Recently, Indonesian authorities heightened the alert level for Mount Bur Ni Telong due to a noticeable increase in seismic activity, including numerous earthquakes. This heightened alert underscores the potential hazards posed by this active volcano.
Located in Indonesia's westernmost province of Aceh, Mount Bur Ni Telong is an active stratovolcano standing approximately 2,624 meters above sea level. This conical volcano is situated at the southern base of the massive Bur ni Geureudong volcanic complex, one of the largest in northern Sumatra.
The stratovolcano's structure consists of multiple layers of lava and eruptive materials, which contribute to its susceptibility to explosive eruptions. As such, it is considered highly hazardous for climbers and nearby residents.
A stratovolcano is characterized by its tall, steep, and cone-shaped profile. Unlike flat shield volcanoes, stratovolcanoes have higher peaks and are typically found above subduction zones. Many of these volcanoes are part of extensive volcanically active regions, such as the Ring of Fire, which encircles much of the Pacific Ocean.
Stratovolcanoes constitute the largest percentage (~60%) of the Earth's individual volcanoes. They are primarily noted for their eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt. This viscosity allows gas pressures to accumulate, often resulting in explosive eruptions.
Typically, stratovolcanoes are made up of roughly equal parts lava and pyroclastic material. This layering contributes to their alternative designation as composite volcanoes. At their peaks, stratovolcanoes generally feature a small crater, which may be filled with water or ice, or contain a volcanic dome during periods of inactivity.
Q1. What recent activity has been reported for Mount Bur Ni Telong?
Answer: Indonesian authorities have raised the alert level for Mount Bur Ni Telong due to increased seismic activity, including numerous earthquakes, indicating potential volcanic threats.
