An active volcano is a volcano that has erupted in the recent past. The mantle contains a weaker zone known as the asthenosphere. Magma is the material present in the asthenosphere. Material that flows to or reaches the ground comprises lava flows, volcanic bombs, pyroclastic debris, dust, ash, and gases.
