🌋 Jeju Volcanic Island and Lava Tubes: Geomunoreum Lava Tube System
🌋 Jeju Volcanic Island and Lava Tubes: Geomunoreum Lava Tube System
UNESCO-designated underground lava cave network on Jeju Island
- UNESCO World Heritage Site inscribed in 2007
- Located on Jeju Island, South Korea
- Formed by basaltic pahoehoe lava flows during the Holocene epoch
- Contains rare lava stalactites, stalagmites, and well-preserved flow lines
Geomunoreum is a lava tube system located on Jeju Island that formed through successive volcanic eruptions and pahoehoe lava flows spanning thousands of years. The tubes preserve rare geological features including lava stalactites, stalagmites, and flow lines that document the cooling and crystallization of basaltic lava. The site was inscribed as a UNESCO World Heritage Site in 2007 due to its scientific significance and exceptional representation of volcanic processes.
