This Week in Volcano News; Yellowstone Earthquake, Unrest at Andes Volcano

In the last week, there was significant seismic activity at a large volcano. One of these volcanoes has an ongoing intrusion of magma at 3 miles or 5 kilometers depth in Chile and could produce an eruption in the next several months. Also, in Yellowstone National Park, a magnitude 4.2 quake occurred which led some people to speculate that it was volcanic in origin. And, in Australia, the nation's most active volcano produced a new eruption, sending a lava flow 2.5 kilometers downslope. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.
