Aerosol Eruptions

Volcanoes produce ash and prodigious amounts of sulfur dioxide, a colorless gas with a pungent odor. Sulfur dioxide interacts with air to produce sulfate aerosols. Volcanoes can launch sulfates high into the stratosphere, where they can persist for years. Global temperature fell by half a degree when just one volcano—Mount Pinatubo—erupted in 1991 and produced large amounts of light-reflecting sulfates, which act like a mirror over Earth, reflecting radiation away from the surface.

    Hi,if you want to know more abouth predictions of heartquake,and vulcanos,please see in my galery a link to the web of study of scient of Spain aboth this fenomenous,you can found a link in a photograf of moon in my galery,please,give time at the script or anuncements,or spot,of this web,dont warry for the clam to sites not recomend,there are only a games and other cuestion,but the site was property of Lycos,now is property of,and this vulcano of the Canary Island was predited,another site to teme of this study,
    I post the e-mail with prediction of the vulcano for Canary Island in Isla de La Palma,or nearest,for 2012..with other predictions..thank you for see that..this vulcano of this photograf is coming with the cicles with other vulcanos to come back with the Canary Island..
  • Pedro Ramon Rodriguez Quintana 4y

    oh,sorry,this fotograf not,i think in the Islandia vulcano of nearest to day,anyway,all vulcanos are potsible to relationship one of anothers of the teory,influencias indirectas de la luna,for impacts of cosmic dust acumulate in Lagrange points over the Heart,between Moon and Earth when is down for solar wind..thank yo..
