Why does it smell like sulpher when you are near a volcanic mountain?

    Sulfur dioxide (SO2), is what you’re smelling. It’s one of the major gases that volcanos throw out. It can be a major source of pollution. You don’t want to breath much of it, because it can irritate your eyes and breathing. If there’s enough of it, it can kill you. The link below is a detailed but readable rundown of volcanic gases. Thanks once again, USGS!
