Situated on the eastern seaboard of Jeju Island, Seongsan Ilchulbong, a UNESCO World Heritage Site, also called 'Sunrise Peak', is an archetypal tuft cone formed by hydrovolcanic eruptions upon a shallow seabed about 5,000 years ago.
Resembling a gigantic ancient castle, this 180-metre high tuft cone dominates the eastern seaboard of Jeju Island.
It not only preserves its bowl-like crater but also provides excellent sea-cliff exposures of diverse internal structures. These features provide a basis for interpreting the eruptive and depositional processes of hydromagnetic volcanoes in addition to the past activity of this tuft cone.
