Popocatepetl volcano (Mexico): alert level raised
Mittwoch Apr 18, 2012 19:39 | VON: TOMPFEIFFER
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.
Local 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.
A larger eruption is likely to affect air traffic around Mexico City as well.

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. ... [mehr]

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.
