Mount Drum: Geological Insights

Mount Drum, a stratovolcano in Alaska, is considered extinct but shows unusual activity. Dead vegetation and songbirds are linked to high carbon dioxide emissions from vents. Mud volcanoes, not lava, erupt due to these emissions. Evidence suggests a magma chamber beneath, indicating potential volcanic activity. Earthquake clusters support this theory. Mount Drum may be dormant, with a low chance of eruption, or a new volcano may form. The video concludes with acknowledgments.
