Stages of Activity Volcanoes have different stages of activity. An active volcano is one that is erupting or showing signs of erupting soon. A dormant volcano has not erupted for a while, but is expected to erupt in the future. An extinct volcano will probably never erupt again. Monitoring Volcanoes Geologists use a variety of technical instruments to study volcanoes and predict eruptions. Earthquakes, increases in ground temperature and escaped gases provide warning signals of potential eruption. clouds of ash & gases lava flows fires Destruction Caused by Volcanoes Volcanoes can cause widespread damage. Huge clouds of ash may bury towns, and volcanic gases can be deadly. A lava flow covers everything in its path and can start fires and landslides.
