Popocatepetl volcano news & eruption update
Popo sends his Christmas greetings with a moderate explosion that produced an ash column of about 2 km height and showering the volcano's top with incandescent fragments early in the morning of Christmas Day (Dec. 25, 2005).
Popocatepetl volcano had a moderate eruption Thursday morning, producing an ash plume about 5 km heigh.
No significant changes have been recorded at Popocatepetl volcano. Weak emission of ash and steam continue to occur at a rate of a few per day, lending a touch of romance to the snow-capped volcano.
No significant changes; activity remains low.
Activity at Popocatépetl volcano remains low. Some few relatively weak steam and gas emissions occur per day. The exclusion zone of 12 km around the volcano is being maintained by the authorities. Weak explosions that eject ash and incansescnet blocks above the crater rim could be expected at any time. (Source: CENAPRED)
Activity at Popocatépetl volcano is a low levels, although a low alert level and an exclusion zone around the volcano is being maintained for safety reasons, since an intensification of the eruption at any time cannot be excluded. During the past days, CENAPRED (the monitoring system of Popocatépetl volcano) registered a number of weak steam and gas emissions. In an aerial photograph taken on January 14th, subsidence is observed in the inner crater and no lava dome at the bottom of the crater could be observed.
Popocatepetl volcano, near Mexico City, continues to be active. After its last eruption that had ended in 1927, the volcano woke up from his slumber in 1994 and has since then been active, with changing intensity. At present, it seems to be rather quiet, with an average of 10-20 minor strombolian events per day, that produce nice ash and steam plumes that rise severl 100s of meters. No recent growth of a lava dome has been observed by CENAPRED, the ufficial monitoring organ hosted at the university of Mexico. Although much more violent activity in the near future is unlikely, a safety exclusion zone of 12km around the volcano is maintained.
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.
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
