Indonesian authorities raise the alert for Mount Bur Ni Telong volcano due to increased activity, including numerous earthquakes. The development is reported from Indonesia’s westernmost province of Aceh, where the volcano is located.
Mount Bur Ni Telong Volcano & Stratovolcano (Composite Volcano) :
| Dimension | Key Details |
|---|---|
| Current trigger | Indonesian authorities raise the alert for Mount Bur Ni Telong due to increased activity, including numerous earthquakes. |
| Volcano type | Active stratovolcano. |
| Location | Indonesia’s westernmost province of Aceh. |
| Elevation | ~ 2,624 meters above sea level. |
| Geomorphology | Conical volcano. |
| Geological setting | Constructed at the southern base of the massive Bur ni Geureudong volcanic complex, described as one of the largest in northern Sumatra. |
| Composition and hazard | Formed by multiple layers of lava and eruptive materials; prone to explosive eruptions and described as highly hazardous. |
| Shape and features | Provides for a tall, steep, cone-shaped volcano; has higher peaks than flat shield volcanoes; at the peak usually has a small crater. |
| Typical occurrence | Subduction zones; Ring of Fire that frames much of the Pacific Ocean. |
| Global share | Comprises the largest percentage (about 60%) of the Earth’s individual volcanoes. |
| Eruption character and lavas | Most are characterized by eruptions of andesite and dacite; these lavas are cooler and more viscous than basalt, allowing gas pressures to build up to high levels and resulting in explosive eruptions. |
| Materials and alternative name | Usually about half lava and half pyroclastic material; layering gives them the other common name of composite volcanoes. |
| Crater condition | Crater may be filled with water or ice, or may contain a volcanic dome during a period of relative inactivity. |
