How dangerous are Antarctica's volcanoes? While many people do not think about potentially hazardous volcanoes on the icy continent, they do exist and have the potential to effect people outside of Antarctica. Today's video will discuss all of the continent's known or suspected active volcanoes and assign them a hazard rating through the opinion & analysis of a geologist. Thumbnail Photo Credit: A.
