Dokdo is the world's geological heritage
As mentioned above,
Dokdo is a volcanic island that was formed during the Pliocene in the 3rd phase of the Cenozoic Era, between about 4.6 million to about 2.5 million years ago. Thus, Dokdo is much older than Ulleungdo Island (about 2.5 million-10,000 years ago) and Jejudo Island (about 1.2 million-10,000 years ago).
Considering its age, Dokdo is like a big brother to Ulleungdo and Jejudo.
If 'The waters of East Sea dry up and the soils of Mt. Baekdu blow away,' as the Korean Anthem sings, Dokdo would no longer be a small rock island, but the tip of a massive mountain that is about 2,000 in height.
Geologically, Dokdo is a volcanic island that is formed by lava from underwater volcanic eruptions of the East Sea.
Originally, Dongdo and Seodo were not divided as they are today.
