The word volcano originates from Vulcan, the Roman god of fire. Revered and sometimes feared, volcanoes blast lava, steam, and ash, serving as emphatic reminders of just how dynamic Earth is. Members of the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) contributed the photographs and scientific information in this spectacular Volcanoes square wall calendar.
