Mt. Etna Releases Smoke Rings

Mt. Etna-the active stratovolcano, on the east coast of Sicily, has released smoke rings into the sky as of August 16, 2011. References I have are from the MSN News and they were recorded by male on video. It was released the day of the smoke rings and it does indeed impact our Earth by the gasses and chemicals it releases. I get my information from the video , a website , and wikipedia . All references were used as either proof/evidence, background information, or for chemical information.
Mt Etna is one of the most active volcanoes in the world. It is in an almost constant state of activity all the time! The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower sides of the mountain and the Plain of Catania all the way to the south. Deemed by the United Nations, it is also one of the 16 Decade Volcanoes that should always be studied for further information; such as when an eruption may occur, how dangerous it might be, and -if need be- when to evacuate. This Volcano has eruptions often and recently. However it has an unusual characteristic of Smoke Rings. It is extremely rare and was first captured in the 1970s, then again in 2000 and 2011. As well as most recently, August 16, 2011.
Honestly, this had caught my attention. It did so for a couple reasons. The first reason, the one that caught me the most, was because it seemed highly interesting. What I mean is, the video thumbnail was still framed on an odd smoke ring in the sky. That then made me wonder what it was, so I checked out it’s title and short but to the point description to learn that it was from Sicily’s Mt Etna Volcano. I was then interested but began to wonder what chemicals are released from the gasses that Volcano had to release for the smoke and ring, as well as how could it impact our planet? So, I did some further research to learn it’s impact. I believe this video was quite a hook to peak my interest.
Beneath the Volcanoes surface the gasses are turned into molten rock but as it becomes active the gasses begin to rise and turn into smoke. This impacts our Earth and causes air pollution. When a volcano releases smoke it lets loose chemicals into the air we breath. It allows Sulfur dioxide (SO2), Hydrogen sulfide (H2S), Carbon dioxide (CO2), Hydrogen Chloride (HCl), Hydrogen Fluoride (HF). On August 16, 2011 all these chemicals were released into the sky above Sicily when Mt Etna released its Smoke Rings. I believe this impacts our Earth with its pollution, as well as how it impacts us to be careful and study this active volcano to be sure all can stay well for the people of Sicily.
