Ulleungdo · A volcano beneath the island

Rocks of different ages and later landform changes · modern map location

Interpretive landscape and schematic explaining modern Nari Basin and Ulleungdo’s submerged edifice; not photographs, surveyed sections, magma-storage images or precise reconstructions of past terrain.

Ulleungdo is the exposed upper part of a larger volcanic edifice extending below the sea. Rocks and layers record different episodes of activity; Nari Basin and Albong provide clues to later collapse and eruptions.
