About Mount Bur Ni Telong:
- It is an active stratovolcano.
- It is located in Indonesia’s westernmost province of Aceh.
- It is one of the best climbing spots in Aceh.
- The conical Bur ni Telong volcano was constructed at the southern base of the massive Bur ni Geureudong volcanic complex, one of the largest in northern Sumatra.
- It is formed by multiple layers of lava and eruptive materials, making it prone to explosive eruptions and highly hazardous.
What is a Stratovolcano?
- It is a tall, steep, and cone-shaped type of volcano.
- Unlike flat shield volcanoes, they have higher peaks.
- They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
- Strato Volcanoes comprise the largest percentage (~60%) of the Earth’s individual volcanoes, and most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
- These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions.
- They are usually about half-half lava and pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.
- At the peak, stratovolcanoes usually have a small crater. The crater may be filled with water or ice, or it may contain a volcanic dome during a period of relative inactivity.
