Earlier this month, a small Indian mud volcano produced an unusually large eruption. This covered about half the size of a football field in a layer of mud 10 feet deep. But, why did this occur, and how does it relate to the area's geologic setting? Today's video answers these questions through the opinion and analysis of a geologist.
