About this video

Military Warfare:Volcano Hunter

More than 50 volcanoes erupt somewhere on earth every year. That's nearly once per week on average. More than half a billion people live on their slopes or near them. The Four Horsemen of the volcanic apocalypse are hot ash, rock fragments, lava and gas. The flow down a volcano’s mountainside can reach 200 or more kilometers per hour. When it does, a group of scientists using the most modern technology will be the first to sound the alarm.
