extinct volcano
Permanently inactive mountain
An extinct volcano is one that has not erupted in recorded history and is not expected to erupt again.
The magma source has cooled or shifted, leaving the volcanic structure dormant permanently rather than temporarily: Mount Kenya is an extinct volcano.
Compare with dormant volcanoes, which are inactive but could potentially reawaken.
