An active volcano is one that has erupted in recorded history, and was observed erupting. A dormant volcano has not been seen to erupt, but it shows evidence of recent activity. When a volcano shows no signs of life and exhibits evidence of long-term weathering and erosion, it is tentatively identified as an extinct volcano. This title is tenuous, as it is not speaking to an absolute dormancy, rather an observed dormancy, leaving room for the volcano to come to life again with little warning. A great number of active continental volcanoes lie in or near spreading and subduction zones. Many of the world’s most famous mountains are volcanic peaks standing astride or near plate margins: mount fiji, Mount Versuvius, Mount St Helen's and Mount Rainier.
