Photo: Mexico's Popocatepetl volcano erupts mongabay.com December 3, 2007
The first eruption occurred at 6:20 a.m. local time (1220 GMT) and a total of six eruptions took place in 24 hours. According to local media, ash rained down in Mexico City, located some 70 km northwest of the volano.
The name Popocatépetl comes from the Nahuatl words popoca 'it smokes' and tepetl 'mountain', meaning "Smoking Mountain", according to Wikipedia.

Volcanic eruptions in Iceland shrunk Nile River (11/21/2006) A series of volcanic eruptions in Iceland in the 18th century dramatically impacted the mighty Nile River according to a new study published in Geophysical Research Letters. The research, partly funded by NASA, shows that volcanic eruptions in high latitudes can greatly alter global climate and distant river flows. The scientists found that Iceland's Laki volcanic event, a series of roughly ten eruptions from June 1783 through February 1784, altered atmospheric circulations across much of the Northern Hemisphere, reducing rainfall over much of the Nile River watershed and producing record low river levels. The researchers said that the Laki event had a significant impact on climate because it released large amounts of aerosol-forming sulfur dioxide into the atmosphere. The aerosols, which cool climate by reflecting incoming sunlight into space, may have reduced the average temperature over Northern Hemisphere land masses by as much as 3 degrees Celsius in the summer of 1783, according to computer models used in the study. Volcanic eruption cut warming in 20th century (2/9/2006) Ocean temperatures might have been warmer and sea levels would have risen higher in the 20th century had Krakatoa not erupted in 1883, said a team of scientists. According to the researchers, the release of ashes and aerosols into the upper atmosphere had a significant long-term impact on global climate. Poisonous volcanic gas probably caused worst mass extinction says new study (12/2/2005) The mass extinction event at the end of the Permian -- where more than two-thirds of reptile and amphibian families perished and 95% of oceans life forms became extinct -- was probably caused by poisonous volcanic gas, according to research published in the journal Geology. The researchers believe that volcanic gases from the eruption depleted earth's protective ozone layer and acidified the land and sea. News index | RSS | Add to MyYahoo!
