What Lies in the Interior of a Volcano; Video Footage w/ Geologist Analysis

Ever wondered what the interior of an active volcano looks like? Well, with spectacular drone footage, we can now answer that question, by descending deep into the crater more than half a thousand feet below ground. Spectacular colorations from sulfur and arsenic, additional chambers, and other fascinating sights. Today's video will analyze this footage through the analysis of a geologist at Indonesia's Egon volcano.
