The latest Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been published by the Global Volcanism Program, covering the week 14-20 March 2012. The report is compiled by Sally Kuhn Sennert. Among the highlights of this week:

  • A plume, probably water vapour, seen from Iliamna, where seismicity remained elevated
  • Seismicity decreased at Nevado del Ruiz but significant gas emissions continued
  • Etna continued lively with lava flows and fountaining, and strong ash emission
  • Daily explosions at Shiveluch produced plumes which reached 3-5 km altitude

Popocatépetl throws out a 3-kilometre plume 3 June 2011

Posted by admin in activity reports, Mexico, Popocatépetl.

Popocatépetl ash emission, 3 June 2011 (EFE)

It’s not uncommon for Popocatépetl, the volcano which overlooks the Mexican capital, Mexico City, to produce fumarolic activity and small ash emissions: Popocatépetl is an active, restless volcano. For an ash plume from Popocatépetl to reach an altitude of 3 kilometres, however, is unusual, and the event has attracted considerable interest both within Mexico and elsewhere. A small but significant eruption this morning threw out a considerable ash emission that reached 3 km into the sky and produced ashfall in some nearby districts. The fact that this volcano, with a long history of sometimes dangerous and destructive activity, is close neighbour to one of the world’s great cities means that its behaviour is very carefully watched. Mexico’s CENAPRED have said that today’s activity is still within normal parameters for Popocatépetl, but have warned people to stay at least 7 km away from the summit.

More on this here tomorrow [EDIT: the eruption at Puyehue has pushed our Popocatépetl coverage back a day — hope to write more on 5 June]. And there’s much more information about today’s events at Eruptions: Moderate ash plume at Mexico’s Popocatépetl.

The Daily Volcano Quote: lofty Popocatépetl 24 September 2010

Posted by admin in daily volcano quote, Mexico, Popocatépetl.

Orizaba we were yet to see; but nothing could, we thought, exceed in interest the distant view of Popocatepetl from the top of our hotel in the City of Mexico, as the setting sun gilded its snowy dome, as it went down painted its snow fields with roseate hues. It is the grandest mountain summit of the valley of Anahuac. It repeats, but with emphasis, the purity of form and massiveness of Mt. Shasta, in Northern California. Its twin sister, the volcano of Iztacihuatl, or the “snowy woman,” forms a part of the same isolated range – the Cordillera of Ahualco – and was doubtless thrown up at the same time; but it has no central dome cleaving the sky, the mountain mass extending as a range running nearly north and south, with three broken irregular snow-covered summits, of which the central is the highest, reaching an altitude of 4786 meters or 15,705 feet above the sea. The height of Popocatepetl has been variously estimated. Humboldt placed it at 5400 meters, or 17,716 feet; Guyot gives its altitude as 17,784 feet; Humboldt’s measurement combined with those of two later observers, is 17,853 feet, while the French savans of the Maximilian expedition put it as high as 18,362 feet.

A. S. Packard, ‘Ascent of the Volcano of Popocatepetl’, The American Naturalist, vol. 20, no. 2 (February 1886), p. 109. For the record, the summit of Popocatépetl is 5426 metres or 17,802 feet above sea level.
