dormant volcanoes
Quiet fire mountains
Dormant volcanoes are volcanoes that haven't erupted in recorded history but retain the potential to erupt again—distinguished from extinct volcanoes, which are considered permanently inactive, and active volcanoes, which show recent or ongoing activity.
The classification involves geological judgment; some "dormant" volcanoes have awakened unexpectedly: Mount St. Helens was considered dormant before its 1980 eruption.
