When most of us think of volcanoes, we think of mountains, rising and looming over flat plateaus. Cone-shaped and spewing burning ash and molten rock in flows of hot orange-red rock. Washington State's St. Helen's and Italy's Mount Vesuvius are famous volcanic explosions. And of course, the Hawaiian Islands-you can take a helicopter ride right over the smoking and steaming new coastline.
