Geological Marvel
The Tengchong Volcanic Geothermal Area (TVGA) is one of China's youngest and most active volcanic fields, formed by the collision of the Indian and Eurasian tectonic plates. Key features:
- 97 dormant volcanoes, including the "Big Dipper Cluster" (7 conical peaks resembling Ursa Major).
- 80+ hot springs, with temperatures up to 102°C at the Great Boiling Pot (a 6m-wide boiling pool).
- Rare phenomena: Columnar jointing (hexagonal basalt formations) and hydrothermal explosions.
Scientific Significance
- Magma chambers at 25km depth fuel ongoing geothermal activity.
- Unique ecosystems: Acid-tolerant algae thrive in hot springs like Frog Mouth Spring.
- Research hub: Studies here inform global volcanic risk models.
Top Attractions
