Active - inactive

All volcanoes which had eruptions after ice age (within the last 10000 years) and / or have active hydrothermal areas within their vicinity and / or have earthquakes and / or other caracteristic movements of terrain (resurgent domes, intrusions etc.) are called "active" by geologists. Not only in case of eruptions!Hornstrandir1 (talk) 16:24, 17 November 2018 (UTC)
