently, The National Center for Disaster Prevention (CENAPRED) reported yesterday. ...moreDuring 24-25 March, the volcano had 33 small steam and gas emissions, accompanied by small earthquakes and volcanic tremor. On Saturday night, incandescence was observed at the crater. CENAPRED recommends a safety radius of 12 kilometers around the volcano as eruptions with higher intensity could occur any time.

 Webcam image of Popo showing the glow at the summit crater (CENAPRED)
Popocatépetl volcano's activity is increasing. On 25 Jan at 10:10 local time, an ash explosion produced a plume of 3 km height drifting NE. During the past days, strong degassing and steaming has been observed as well as periods of low-frequency tremor. At night (see webcam image), a constant glow can be seen from the summit crater, suggesting that the lava dome might have started a new phase of growth. ...moreAuthorities recommend a safety distance from the volcano of 12 km radius, and the alert level remains at "yellow".
