Occurrence of volcanic activity started some 30,000 years ago. Following roughly 5,000 years of dormancy, volcanic activity at Mount Koma-ga-take restarted in 1640,[2] triggering the Kan'ei Great Famine.[citation needed] Since then, there have been at least 50 recorded volcanic events at Mount Koma-ga-take.[3]
