The Secret of the Giant Cauldron: The Breath of Antiquity Encountered at Myeonbongsan Caldera (Cheongsong National Geopark)

Have you ever heard the word ‘caldera’? It might sound unfamiliar, but it refers to a magnificent landform that encapsulates the grand history of our Earth. Particularly in Cheongsong, Gyeongbuk, there exists a Myeonbongsan Caldera (Cheongsong National Geopark) that has been hidden for a long time. What secrets might be hidden here?

A caldera, meaning ‘large cauldron’ in Spanish, is a cauldron-shaped basin landform created when the ground collapses after magma has drained away following a volcanic eruption. As if drawn on a colossal natural canvas, Myeonbongsan Caldera fully reveals the traces left by intense volcanic activity during the Mesozoic era.

Embracing the Earth’s Time: Formation Process of Myeonbongsan Caldera

Among landforms that embrace the Earth’s grand history, calderas are particularly mysterious. Myeonbongsan Caldera (Cheongsong National Geopark) was a massive basin, formed as a result of Mesozoic volcanic activity, measuring 10km in diameter. Although its boundaries have disappeared due to long-term erosion, leaving only its ‘roots,’ standing here, one can still feel the ancient energy.

Caldera, A Giant Cauldron Forged by Nature

Shall we look a bit more closely at the principle of calderas? When magma rises to the surface during a volcanic eruption, the space where magma was collected underground becomes empty. As this space can no longer support the overlying land, a massive block of land collapses downwards, forming a unique cauldron-shaped landform, namely a caldera.

• Past of Myeonbongsan During the Mesozoic era, a powerful volcanic eruption occurred in the Myeonbongsan area, leading to the creation of a massive caldera measuring 10km in diameter. Traces of its collapse, up to 820m deep, still remain throughout Myeonbongsan.
• Similar Calderas Although only the roots of Myeonbongsan remain, the majestic appearance of a typical caldera can be directly observed in Baekdusan Cheonji or in Japan’s Aso Geopark, which has a sisterhood relationship with Cheongsong Geopark.
• Geological Value Myeonbongsan Caldera, one of the core areas of Cheongsong National Geopark, is an important geological heritage that allows us to imagine the Earth’s past, and showcases the constantly changing power of nature.
